A session fixation vulnerability in the B. Braun Melsungen AG SpaceCom administrative interface Version L81/U61 and earlier, and the Data module compactplus Versions A10 and A11 allows remote attackers to hijack web sessions and escalate privileges.
Weakness
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.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Datamodule_compactplus | Bbraun | a10 (including) | a10 (including) |
| Datamodule_compactplus | Bbraun | a11 (including) | a11 (including) |
Extended Description
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.
