CVE-2012-0814

• Severity: low (CVSS 3.5 v2.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 3.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2012-01-27 · updated 2026-06-16
• Weakness: CWE-255

Description

The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory.

Affected products

• OpenSSH: through 5.6; 1.2, 1.2.1, 1.2.2, 1.2.3, 1.2.27, 1.3 (+71)
