Name of the Vulnerable Software and Affected Versions
Xorbits Xoscar versions prior to 0.11.2
Description
An unauthenticated deserialization flaw exists in the actor-pool TCP channels. Remote attackers can execute arbitrary code with root privileges on GPU nodes by sending crafted data. The issue occurs when
SocketChannel.recv() passes unvalidated data to cloudpickle.loads(), triggering the execution of a pickle reduce gadget before the message type is validated.Recommendations
Update Xorbits Xoscar to a version newer than 0.11.2.
Fix
Deserialization of Untrusted Data
