Deeper analysis
sentcms 4.0.x contains an unrestricted file upload vulnerability tracked as CVE-2022-24652 and CWE-434. The flaw resides in an unauthorized upload interface that permits remote attackers to place arbitrary PHP files, resulting in code execution under the path /admin/upload/upload. The issue received a CVSS 3.1 score of 9.8 reflecting network-accessible exploitation with no required credentials or user interaction.
Unauthenticated attackers can send crafted requests to the upload endpoint and write malicious PHP payloads directly to the web root. Successful exploitation grants full control over the application, including the ability to execute arbitrary server-side code, read or modify data, and pivot within the hosting environment.
EPSS for the CVE remained low after the March 2022 disclosure but rose materially to a peak of 0.1567 on 2025-01-22 before receding to the current value of 0.0265, indicating a later surge in exploitation interest that warrants renewed attention. The two referenced URLs point to the same technical write-up detailing the upload flaw but contain no vendor patch or mitigation guidance.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
