CyberPanel versions 2.4.3 through 2.4.5 expose unauthenticated AI Scanner debugging endpoints that disclose administrator usernames, API-key prefixes, scan identifiers, target domains, and account metadata. Unauthenticated attackers can enumerate panel administrators and recent scanner activity to inventory multi-tenant installations and facilitate follow-on attacks.

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.

CyberPanel 2.4.3, fixed in commit eca0c3c, contains an authenticated remote code execution vulnerability in the remote backup feature that allows authenticated attackers to gain root-level SSH access by supplying a malicious remote server address. Attackers can exploit the unverified SSH public key retrieval process to write an attacker-controlled public key directly to /root/.ssh/authorizedkeys, granting persistent root access to the host system.

CyberPanel 2.4.3, fixed in commit eca0c3c, contains an authenticated command injection vulnerability in the remote backup transfer feature that allows authenticated attackers to execute arbitrary OS commands by controlling a remote server's API response. Attackers can inject malicious commands through a crafted directory name in the remote server's API response, which bypasses security middleware validation and is passed unsanitized to the OS command execution function.

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.

CyberPanel versions prior to 2.4.5 contain an authentication bypass vulnerability in the AI Scanner worker API endpoints that allows unauthenticated remote attackers to write arbitrary data to the database by sending requests to the /api/ai-scanner/status-webhook and /api/ai-scanner/callback endpoints. Attackers can exploit the lack of authentication checks to cause denial of service through storage exhaustion, corrupt scan history records, and pollute database fields with malicious data.

CyberPanel versions prior to 2.4.5 contain a stored cross-site scripting vulnerability in the AI Scanner dashboard where the POST /api/ai-scanner/callback endpoint lacks authentication and allows unauthenticated attackers to inject malicious JavaScript by overwriting the findingsjson field of ScanHistory records. Attackers can inject JavaScript that executes in an administrator's authenticated session when they visit the AI Scanner dashboard, allowing them to issue same-origin requests to plant cron jobs and achieve remote code execution on the server.

CyberPanel contains an incorrect default permissions vulnerability that allows for authentication bypass and the execution of arbitrary commands using shell metacharacters in the statusfile property.

CyberPanel contains an incorrect default permissions vulnerability that allows a remote, unauthenticated attacker to execute commands as root.

CyberPanel through 1.9.1, fixed in commit b198460, contains a missing authorization vulnerability in the cancelBackupCreation handler that allows authenticated users to kill, delete, and corrupt other tenants' backups. Attackers can send crafted POST requests with arbitrary backupCancellationDomain and fileName parameters to terminate backup processes, delete backup archives, corrupt backup status files, and remove database records belonging to other tenants.

CyberPanel 2.1 contains a command execution vulnerability that allows authenticated attackers to read arbitrary files and execute remote code by exploiting symlink attacks through the filemanager controller endpoint. Attackers can manipulate the completeStartingPath parameter in POST requests to /filemanager/controller to create symbolic links, read sensitive files like database credentials, and execute arbitrary shell commands through the /websites/fetchFolderDetails endpoint.

CyberPanel (aka Cyber Panel) before 6778ad1 does not require the FilemanagerAdmin capability for restartMySQL actions.

CyberPanel before 2.3.8 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the phpSelection field to the websites/submitWebsiteCreation URI.

CyberPanel (aka Cyber Panel) before f0cf648 allows XSS via token or username to plogical/phpmyadminsignin.php.

CyberPanel (aka Cyber Panel) before 2.3.5 allows Command Injection via completePath in the ProcessUtilities.outputExecutioner() sink. There is /filemanager/upload (aka File Manager upload) unauthenticated remote code execution via shell metacharacters.

An issue was discovered in CyberPanel through 1.8.4. On the user edit page, an attacker can edit the administrator's e-mail and password because of the lack of CSRF protection.
