Vulnerability from github – Published: 2025-10-07 15:30 – Updated: 2025-10-08 15:32

Details

Clash Verge Rev thru 2.2.3 forces the installation of system services(clash-verge-service) by default and exposes key functions through the unauthorized HTTP API /start_clash, allowing local users to submit arbitrary bin_path parameters and pass them directly to the service process for execution, resulting in local privilege escalation.

Severity

7.8 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
