2376981-2 : js-yaml library vulnerability CVE-2026-53550

Component: REST Framework and TMOS Platform

Symptoms:
The js-yaml library (version 4.1.1) included in BIG-IQ management UI was vulnerable to an algorithmic complexity denial-of-service attack (CVE-2026-53550, CVSS 5.3 Medium). A crafted YAML document using repeated aliases in a merge-key sequence (<<) could trigger quadratic CPU exhaustion, blocking the Node.js event loop for seconds with a relatively small payload (tens of KB).

Conditions:
BIG-IQ systems running versions that include the js-yaml library (version 4.1.1) in the bigiq-mgmt-guiserver component.

Impact:
A remote unauthenticated attacker could cause denial of service by supplying a crafted YAML document that exhausts CPU resources during merge-key processing on the BIG-IQ management UI server.

Workaround:
None required. The vulnerability has been addressed.

Fix:
The js-yaml library in the BIG-IQ management UI has been upgraded to version 4.2.0, which resolves the CVE-2026-53550 algorithmic CPU exhaustion vulnerability in merge-key processing.

Fixed Versions:
8.4.2.2


2376689-1 : CVE-2026-48779 ws: ws: Denial of Service via memory exhaustion from small WebSocket fragments

2304693-12 : Improvements in HTTP/2 on TMM

Links to More Info: K000162231


2286445 : CVE-2025-69873: Regular Expression Denial of Service (ReDoS) Vulnerability in ajv

Component: REST Framework and TMOS Platform

Symptoms:
ajv (Another JSON Schema Validator) before 8.18.0 is vulnerable to Regular Expression Denial of Service (ReDoS) when the $data option is enabled. The pattern keyword accepts runtime data via JSON Pointer syntax ($data reference), which is passed directly to the JavaScript RegExp() constructor without validation. An attacker can inject a malicious regex pattern (e.g., "^(a|a)*$") combined with crafted input to cause catastrophic backtracking. A 31-character payload causes approximately 44 seconds of CPU blocking, with each additional character doubling execution time. This enables complete denial of service with a single HTTP request against any API using ajv with $data: true for dynamic schema validation.

Conditions:
This issue arises when the $data feature is enabled in ajv and unvalidated input is passed to runtime schemas containing the pattern keyword.

Impact:

2256705 : Re-importing BIG-IP LTM device into BIG-IQ fails with "not authenticated" error when log-config filter/publisher objects are out of sync

Links to More Info: BT2256705

Component: BIG-IQ Local Traffic & Management

Symptoms:
When attempting to re-import a BIG-IP LTM device into BIG-IQ, the operation fails during the COPY_CONFIG step with the following error:

Failed to copy configuration to working-config; reason: Failed copying from source to target: java.lang.RuntimeException: not authenticated

The failure occurs during bulk update operations involving log-config filter and publisher objects.

Conditions:
-- Log-config publisher objects exist on both BIG-IPs

-- Log-config filter object exists only on one BIG-IP

-- After modifying the log-config filter on the BIG-IP with the filter, and re-importing into BIG-IQ, a sync gap is created

-- Re-import triggers a bulk update, targeting the device missing the filter

Impact:
Users are unable to re-import BIG-IP LTM devices into BIG-IQ when log-config filter/publisher objects are out of sync. This blocks configuration management and synchronization between BIG-IQ and BIG-IP devices.

Workaround:
None.

Fix:
Re-importing BIG-IP LTM devices now succeeds even when log-config filter/publisher objects are out of sync. The "not authenticated" error no longer occurs.

Fixed Versions:
8.4.2

2251889 : "dependsOn" property shown as changed for DNS A and AAAA Pool Members during configuration evaluation

Links to More Info: BT2251889

Component: BIG-IQ Local Traffic & Management

Symptoms:
During a configuration evaluation in BIG-IQ for DNS pool members (A and AAAA types), the system consistently reports a difference: the DNS device configuration includes 'dependsOn': [], whereas the BIG-IQ configuration omits the 'dependsOn' property. This leads to persistent false-positive configuration differences during evaluation and deployment.

Conditions:
-- DNS pool member (A or AAAA type) is imported from a DNS device into BIG-IQ
-- Pool member is modified or created in BIG-IQ and pushed to the DNS device
-- The process is performed using Configuration -> Evaluate & Deploy -> DNS in BIG-IQ

Impact:
The evaluation page consistently displays differences for pool members, causing confusion and making it difficult for users to identify actual configuration changes. This affects the reliability of BIG-IQ for managing DNS devices.

Workaround:
None.

Fix:
The transform logic for DNS pool member objects in BIG-IQ has been updated to create the 'dependsOn' property only when dependencies exist. Configuration evaluation now accurately reflects the state of pool members, eliminating false-positive differences.

Fixed Versions:
8.4.2


2251877 : BIG-IQ API assigns incorrect Utility license offering when multiple SKUs share substring names

Links to More Info: BT2251877

Component: BIG-IQ Device Management

Symptoms:
When assigning a Utility license offering via the BIG-IQ API, if multiple offerings have similar SKU names (e.g., one SKU is a substring of another), the API may assign the incorrect license. The system selects the first matching offering from the database, which may not be the intended SKU.

Conditions:
- License pool contains multiple offerings with similar SKU names (e.g., F5-BIG-MSP-A-LTM-12 and F5-BIG-MSP-A-LTM-12-R).
- License assignment is performed using the BIG-IQ API.
- The SKU keyword used in the API request matches more than one offering.

Impact:
The API may assign the wrong license offering, resulting in incorrect licensing of BIG-IP devices. This can affect automation and management workflows, especially for devices that are unreachable or managed only via API.

Workaround:
None

Fix:
The license assignment behavior has been updated to sort offerings by the "name" field in ascending order. This ensures that the shortest, most exact match is chosen when multiple SKUs share a substring name.

Fixed Versions:
8.4.2


2230133 : The QKView does not include elasticsearch.yml configuration file on BIG-IQ

Links to More Info: BT2230133

Component: BIG-IQ Device Management

Symptoms:
When generating a QKView on BIG-IQ, the resulting archive does not include the /var/config/rest/elasticsearch/config/elasticsearch.yml file, which is crucial for troubleshooting Elasticsearch-related issues.

Conditions:
-- QKView is generated on a BIG-IQ system running version 8.4.1.
-- The user extracts and examines the QKView archive.
-- The file /var/config/rest/elasticsearch/config/elasticsearch.yml is missing from the archive.

Impact:
Support and users are unable to review Elasticsearch configuration details from QKView, which can hinder troubleshooting and root cause analysis of Elasticsearch problems.

Workaround:
Manually collect the /var/config/rest/elasticsearch/config/elasticsearch.yml file from the BIG-IQ system and provide it to support as needed.

Fix:
QKView will include the /var/config/rest/elasticsearch/config/elasticsearch.yml file in the archive, allowing for complete Elasticsearch configuration review during troubleshooting.

Fixed Versions:
8.4.2

2228901 : BIG-IQ Upgrade to 8.4.1 Breaks Single-NIC Deployments, Resulting in UI Access Loss

Links to More Info: BT2228901

Component: REST Framework and TMOS Platform

Symptoms:
After upgrading BIG-IQ CM or DCD with a single network interface from version 8.4.0 to 8.4.1, the management user interface becomes inaccessible on the default port 443. During the post-upgrade reboot, the system automatically reconfigures itself into single-NIC mode, changing the HTTPS port to 8443 and creating a self IP configuration called self_1nic.

Conditions:
This issue occurs when ALL of the following conditions are met:
-- BIG-IQ system (CM or DCD) has only one network interface (single-NIC configuration)
-- Upgrading from BIG-IQ version 8.4.0 to version 8.4.1
-- The system database variable provision.1nic is set to a non-forced value ("enable" or "disable") before upgrade

Impact:
-- Management UI becomes inaccessible at the expected port 443 (port changes to 8443)
-- Production systems require manual intervention to restore functionality

Workaround:
Force-disable single-NIC auto-detection before initiating the upgrade:

tmsh modify sys db provision.1nic value forced_disable

Fix:
The upgrade process now preserves the provision.1nic setting, preventing incorrect reconfiguration of single-NIC systems. Web UI and device discovery/import function as expected after upgrade.

Fixed Versions:
8.4.2


2228837-9 : System Integrity Status: Unavailable on BIG-IP versions with the fix for ID2141205

-- iSeries appliances
-- VIPRION B44xx blades (B4450, B4460)

This may occur when running the follow BIG-IP versions which include the fix for ID 2141205 (https://cdn.f5.com/product/bugtracker/ID2141205.html):
-- Pre-release versions of BIG-IP; specifically, sustaining branches for BIG-IP v21.0.x, v17.5.x and v17.1.x.
-- Engineering Hotfixes which include the fix for ID 2141205. To date, such Engineering Hotfixes have been provided for the following BIG-IP versions:
   -- v17.5.1.3, v17.5.1.4
   -- v17.1.0.1, v17.1.2.2, v17.1.3

Impact:
You are unable to determine the integrity of the system boot components validated by the Trusted Platform Module (TPM). The system integrity status shows Unavailable, when the actual status may be either Valid or Invalid.

Workaround:
None.

Fix:
Trusted Platform Module (TPM) status shows the correct system integrity status for BIG-IP versions which include the fix for ID2141205. ID2141205 is also resolved in BIG-IP releases and Engineering Hotfixes.

2186153-5 : CVE-2025-8194 cpython: Cpython infinite loop when parsing a tarfile

Component: REST Framework and TMOS Platform

Symptoms:
A flaw was found in the Python tarfile module. Processing a specially crafted tar archive, specifically an archive with negative offsets, can cause an infinite loop and deadlock. This issue results in a denial of service in the Python application using the tarfile module.

Conditions:
The application uses the Python tarfile module to process an attacker-supplied malicious tar archive containing negative offsets.

Impact:
It can cause an infinite loop leading to application hang or denial of service.

2162989 : BIG-IQ CM is unable to request full cert bundle from Venafi

Component: REST Framework and TMOS Platform

Symptoms:
Currently, when BIG-IQ sends the certificate retrieval request to Venafi, it does not send 'includeChain=true'. Thus, BIG-IQ does not get the full chain bundle of certs(leaf, intermediate, root). BIG-IQ gets only the leaf cert, and the leaf cert is imported into BIG-IQ.

Conditions:
This occurs when BIG-IQ creates the Venafi-signed certificate and retrieves the certificate from Venafi.

Impact:
BIG-IQ has the leaf certificate only instead of the full bundle(leaf, intermediate, root), and the same is deployed to BIG-IP ssl profiles. When the completed bundle is not available, ssl hand sake fails.

Fix:
Now BIG-IQ is able to retrieve the full bundle(leaf, intermediate, root) from Venafi and is able to deploy on BIG-IP.

Fixed Versions:

2014237-2 : CVE-2022-29154: rsync client path validation issue may allow overwrite of arbitrary files in target directory

Component: REST Framework and TMOS Platform

Symptoms:
An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file).

Conditions:
NA

Impact:
Potential overwrite of arbitrary files within the rsync target directory tree, which may lead to further exploitation.

Workaround:
NA

Fix:
This issue is addressed by the rsync update/patch included with the associated TMOS fix (see internal BIG-IP bug 1937381 and patch attachment 253673).

1923997-9 : CVE-2023-1668-openvswitch: ip proto 0 triggers incorrect handling

Component: REST Framework and TMOS Platform

Symptoms:
A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.

Conditions:
NA

Impact:
It can cause incorrect handling or misrouting of other IP packets, potentially leading to traffic disruption or denial of service.

Workaround:
NA

Fix:
The denial of service issue has been resolved in the package.

Fixed Versions:
8.4.1


1923817-8 : CVE-2017-11499: Constant Hashtable Seeds vulnerability (NodeJS v6.9.1)

Component: REST Framework and TMOS Platform

Symptoms:
Node.js v4.0 through v4.8.3, all versions of v5.x, v6.0 through v6.11.0, v7.0 through v7.10.0, and v8.0 through v8.1.3 was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup.

Conditions:
NA

Impact:
It can cause high CPU usage and event loop blocking, leading to a remote denial of service.

Workaround:
NA

Fix:
Hash flooding remote DoS issue has been resolved in the package.

Fixed Versions:
8.4.1


1923657-9 : CVE-2022-41858 kernel: null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip

Conditions:
A vulnerable Linux kernel where the SLIP network driver is enabled and a detach operation occurs during sl_tx_timeout().

Impact:
It can trigger a kernel crash (denial of service) and potentially leak kernel memory information.

Workaround:
Upgrade to a Linux kernel version that includes the SLIP driver fix or disable the SLIP driver if it is not required.

Fix:
patch has been applied

Fixed Versions:
8.4.2

1069949-5 : CVE-2018-1000007 curl: HTTP authentication leak in redirects

Component: REST Framework and TMOS Platform

Symptoms:
libcurl might accidentally leak authentication data to third parties.

When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value.

Sending the same set of headers to subsequent hosts is, in particular, a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy-sensitive information or data that could allow others to impersonate the libcurl-using client's request.

Conditions:
NA

Impact:
Sensitive information could be disclosed to an unauthorised user

Workaround:
NA

Fix:
Patched curl to fix the vulnerability.

1696741-1 : Error: ha-quorum: Username and/or password is incorrect

Links to More Info: BT1696741

Component: REST Framework and TMOS Platform

Symptoms:
Setting up automatic HA failover returns an error similar to the following:

An error occurred while adding the BIG-IQ: Error: ha-secondary: Username and/or password is incorrect Error: ha-quorum: Username and/or password is incorrect Error: ha-primary: Username and/or password is incorrect

Restjavad log on primary CM would have an entry similar to the following:

[WARN][01 Jan 2024 01:00:00 UTC][/shared/ha/add-peer-task/abcdefgh-1234-abcd-1234-abcdefghijkl/worker AddPeerTaskWorker] [/bin/bash, -c, /usr/bin/ha_corosync_config.sh -p <primary_discovery_ip> -s <secondary_discovery_ip> -q <quorum_discovery_ip> -r primary -a <floating_ip> -m] failed with exit code 1, stdout: haclient:x:189:hacluster, stderr: Error: ha-quorum: Username and/or password is incorrect
Error: ha-secondary: Username and/or password is incorrect
Error: ha-primary: Username and/or password is incorrect

Conditions:
- BIG-IQ CMs and DCD (Quorum) are configured to remotely authenticate (eg. TACACS+) users for CLI access.

Impact:
The user 'hacluster' could not be authenticated remotely, hence the HA autofailover setup task fails.

Workaround:
If the issue has already occurred, the cluster would need to be rebuilt by running the following on the primary and secondary CMs and on DCDs:

ha_reset -f <device local discovery IP>
reset-data-collection-cluster

Add 'hacluster' user in the CMs and Quorum DCD's /config/bigip/auth/localusers. Note that this will not survive reboots.

Add at least one DCD into the cluster that will be used as quorum device, then configure the autofailover HA.

Use the guide in https://my.f5.com/manage/s/article/K11948 for creating a script that would add hacluster user into /config/bigip/auth/localusers everytime that the CMs and Quorum device reboot.

1316593-2 : An error occurs when importing an ASM Policy containing the same URLs but with different HTTP request methods

Component: BIG-IQ Web Application Security (ASM)

Symptoms:
BIG-IQ restjavad log file would show an error similar to the following when importing configuration from a BIG-IP ASM device:

[/cm/asm/tasks/discover-config/4e3b4176-308e-4591-8468-4ef9719efdc2/worker AsmDiscoveryTaskWorker] Error while creating 'ASM Policy - Url' 'null' in current-config: http://localhost:8100/cm/asm/current-config/policies/343a57d0-1c6f-36f0-b0a9-fb4647bbe1d5/urls, and while creating 'ASM Policy - Url' 'null' in current-config: http://localhost:8100/cm/asm/current-config/policies/343a57d0-1c6f-36f0-b0a9-fb4647bbe1d5/urls, and while creating 'ASM Policy - Url' 'null' in current-config: http://localhost:8100/cm/asm/current-config/policies/343a57d0-1c6f-36f0-b0a9-fb4647bbe1d5/urls, and while creating 'ASM Policy - Url' 'null' in current-config: http://localhost:8100/cm/asm/current-config/policies/343a57d0-1c6f-36f0-b0a9-fb4647bbe1d5/urls : java.lang.IllegalArgumentException: Duplicate item. Key already exists: protocol : http, name : /test/duplicateUrl

In this example, inspecting the affected ASM policy from the BIG-IP ASM that is being imported should reveal that one of the affected URLs would have multiple allowed URL entries for "/test/duplicateUrl", but those entries would have different HTTP request methods.

Conditions:
- Multiple entries in the ASM policy for the same URL but with different HTTP request methods.

Impact:
Unable to import ASM policy configuration from the BIG-IP ASM device.

Workaround:
The feature for having multiple entries for the same allowed URLs having different HTTP request methods is not yet implemented for BIG-IQ v8.3.0.

Avoid using multiple entries for the same allowed URLs.

If the feature is absolutely necessary, install an EHF for ID1316593.
