Discussion

Allaire JRun Duplicate Session ID Vulnerability

Allaire JRun is a web application development suite.

A flaw exists in the JRun session management which could allow an attacker to take actions on the host with privileges of a logged in user.

When a user visits a web application based on JRun, they are given a session id.
By not requesting a trailing '/' character after the web application directory (ie, requesting http://host/application), JRun will provide the requester with session ID that has been set for another client.

Session IDs are relied upon to be unique and non-guessable, assigned once to each web browser per session. Many applications assign them to authenticated users, later using them to authorize actions.

Depending on the application, the user may be able to perform actions as other users or otherwise violate security if they gain the session ID of another client.
