Title

CyberPanel before 3.0.5 Authentication Bypass via API

Summary

CyberPanel before 3.0.5 fails to enforce two-factor authentication on API endpoints, allowing attackers to bypass TOTP requirements using password-derived tokens. Attackers who obtain an administrator's password can derive API tokens and perform administrative operations or create authenticated sessions without the second factor.

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.
