Actors can use a maliciously crafted JavaScript object notation (JSON) web token (JWT) to perform privilege escalation by submitting the malicious JWT to a vulnerable method exposed on the cloud platform. If the exploit is successful, the user can escalate privileges to access any device managed by the

ABUP Cloud Update Platform.
Fixes

Solution

ABUP did not respond to CISA's request for coordination. The vulnerable method has been removed by the vendor and is no longer accessible. Users of the cloud platform do not need to take any action. Legitimate users of the cloud update platform should be aware that there was a period of exposure that ended on 19 April 2025 and should consider modifying authentication information.


Workaround

No workaround given by the vendor.
