Description

SATAN contains a flaw that allows local attackers to overwrite arbitrary files and possibly gain root priveleges. The flaw is due to a lack of sanity checking on calls to temporary files created in /tmp that do not check for existing files with the same name. Such flaws can be taken advantage of with symlinks and arbitrary files can be overwritten or appended to.

Classification

Location: Local Access Required
Attack Type: Race Condition

Technical

The file bin/rex.satan contains the vulnerability.

Solution

Due to the fact SATAN has not been upgraded and the last version available is still vulnerable, administrators should use other freeware alternatives such as SAINT.
