Detailsinfo

A vulnerability, which was classified as very critical, has been found in Imatix Xitami 2.5c2. This issue affects the function sendfmt of the file shtm. 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. The summary by CVE is:

Multiple format string vulnerabilities in the SSI filter in Xitami Web Server 2.5c2, and possibly other versions, allow remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via format string specifiers in a URI that ends in (1) .ssi, (2) .shtm, or (3) .shtml, which triggers incorrect logging code involving the sendfmt function in the SMT kernel.

The weakness was disclosed 03/25/2009 by bratax (Website). The advisory is shared at xforce.iss.net. The identification of this vulnerability is CVE-2008-6520 since 03/25/2009. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/03/2018).

A public exploit has been developed in C++. The exploit is available at securityfocus.com. It is declared as proof-of-concept. By approaching the search of inurl:shtm it is possible to find vulnerable targets with Google Hacking.

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

The vulnerability is also documented in the databases at X-Force (41645) and SecurityFocus (BID 28603†). The entry VDB-47296 is pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
