Memory disclosure via NTLM buffer over-read
Published Aug 4, 2022 · Updated Sep 16, 2024
Out-of-bounds read in F5 BIG-IP allows remote attackers to disclose adjacent memory via crafted traffic to an NTLM-enabled virtual server. The LTM monitor and APM SSO NTLM processing reads beyond a buffer boundary, but F5 has not disclosed the exact code locus or traffic form. Reachability requires either feature on a virtual server with NTLM challenge-response in use; the reported consequence is limited to unintended data disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=13.1.0 <13.1.x*
- Affected versionversion=14.1.x <14.1.5.1
- Affected versionversion=15.1.x <15.1.6.1
