DoS via Uninitialized Variable in mod_dav_svn (Subversion 1.7.0-1.7.8)

IdentifiersCVE-2013-1884CWE-457

CVE-2013-1884 is a denial of service vulnerability in the mod_dav_svn module of the Apache HTTPD server, as used by Subversion versions 1.7.0 through 1.7.8. The vulnerability is triggered when a remote attacker sends a log REPORT request with an invalid limit, causing the server to access an uninitialized variable, resulting in a segmentation fault and crash.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to crash the Apache HTTPD server hosting mod_dav_svn, leading to a denial of service condition. There is no indication of code execution or data compromise, but service availability is affected.

Mitigation

If you can’t patch tonight, do this now.

As a temporary mitigation, restrict access to the mod_dav_svn module to trusted users or networks, and monitor for abnormal REPORT requests. Consider disabling the module if it is not required until a patch can be applied.

Remediation

Patch, then assume compromise.

Upgrade Subversion to a version later than 1.7.8 where this issue has been patched. Ensure that all servers using mod_dav_svn are updated to the fixed version.
