GLSA-200412-01 : rssh, scponly: Unrestricted command execution

high Nessus Plugin ID 15903

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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.

Solution

All scponly users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/scponly-4.0' All rssh users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-shells/rssh/rssh-2.2.3'
