Lifecycle Timeline
7DescriptionCVE.org
CyberPanel versions prior to 2.4.4 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 findings_json 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.
AnalysisAI
Stored cross-site scripting in CyberPanel's AI Scanner dashboard chains to unauthenticated remote code execution on versions prior to 2.4.4, exploitable by any network-reachable attacker without credentials. The POST /api/ai-scanner/callback endpoint lacks authentication, permitting arbitrary JavaScript injection into the findings_json field of ScanHistory records; when an administrator visits the AI Scanner dashboard, the script executes in their privileged browser session and issues same-origin API calls to plant OS-level cron jobs. A public proof-of-concept exploit is confirmed; no CISA KEV active exploitation listing is present at time of analysis, though the low skill requirement due to POC availability elevates real-world risk significantly.
Technical ContextAI
CyberPanel (CPE: cpe:2.3:a:usmannasir:cyberpanel:*:*:*:*:*:*:*:*) is a Python/Django-based web hosting control panel used by VPS and shared-hosting providers. The root cause is CWE-79 (Improper Neutralization of Input During Web Page Generation - Stored XSS): the AI Scanner callback endpoint accepts and persists attacker-controlled JSON without input sanitization or output encoding, and without enforcing any authentication check. Stored payloads survive in the ScanHistory database table until an administrator renders the AI Scanner dashboard, at which point the browser executes the injected JavaScript within the admin's authenticated origin context. The attack then pivots through CyberPanel's own cron management API - accessible same-origin - to write attacker-supplied commands to the system crontab, bridging a web-layer flaw into OS-level execution. The patch commit 0a099b1b193946555fbdd387a28486b1521f9961 modifies plogical/acl.py to return an access-denied response (return 0) for unauthenticated callers on the callback endpoint, enforcing the missing authentication gate.
RemediationAI
Upgrade CyberPanel to version 2.4.4 or later, which incorporates the upstream fix at https://github.com/usmannasir/cyberpanel/commit/0a099b1b193946555fbdd387a28486b1521f9961; note that version 2.4.4 is sourced from EUVD data and has not been independently verified against a tagged GitHub release - confirm via the official CyberPanel release channel. If immediate patching is not possible, block external and untrusted-network access to the /api/ai-scanner/callback endpoint via reverse proxy or firewall ACL; this prevents new payload injection but does not neutralize payloads already stored in ScanHistory records. To address stored payloads pending patching, purge the ScanHistory table via the CyberPanel database - trade-off is loss of historical scan data. Additionally, restrict CyberPanel admin dashboard access to known-trusted IP ranges, reducing the surface for XSS delivery to administrator browsers. Do not rely on Content Security Policy alone as a compensating control, as CyberPanel's CSP configuration would need independent verification.
