CVE-2022-41622: F5 BIG-IP and BIG-IQ iControl SOAP CSRF flaw

F5 · Big Iq Centralized Management

BIG-IP and BIG-IQ are vulnerable to cross-site request forgery through the iControl SOAP interface across all versions, per the vendor description. Because the interface is reachable over the network and the flaw allows state-changing requests, it matters for any deployment exposing iControl SOAP.

Description

In all versions,  BIG-IP and BIG-IQ are vulnerable to cross-site request forgery (CSRF) attacks through iControl SOAP.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 18 September 2026. Confidence: medium.

high priorityCVSS 8.8 with no privileges required and a very high EPSS score, though exploitation requires user interaction and no KEV listing exists.

What it is

BIG-IP and BIG-IQ are vulnerable to cross-site request forgery through the iControl SOAP interface across all versions, per the vendor description. Because the interface is reachable over the network and the flaw allows state-changing requests, it matters for any deployment exposing iControl SOAP.

Impact

An attacker who lures a privileged user into a crafted request can trigger unauthorized actions through iControl SOAP with that user's privileges, affecting confidentiality, integrity and availability (CVSS 8.8).

Attack surface

Reached over the network via the iControl SOAP endpoint; the CVSS vector shows no privileges required but user interaction is required, so a victim with an active session must be induced to send the request.

Exploitation

Not listed in CISA KEV and no public exploit tags appear in the references, but EPSS is very high (0.9234, 99.8th percentile), indicating elevated predicted exploitation activity.

What to do

  • Apply the F5 vendor advisory K94221585 fixes for BIG-IP and BIG-IQ; note that EoTS versions are not evaluated and should be upgraded or retired.
  • Restrict network access to iControl SOAP to trusted management hosts and disable it where not needed.
  • Enforce same-site cookies and CSRF protections on management interfaces, and avoid browsing untrusted sites while authenticated to the management UI.
  • Monitor and alert on unexpected iControl SOAP configuration changes.

Detection

  • Audit iControl SOAP access logs for requests originating from unexpected client IPs or referers.
  • Alert on configuration or object changes made via iControl SOAP outside change windows.
  • Correlate management UI sessions with SOAP calls to spot cross-origin request patterns.

This assessment is produced automatically and is not human-reviewed. Verify against the vendor advisory before acting on it.
