Routine

LOW 1.9WATCHLISTDOWNGRADEMITIGATE

CVE-2006-6614 is a low-severity flaw (CVSS 1.9) affecting fully automated installation, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The save_log_local function in Fully Automatic Installation (FAI) 2.10.1, and possibly 3.1.2, when verbose mode is enabled, stores the root password hash in /var/log/fai/current/fai.log, whose file permissions allow it to be copied to other hosts when fai-savelog is called and allows attackers to obtain the hash.
