A vulnerability was found in IBM AIX 5.2/5.3 (Operating System). It has been classified as critical. Affected is some unknown functionality of the component swcons. The manipulation with an unknown input leads to a link following vulnerability. CWE is classifying the issue as CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
cfgcon in IBM AIX 5.2 and 5.3 does not properly validate the argument to the "-p" option to swcons, which allows local users in the system group to create an arbitrary file, and enable world writability of this file, via a symlink attack involving use of the file s name as the argument. NOTE: this issue is due to an incomplete fix for CVE-2007-5804.
