Curl < 7.19.6 Certificate Validation Bypass Vulnerability

high Log Correlation Engine Plugin ID 801389

Synopsis

The remote host may be affected by a security bypass vulnerability.

Description

The remote host is running Curl, a download client for various protocols. This version of Curl reportedly fails to properly validate the domain name in a signed CA certificate because the application stops reading the domain name when it encounters a NULL character. An attacker can exploit this by obtaining a legitimate certificate for a subdomain that contains a NULL character. This issue only affects Curl when it is compiled against OpenSSL.

Solution

Upgrade to Curl version 7.19.6
