Cosign 2.0.1/2.9.4a - CGI Register Command Remote Authentication Bypass
source: https://www.securityfocus.com/bid/23424/info
The 'cosign' application is prone to an authentication-bypass vulnerability because it fails to adequately sanitize user-supplied input.
An authenticated attacker can exploit this issue to access services hosted on an affected computer by assuming another user's credentials.
Versions prior to 1.9.4b and 2.0.2a are vulnerable.
