Vigil@nce - Apache Subversion: information disclosure via MD5 Cache
August 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can trigger a MD5 collision in the cache of
Apache Subversion, in order to obtain sensitive information.
Impacted products: Subversion, openSUSE, Ubuntu
Severity: 1/4
Creation date: 26/08/2014
DESCRIPTION OF THE VULNERABILITY
The Apache Subversion caches user’s credentials. These credentials
are stored in a tree indexed by the result of a MD5 hash.
However, an attacker may trigger a MD5 collision, in order to
obtain data belonging to another user.
A local attacker can therefore trigger a MD5 collision in the
cache of Apache Subversion, in order to obtain sensitive
information.
