Detailsinfo

A vulnerability was found in Microsoft Visual Studio 6 (Programming Tool Software) and classified as critical. Affected by this issue is an unknown code of the file PDWizard.ocx of the component ActiveX Control. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Absolute directory traversal vulnerability in a certain ActiveX control in the VB To VSI Support Library (VBTOVSI.DLL) 1.0.0.0 in Microsoft Visual Studio 6.0 allows remote attackers to create or overwrite arbitrary files via a full pathname in the argument to the SaveAs method. NOTE: contents can be copied from local files via the Load method.

The weakness was presented 09/14/2007 by shinnai (Website). The advisory is shared for download at shinnai.altervista.org. This vulnerability is handled as CVE-2007-4890 since 09/13/2007. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. Technical details as well as a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1006.

A public exploit has been developed by shinnai and been published even before and not after the advisory. The exploit is available at shinnai.altervista.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $5k-$25k.

The best possible mitigation is suggested to be disabling the affected component. Attack attempts may be identified with Snort ID 12462. In this case the pattern 7|00|E|00|E|00|A|00|3|00|9|00|E|00|3|00|-|00|4|00|1|00|D|00|1|00|-|00|1|00|1|00|D|00|2|00|-|00|A|00|B|00|3|00|B|00|-|00|0|00|0|00|A|00|A|00|0|00|0|00|B|00|D|00|D|00|6|00|8|00|5|00| is used for detection.

The vulnerability is also documented in the databases at X-Force (36571), Exploit-DB (4394), SecurityFocus (BID 25635†), OSVDB (37107†) and Secunia (SA26779†). See VDB-3309 and VDB-38782 for similar entries. Once again VulDB remains the best source for vulnerability data.
