GNU Wget SSL Certificate Security Bypass

medium Nessus Network Monitor Plugin ID 5212
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host is affected by a security bypass vulnerability.


The remote host is using a version of Wget earlier than 1.12. Such versions are potentially affected by a security bypass vulnerability because the application fails to properly handle Common Name fields n X.509 certificates that contain an ASCII NULL character.


Upgrade to Wget 1.12 or later.
