Title: HP-UX login btmp Logging Failure Vulnerability
Severity: MODERATE
Description:
The version of 'login' shipped with HP-UX 10.26 does not record unsuccessful login attempts in 'btmp'. The btmp file is used to record bad logins.
It may be possible for attackers to launch a brute force attack that is not noticed by administrators who rely on btmp. As unsuccessful logins would not be recorded in the file, administrators using 'lastb' to view recent bad login attempts would not notice the attacker's attempts.
The attempts may still be visible in other logs (such as syslog).
Affected Products:
- HP HP-UX 10.26.0
