Detailsinfo

A vulnerability was found in Apple CUPS up to 1.1.3 (Printing Software) and classified as problematic. This issue affects the function cgi_initialize_string. The manipulation of the argument admin?OP=redirect/URL= with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality. The summary by CVE is:

The cgi_initialize_string function in cgi-bin/var.c in the web interface in CUPS before 1.4.4, as used on Apple Mac OS X 10.5.8, Mac OS X 10.6 before 10.6.4, and other platforms, does not properly handle parameter values containing a % (percent) character without two subsequent hex characters, which allows context-dependent attackers to obtain sensitive information from cupsd process memory via a crafted request, as demonstrated by the (1) /admin?OP=redirect&URL=% and (2) /admin?URL=/admin/&OP=% URIs.

The weakness was shared 06/17/2010 by Kevin Finisterre (pagvac) with MIT Kerberos Team (Website). It is possible to read the advisory at lists.apple.com.
