CVE-2024-34713

sshproxy vulnerable to SSH option injection

Published May 14, 2024 CVSS 3.1 · 3.5 Low EPSS < 1% KEV · Not listed
Description
sshproxy is used on a gateway to transparently proxy a user SSH connection on the gateway to an internal host via SSH. Prior to version 1.6.3, any user authorized to connect to a ssh server using `sshproxy` can inject options to the `ssh` command executed by `sshproxy`. All versions of `sshproxy` are impacted. The problem is patched starting in version 1.6.3. The only workaround is to use the `force_command` option in `sshproxy.yaml`, but it's rarely relevant.
