CVE-2023-51385: , CVE-2023-6004: OpenSSH, libssh: Security weakness in ProxyCommand handling
First published: Mon Dec 18 2023(Updated: )
In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.
