CyberRota Analysis
AI-GeneratedSSHFS versions 1.4 to 3.7.6 are vulnerable to arbitrary command execution due to improper handling of bracketed mount sources, which allows an attacker to inject commands that execute locally before authentication. This vulnerability poses a significant risk to users running SSHFS, particularly in environments where untrusted input may be passed to the filesystem client. Organizations utilizing affected versions should prioritize upgrading to version 3.7.6 or later to mitigate this high-severity risk.

Original NVD Description
SSHFS is a network filesystem client for connecting to SSH servers. From version 1.4 until 3.7.6, SSHFS accepts a bracketed mount source such as [-oProxyCommand=CMD]:/path and find_base_path() removes the brackets, leaving a host value that begins with - and is passed directly to ssh as a command-line argument. When a caller also supplies a path-valued sftp_server, ssh treats the normalized host as an option and the server path as its destination, causing an injected ProxyCommand to execute locally before any connection or authentication succeeds. The attack requires a caller or wrapper that passes an attacker-controlled mount source to SSHFS with the required sftp_server configuration and results in arbitrary command execution as the user running SSHFS. This issue is fixed in version 3.7.6.
