A vulnerability was found in IBM Informix Extended Parallel Server up to 9.40.x (Information Management Software). It has been classified as problematic. This affects an unknown code block of the file 001. The manipulation with an unknown input leads to a symlink vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

IBM Informix Dynamic Server (IDS) before 9.40.xC3 allows local users to (1) create or overwrite files via the /001 log file to onedcu or (2) read arbitrary files via a symlink attack on a file in /tmp to onshowaudit.

The weakness was disclosed 01/18/2004 as not defined posting (Bugtraq). The advisory is shared at securityfocus.com. This vulnerability is uniquely identified as CVE-2004-2319 since 08/16/2005. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in Shell File. The exploit is shared for download at securityfocus.com. It is declared as highly functional. We expect the 0-day to have been worth approximately $5k-$25k.

Upgrading to version 9.40.xc3 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (14971). The entries 21514, 23374, 23373 and 81935 are pretty similar.
