The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. The summary by CVE is:

Apt 0.8.16~exp5ubuntu13.x before 0.8.16~exp5ubuntu13.6, 0.8.16~exp12ubuntu10.x before 0.8.16~exp12ubuntu10.7, and 0.9.7.5ubuntu5.x before 0.9.7.5ubuntu5.2, as used in Ubuntu, uses world-readable permissions for /var/log/apt/term.log, which allows local users to obtain sensitive shell information by reading the log file.

The bug was discovered 04/06/2012. The weakness was shared 12/12/2012 by James Troup with Ubuntu as Bug #975199 as not defined feature request (Website). The advisory is shared at bugs.launchpad.net. The vendor cooperated in the coordination of the public release. The identification of this vulnerability is CVE-2012-0961 since 02/01/2012. An attack has to be approached locally. The successful exploitation needs a simple authentication. Technical details as well as a public exploit are known. MITRE ATT&CK project uses the attack technique T1592 for this issue.

After immediately, there has been an exploit disclosed. The exploit is available at packetstormsecurity.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 250 days. During that time the estimated underground price was around $0-$5k. By approaching the search of inurl:var/log/apt/term.log it is possible to find vulnerable targets with Google Hacking. The vulnerability scanner Nessus provides a plugin with the ID 63260 (Ubuntu 11.10 / 12.04 LTS / 12.10 : apt vulnerability (USN-1662-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks.

Applying a patch is able to eliminate this problem.

The vulnerability is also documented in the databases at X-Force (80785), Tenable (63260), SecurityFocus (BID 56917†), OSVDB (88380†) and Secunia (SA51568†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
