Deeper analysis

WBCE CMS version 1.6.2 is affected by CVE-2024-58283, a remote code execution vulnerability in the Elfinder file manager component. The issue stems from the elfinder connector's file upload functionality, which permits authenticated attackers to upload malicious PHP files, such as web shells, and execute arbitrary system commands via a user-controlled parameter. This flaw is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) and carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H).

Authenticated attackers with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N). Successful exploitation allows uploading a malicious PHP web shell through the Elfinder interface, followed by remote execution of arbitrary system commands on the server, resulting in high confidentiality, integrity, and availability impacts (C:H/I:H/A:H).

Advisories, including those from VulnCheck on the remote code execution via Elfinder file upload and a public proof-of-concept exploit on Exploit-DB (ID 52039), document the issue. The WBCE CMS official site and GitHub repository for version 1.6.2 provide access to the affected source code.
