Impact

The pool-upgrade request handler in Indy-Node <=1.12.4 allows an improperly authenticated attacker to remotely execute code on nodes within the network.

Network operators are strongly encouraged to upgrade to the latest Indy-Node release >=1.12.5 as soon as possible.

Patches

The pool-upgrade request handler in Indy-Node >=1.12.5 has been updated to properly authenticate pool-upgrade transactions before any processing is performed by the request handler. The transactions are further sanitized to prevent remote code execution.

Mitigations

Network operators are strongly encouraged to upgrade to the latest Indy-Node release >=1.12.5 as soon as possible.
