Description
A vulnerability was identified in zevorn rt-claw up to 0.2.0. This affects the function claw_net_get/claw_net_post of the file claw/tools/tool_net.c of the component http_request. Such manipulation of the argument url leads to server-side request forgery. The attack may be performed from remote. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.

AI Analysis

Impact

The vulnerability occurs in the http_request component of zevorn rt‑claw prior to version 0.2.0. Manipulating the URL argument passed to the claw_net_get or claw_net_post functions allows an attacker to force the server to issue arbitrary HTTP requests, which is a server‑side request forgery. Based on the description, it is inferred that an attacker could probe internal resources, exfiltrate data, or bypass network boundaries. The exploitation is remote and publicly available exploit code suggests an attacker could automate the attack.

Affected Systems

All installations of zevorn rt‑claw up to and including 0.2.0 are affected. The vulnerable code resides in claw/tools/tool_net.c and specifically in the claw_net_get/claw_net_post functions.

Risk and Exploitability

The CVSS score of 6.9 classifies the flaw as medium severity. The EPSS score of less than 1% suggests a low probability of exploitation in the wild at the time of analysis. The vulnerability is not listed in the CISA KEV catalog, further indicating limited known exploitation. Nevertheless, because the attack vector is remote and the public exploit code is available, system owners should assess whether the rt‑claw instance is exposed to untrusted input or network traffic before deciding on remediation measures.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply any available update from the zevorn rt‑claw repository or maintain a local fork with the fix applied, especially for versions up to 0.2.0.
  • Limit the outbound traffic of the rt‑claw service to only allow necessary external endpoints, blocking possible internal or internal network requests that could be abused via SSRF.
  • Implement strict validation and sanitization of the URL argument in the http_request functions, rejecting requests targeting private IP ranges or using disallowed protocols (e.g., file://).
