Vigil@nce: WebSphere AS, SSL not used for SSO
February 2010 by Vigil@nce
SYNTHESIS OF THE VULNERABILITY
When the Single Sign-On authentication of WebSphere is configured to enforce SSL, the session does not use SSL.
Consequences: data reading, data creation/edition
Provenance: internet client
Means of attack: no proof of concept, no attack
Ability of attacker: expert (4/4)
Confidence: confirmed by the editor (5/5)
Diffusion of the vulnerable configuration: high (3/3)
Creation date: 08/02/2010
IBM WebSphere Application Server
DESCRIPTION OF THE VULNERABILITY
The Single Sign-On authentication of WebSphere can be configured
to enforce SSL:
WebSphere Application Server Administration Console
Web and SIP Security
Single Sign-on (SSO)
However, this directive is not honoured, so authentication data are not encrypted.
An attacker can therefore capture authentication data.
