CVE-2015-4288

Status: ModifiedMedium (4.3)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
