CVE-2024-58281
Published: 10 December 2025
Summary
CVE-2024-58281 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Dotclear Dotclear. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 45.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2024-58281 is a remote code execution vulnerability affecting Dotclear version 2.29, a PHP-based blogging platform. The flaw resides in the media upload functionality, which permits authenticated attackers to upload malicious PHP files. By crafting a PHP shell containing a command execution form, attackers can exploit this unrestricted file upload process to achieve arbitrary code execution on the server.
The vulnerability requires low privileges, as indicated by its CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Any authenticated user, such as a low-level contributor or editor, can exploit it over the network with low complexity and no user interaction. Successful exploitation grants high-impact confidentiality, integrity, and availability compromises, enabling full system access through the uploaded and executed PHP shell (CWE-434: Unrestricted Upload of File with Dangerous Type).
Advisories from Vulncheck document the remote code execution via authenticated file upload, while Exploit-DB hosts a public exploit (ID 52037). Dotclear repositories on Git and GitHub provide access to source code, potentially including patches in the master branch.
An exploit is publicly available, indicating potential for real-world abuse against unpatched Dotclear 2.29 installations.
