Detailsinfo

A vulnerability classified as critical has been found in SCO OpenServer 5.0.5/5.0.6/5.0.6a (Operating System). Affected is the function getdbm of the file /var/yp of the component ypxfrd. 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. CVE summarizes:

The getdbm procedure in ypxfrd allows local users to read arbitrary files, and remote attackers to read databases outside /var/yp, via a directory traversal and symlink attack on the domain and map arguments.

The bug was discovered 10/07/2002. The weakness was presented 10/28/2002 by Janusz Niewiadomski with isec.pl as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is traded as CVE-2002-1199. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 21 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 10244 , which helps to determine the existence of the flaw in a target environment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
