description

OpenSpug Spug releases through 3.4.0 and 4.0.1 contain an OS command injection issue in the File Transfer endpoint. A remote attacker may be able to execute operating-system commands through that functionality; the required authentication or other access precondition is not documented.

mitigation

Disable the File Transfer feature or restrict access to its transfer endpoint to trusted administrative networks. Until a vendor-fixed release is available, prevent untrusted users from reaching this functionality.
