CVE-2014-8937Public exploitNetwork attack vector

Unauthenticated service interruption via resource-intensive updates

Published Jun 1, 2020 · Updated Aug 6, 2024

Uncontrolled resource consumption in Lexiglot through 2014-11-20 allows remote attackers to interrupt service through the update API. The api/update.php endpoint launches a Subversion update operation whose execution consumes substantial server resources. Unauthenticated network access is sufficient, and repeated requests exhaust resources without reported data disclosure or modification.
