Root command execution via unsanitized TFTP address
Published Jan 17, 2024 · Updated Jun 2, 2025
Command injection in Cisco Business Wireless Access Point Software 1.3.0.7 and earlier allows remote authenticated users to execute root commands. The WAP371 packet-capture handler concatenates the administrator-supplied TFTP server address directly into a Linux tftp shell command without sanitization. Valid administrative credentials and network access to the WebUI are required; injected delimiters run attacker-chosen commands as the cisco user, which is equivalent to root.
