Detailsinfo

A vulnerability was found in Sun Solaris 2.7/2.8 (Operating System). It has been rated as problematic. Affected by this issue is some unknown functionality of the component catman. The manipulation of the argument sman_PID with an unknown input leads to a symlink vulnerability. Using CWE to declare the problem leads to CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. Impacted is integrity. CVE summarizes:

catman in Solaris 2.7 and 2.8 allows local users to overwrite arbitrary files via a symlink attack on the sman_PID temporary file.

The bug was discovered 12/18/2000. The weakness was shared 12/18/2000 by Larry W. Cashdollar as confirmed posting (Bugtraq). The advisory is shared for download at archives.neohapsis.com. This vulnerability is handled as CVE-2001-0095. The exploitation is known to be difficult. The attack needs to be approached locally. No form of authentication is required for exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed by Shane Hird in Perl and been published immediately after the advisory. The exploit is available at archives.neohapsis.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.
