Name of the Vulnerable Software and Affected Versions: mymbCONNECT24 and mbCONNECT24 versions through V2.6.2

Description: The issue is related to improper use of access validation, allowing a logged-in user to kill web2go sessions in an account they should not have access to. This is due to insecure privilege management, which can be exploited by a remote attacker to terminate web2go sessions in unauthorized accounts.

Recommendations: For versions through V2.6.2, consider restricting access to the web2go session management functionality until a patch is available. As a temporary workaround, limit the privileges of logged-in users to prevent them from accessing accounts they should not have access to.
