Security Advisory

1) Denial of service

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to an error when processing malicious user-supplied data. A remote attacker can send specially crafted URL data to an application that accepts a user-provided URL in a form field and that processes the URL with the built-in URLValidator to overload the server process during validation.

Successful exploitation of the vulnerability results in denial of service.

Remediation

Update to version 2.5.12.
