Lifecycle Timeline
2DescriptionCVE.org
CyberPanel before 3.0.0 contains a path traversal vulnerability that allows authenticated administrators to read arbitrary files from the server filesystem by supplying unsanitized file paths to the cloudAPI ReadReport endpoint. Attackers can manipulate the reportFile parameter in the JSON request body, which is passed directly to open() in cloudManager.py without validation or allowlisting, enabling traversal to any file readable by the root-privileged CyberPanel process including credential files, SSL and SSH private keys, and JWT secret files.
AnalysisAI
CyberPanel versions before 3.0.0 expose a path traversal in the cloudAPI ReadReport endpoint that allows authenticated administrators to read any file accessible by the root-privileged CyberPanel process. The reportFile parameter in the JSON request body is passed without sanitization directly to Python's open() in cloudManager.py, enabling directory traversal to credential files, SSL and SSH private keys, and JWT secrets. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid CyberPanel administrator credentials - the CVSS 4.0 PR:H metric confirms this is an authenticated-only vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 with vector AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N reflects an accurate picture: network-exploitable with high confidentiality impact, but gated behind administrator authentication (PR:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has acquired CyberPanel administrator credentials - via phishing, credential stuffing against a reused password, or insider access - authenticates to the admin panel and submits a crafted JSON POST to the cloudAPI ReadReport endpoint with a `reportFile` value such as `../../../../root/.ssh/id_rsa`. CyberPanel's root-privileged process opens the file and returns its contents in the response, allowing the attacker to harvest private SSH keys and use them to pivot to any server accessible via those credentials. … |
| Remediation | Upgrade CyberPanel to version 3.0.0 or later, which resolves the unsanitized path handling in the cloudAPI ReadReport endpoint. … Detailed patch versions, workarounds, and compensating controls in full report. |
