Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Atos Unify OpenScape 4000 Assistant and Manager versions prior to V10 R1.42.0 and V10 R1.34.8 contain a command injection vulnerability allowing authenticated users to execute arbitrary operating system commands, likely through insufficient input validation in web interface parameters.
