BMC Server Automation rscd Service Authentication Bypass RCE
High Nessus Plugin ID 93686
SynopsisThe BMC Server Automation RSCD agent running on the remote host is affected by a remote command execution vulnerability.
DescriptionAccording to its self-reported version number, the BMC Server Automation (BSA) RSCD agent running on the remote host is affected by a remote command execution vulnerability due to a logic flaw in the authentication process of the rscd network daemon. An unauthenticated, remote attacker can exploit this issue to execute certain privileged commands without providing valid client certificates or credentials.
Specifically, one such command is REMOTE_COPY_DIRECTORY, which can be used to retrieve all files on the system with root privileges.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to BSA version 8.8 or later. Alternatively, apply version 8.7 Patch 3.
