A vulnerability was found in Subversion 1.0/1.0.1/1.0.2. It has been declared as critical. This vulnerability affects the function sscanf. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow during the apr_time_t data conversion in Subversion 1.0.2 and earlier allows remote attackers to execute arbitrary code via a (1) DAV2 REPORT query or (2) get-dated-rev svn-protocol command.

The weakness was shared 05/19/2004 by Stefan Esser with eMatters (Website). The advisory is shared for download at subversion.tigris.org. This vulnerability was named CVE-2004-0397 since 04/13/2004. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known.

It is possible to download the exploit at immunitysec.com. It is declared as highly functional. The vulnerability scanner Nessus provides a plugin with the ID 14500 (GLSA-200405-14 : Buffer overflow in Subversion), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 1 days after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 14601. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 2872.
