Secure testing team - Oct 2011 - Bug#647205: cherokee: Admin password generation uses time and PID, allows attackers to brute-force it

Package: cherokee
Version: 1.2.100-1
Severity: grave
Tags: security
Justification: user security hole

CVE issue CVE-2011-2190 points out that the temporary admin password
generation function is seeded by the time and PID, which allows an
attacker to brute-force it. Yes, in production systems cherokee-admin
should be quite short-lived, but administrators can leave it running
for long periods, opening a window to this attack.
