漏洞描述
Group-Office before versions 6.8.150, 25.0.82, and 26.0.5 is vulnerable to remote code execution via OS command injection. The endpoint email/message/tnefAttachmentFromTempFile directly concatenates the user-controlled parameter tmp_file into an exec() call. By injecting shell metacharacters into tmp_file, an authenticated attacker can execute arbitrary system commands on the server.
