Detailsinfo

A vulnerability was found in Oracle Application Server 9.0.2 (Application Server Software). It has been rated as critical. Affected by this issue is the function dav_lookup_uri of the file mod_dav.c of the component 502 Bad Gateway Response Handler. The manipulation with an unknown input leads to a format string vulnerability. Using CWE to declare the problem leads to CWE-134. The product uses a function that accepts a format string as an argument, but the format string originates from an external source. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Format string vulnerability in certain third party modifications to mod_dav for logging bad gateway messages (e.g. Oracle9i Application Server 9.0.2) allows remote attackers to execute arbitrary code via a destination URI that forces a "502 Bad Gateway" response, which causes the format string specifiers to be returned from dav_lookup_uri() in mod_dav.c, which is then used in a call to ap_log_rerror().

The weakness was published 03/03/2003 by David Litchfield as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is handled as CVE-2002-0842. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.
