Published: 10 March 2022
Summary
CVE-2022-24651 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Sentcms Sentcms. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 13.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
sentcms 4.0.x is affected by an unrestricted file upload flaw (CWE-434) that exposes an unauthorized upload interface at the path /user/upload/upload. Remote attackers can supply arbitrary files, including PHP scripts, that the application stores and executes without restriction, leading to remote code execution on the server. The vulnerability received a CVSS 3.1 base score of 9.8 reflecting network attack vector, low complexity, and no required privileges or user interaction.
Because authentication is not enforced, any unauthenticated network attacker can upload and execute malicious code, resulting in complete compromise of confidentiality, integrity, and availability on the affected installation.
The associated EPSS probability rose from low values to a peak of 0.1567 on 2025-01-22 before receding to the current 0.0265, indicating that exploitation interest appeared after public disclosure.

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.
