Vulnerability from fkie_nvd - Published: 2026-09-30 10:17 - Updated: 2026-09-30 16:13
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
Summary
Improper input validation in sshd-git in Apache MINA SSHD, versions up to 2.19.0 and 3.0.0-M1 to 3.0.0-M5. Apache MINA SSHD is a Java library for client-side and server-side SSH. Component org.apache.sshd:sshd-git provides though class GitPgmCommandFactory a way to configure an Apache MINA SSHD server such that authenticated SSH clients can remotely execute git commands via the JGit library on git repositories stored on the server. In CVE-2026-58624 this mechanism was restricted to only a few git commands, including "git archive" without "--output" or "-o" options such that the resulting archive would not be written on the server but instead sent back to the client over the SSH connection. The fix done for CVE-2026-58624 was insufficient as it missed removing the single-argument "-o=file.zip" version of the command parameter from the "archive" command. Users are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.
