SOL14733: Apache HTTP server vulnerability CVE-2013-1896

Security AdvisorySecurity Advisory

Original Publication Date: 10/04/2013


mod_dav.c in the Apache HTTP Server before 2.2.25 does not properly determine 
whether DAV is enabled for a URI, which allows remote attackers to cause a 
denial of service (segmentation fault) via a MERGE request in which the URI 
is configured for handling by the mod_dav_svn module, but a certain href 
attribute in XML data refers to a non-DAV URI.


Denial-of-service (DoS) for the ARX management API.
