A vulnerability was found in Ubuntu installer 5.10. It has been declared as critical. This vulnerability affects an unknown part. The manipulation with an unknown input leads to a local privilege escalation vulnerability. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The Ubuntu 5.10 installer does not properly clear passwords from the installer log file (questions.dat), and leaves the log file with world-readable permissions, which allows local users to gain privileges.

The weakness was presented 03/13/2006 by Karl Øie (Website). The advisory is available at ubuntu.com. This vulnerability was named CVE-2006-1183. The exploitation appears to be easy. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Kristian Hermansen and been published even before and not after the advisory. It is possible to download the exploit at coresecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21069 (Ubuntu 5.10 : Ubuntu 5.10 installer vulnerability (USN-262-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks.

It is possible to mitigate the problem by adding an authentication mechanism.

The vulnerability is also documented in the databases at X-Force (25170), Exploit-DB (1579), Tenable (21069), SecurityFocus (BID 17086†) and OSVDB (23868†). Once again VulDB remains the best source for vulnerability data.
