EUVDB-ID: #VU32573

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0032

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The get_resource function in repos.c in the mod_dav_svn module in Apache Subversion before 1.7.15 and 1.8.x before 1.8.6, when SVNListParentPath is enabled, allows remote attackers to cause a denial of service (crash) via vectors related to the server root and request methods other than GET, as demonstrated by the "svn ls http://svn.example.com" command.

Mitigation

Install update from vendor's website.
