  • The SQL injection is delivered via HTTP POST to the /api/login URI endpoint of the BIG-IP Next Central Manager API; detection should focus on POST requests to this path containing a JSON body with a 'provider_name' key.
  • The injected payload in the provider_name JSON field contains classic SQL injection keywords: SELECT FROM, UNION SELECT, INSERT INTO, DELETE FROM, UPDATE SET, SHOW TABLES/VARIABLES/CHARACTER SET, and inline comment sequences (/* ... */).
  • Successful exploitation allows unauthenticated remote attackers to gain full administrative control of the BIG-IP Next Central Manager and create rogue accounts on managed BIG-IP Next assets that are not visible from the Central Manager UI — monitor for unexpected admin account creation on managed assets.
  • The vulnerability is exploitable via the administrative UI; restrict Next Central Manager management interface access to trusted users over a secure network as a temporary mitigation.
  • Over 10,000 F5 BIG-IP devices with management ports exposed online are tracked by Shodan — use this as a hunting pivot to identify exposed instances.
  • ·Only BIG-IP Next Central Manager versions 20.0.1 through 20.2.0 are affected; software versions that have reached End of Technical Support (EoTS) are not evaluated.
  • ·The Snort/Suricata rule (ET sid:2056183) is scoped to plaintext (non-TLS) traffic only; encrypted management traffic will not be detected by this signature.
  • ·At time of disclosure, there was no evidence of in-the-wild exploitation of CVE-2024-26026, though a public proof-of-concept exploit was released by Eclypsium.
