CVE-2026-129120 C-Kermit 11.0.506 before 11.1.515 RECEIVE CONFIRM Bypass via Recursive GET

5.9 medium

Medium (5.9) in openkermit c-kermit.

On this page
C-Kermit 11.0.506 before 11.1.515 contains a RECEIVE CONFIRM bypass vulnerability that allows malicious Kermit servers to write unrequested files without prompting by abusing recursive GET root computation in ckcfns.c. Attackers can send files such as .ssh/authorized_keys or shell startup files under the current directory, which rq_under_root() accepts silently, enabling persistent access or code execution.
