DescriptionCVE.org

CyberPanel 2.4.3, fixed in commit eca0c3c, contains an arbitrary file read vulnerability in the file manager component that allows authenticated attackers to read sensitive system files by uploading a crafted ZIP archive containing symbolic links. Attackers can exploit the application's failure to validate symlinks before extraction, causing symbolic links targeting arbitrary filesystem paths outside the user's home directory to persist on disk and be accessed through the web interface.

AnalysisAI

Arbitrary file read in CyberPanel 2.4.3's file manager allows authenticated panel users to escape their home-directory sandbox by uploading a crafted ZIP archive containing symbolic links that target arbitrary filesystem paths. The application extracts ZIP contents without validating whether entries are symlinks, causing those links to persist on disk and remain accessible through the web interface, enabling retrieval of sensitive files such as /etc/shadow or SSH private keys. …

Vulnerability AssessmentAI

Exploitation The attacker must hold a valid CyberPanel user account at any privilege level (PR:L); unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N) correctly reflects a network-reachable, low-complexity flaw requiring only a valid panel account, with no integrity or availability impact - a read-only confidentiality breach. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with a low-privilege CyberPanel hosting account navigates to the file manager, crafts a ZIP archive containing a symlink entry named shadow.txt pointing to /etc/shadow, and uploads it. The panel extracts the archive without symlink validation, planting the link in the attacker's web-accessible directory. …
Remediation The primary fix is to update CyberPanel to the version incorporating commit eca0c3cbeb35af8eaae9fafb094e8ef3cd923643; no specific tagged release version is identified in the available data, so administrators should pull the latest commit from https://github.com/usmannasir/cyberpanel and verify the commit is present. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify all CyberPanel 2.4.3 instances and restrict file-manager access to trusted administrators only; review logs for suspicious ZIP file uploads. …
