An issue was discovered in Honeywell XL Web II controller XL1000C500 XLWebExe-2-01-00 and prior, and XLWeb 500 XLWebExe-1-02-08 and prior. An attacker can establish a new user session, without invalidating any existing session identifier, which gives the opportunity to steal authenticated sessions (SESSION FIXATION).
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

| Xl_web_ii_controller | Honeywell | xlwebexe-2-01-00 (including) | xlwebexe-2-01-00 (including) |
Such a scenario is commonly observed when:
In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
