Technical Analysis
ContiNew Admin's multipart upload endpoints do not enforce file-upload permission checks or validate file types against an allowlist. Authenticated users can initiate chunked uploads, send file parts, and complete uploads, resulting in arbitrary files being stored in the backend storage. These files can be accessed through web server URLs, potentially leading to unauthorized file storage and exposure.
Potential Impact
Authenticated users can upload files with arbitrary extensions to the backend storage, which are accessible via web URLs. This could lead to unauthorized file storage and potential exposure of malicious files, increasing the risk of further attacks or data compromise. The vulnerability has a CVSS 4.0 score of 7.1, indicating high severity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user permissions and monitor upload endpoints for suspicious activity.
