CVE-2011-5117
CWE-362Published: August 24, 2012· Updated: Jun 16, 2026
6.9
CVSS v3.1
Official Description
Sophos SafeGuard Enterprise Device Encryption 5.x through 5.50.8.13, Sophos SafeGuard Easy Device Encryption Client 5.50.x, and Sophos Disk Encryption 5.50.x have a delay before removal of (1) out-of-date credentials and (2) invalid credentials, which allows physically proximate attackers to defeat the full-disk encryption feature by leveraging knowledge of these credentials.
Technical Analysis
CVE-2011-5117 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
