Lifecycle Timeline
4DescriptionGitHub Advisory
ZAI Shell is an autonomous SysOps agent designed to navigate, repair, and secure complex environments. Prior to 9.0.3, the P2P terminal sharing feature (share start) opens a TCP socket on port 5757 without any authentication mechanism. Any remote attacker can connect to this port using a simple socket script. An attacker who connects to a ZAI-Shell P2P session running in --no-ai mode can send arbitrary system commands. If the host user approves the command without reviewing its contents, the command executes directly with the user's privileges, bypassing all Sentinel safety checks. This vulnerability is fixed in 9.0.3.
AnalysisAI
Unauthenticated remote code execution in Zai Shell prior to 9.0.3 via the unprotected P2P terminal sharing feature on port 5757, where attackers can inject arbitrary system commands that execute with user privileges if approved. Public exploit code exists for this vulnerability, and affected systems running --no-ai mode completely bypass safety checks during command execution. …
