CyberPanel versions prior to 2.4.4 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 may leverage the lack of authentication checks to cause denial of service through storage exhaustion, corrupt scan history records, and pollute database fields with malicious data. The CVSS score for this vulnerability is 8.8, categorizing it as high severity.
Risk to organizations includes potential data corruption and denial of service, which can severely disrupt normal operations. Given its high severity rating, organizations should prioritize patching immediately.
As of now, there is no public exploit confirmed, and this vulnerability has not been added to the Known Exploited Vulnerabilities (KEV) catalog, indicating that active exploitation is currently unknown. However, the potential impacts of this vulnerability necessitate immediate attention.
Organizations are advised to review their deployment of CyberPanel and ensure they upgrade to version 2.4.4 or later to mitigate this vulnerability.
Vulnerability Details
The authentication bypass vulnerability in CyberPanel arises from the AI Scanner worker API endpoints, specifically the /api/ai-scanner/status-webhook and /api/ai-scanner/callback endpoints. This absence of authentication checks enables unauthorized access to sensitive database operations. The CWE classification for this vulnerability is CWE-306, which denotes an authentication bypass.
The CVSS 4.0 score of 8.8 indicates a high severity level, with an attack vector of NETWORK and low attack complexity. The lack of necessary privileges or user interaction required further underscores the risk associated with this vulnerability.
Technical Analysis
The root cause of this vulnerability lies in the insufficient access controls implemented on the API endpoints. Attackers may exploit this vulnerability remotely without any authentication, leading to potential data manipulation or denial of service through storage exhaustion.
The attack vector is network-based, allowing attackers to send crafted requests to the vulnerable endpoints. The attack complexity is low, as no specialized knowledge or techniques are required to exploit this vulnerability. No user interaction is necessary for the exploitation to succeed.
Risk & Impact Analysis
The impact on organizations deploying CyberPanel can be significant. The ability for unauthenticated attackers to write arbitrary data to the database may lead to data integrity issues, affecting the reliability of scan history records and other critical data. Furthermore, denial of service attacks can severely disrupt service availability, leading to potential revenue loss and damage to reputation.
Organizations should assess the potential blast radius of this vulnerability in their environment. Given the CVSS score, it is advisable to address this vulnerability with high urgency, ensuring that all instances of CyberPanel are updated to mitigate risks.
