[GLSA-200412-01] rssh, scponly: Unrestricted command execution Vulnerability Scan
Vulnerability Scan Summary
rssh, scponly: Unrestricted command execution
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200412-01
(rssh, scponly: Unrestricted command execution)
Jason Wies discovered that when receiving an authorized command from an
authorized user, rssh and scponly do not filter command-line options
that can be used to execute any command on the target host.
Impact
Using a malicious command, it is possible for a remote authenticated
user to execute any command (or upload and execute any file) on the
target machine with user rights, effectively bypassing any restriction
of scponly or rssh.
Workaround
There is no known workaround at this time.
