Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly remediates the specific flaw in the Elfinder connector that allows unrestricted upload of malicious PHP web shells leading to RCE.

SI-10 Information Input Validation good match

prevent

Validates file upload inputs to block dangerous PHP files and prevent exploitation of the unrestricted upload vulnerability.

SI-3 Malicious Code Protection good match

preventdetect

Scans uploads and system entry points for malicious code like PHP web shells to prevent and detect RCE attempts.

NVD Description

WBCE CMS version 1.6.2 contains a remote code execution vulnerability that allows authenticated attackers to upload malicious PHP files through the Elfinder file manager. Attackers can exploit the file upload functionality in the elfinder connector to upload a web shell…

and execute arbitrary system commands through a user-controlled parameter.

Deeper analysisAI

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.
