Summary
The LDAP implementation on the Cisco Web Security Appliance (WSA) 8.5.0-000, Email Security Appliance (ESA) 8.5.7-042, and Content Security Management Appliance (SMA) 8.3.6-048 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate, aka Bug IDs CSCuo29561, CSCuv40466, and CSCuv40470.
Exploit prediction
0.48% chance of exploitation in the next 30 days, higher than 41% of all scored CVEs (FIRST EPSS, 2026-11-09).
