HTTP: Webmin Fake SessionID Initialization
This signature detects attempts to exploit a known vulnerability in Webmin. Webmin versions 1.050 to 1.060 are vulnerable. Attackers can send a maliciously crafted GET request to a Webmin server to bypass authorization for the Webmin interface and perform system administration tasks (such as adding and deleting users).
Extended Description
A vulnerability has been discovered in the 'Miniserv.pl' script used to invoke both Webmin and Usermin. Due to insufficient sanitization of client-supplied BASE64 encoded input, it is possible to inject a Session ID into the access control list. Successful exploitation of this vulnerability may allow an attacker to bypass typical authentication procedures, thus gaining adminstrative access to a webmin/usermin interface.
