CVE-2024-58283 is a remote code execution vulnerability found in WBCE CMS version 1.6.2, specifically within the Elfinder file manager component. The vulnerability stems from CWE-434, which involves the unrestricted upload of files with dangerous types. In this case, authenticated attackers can exploit the file upload functionality of the Elfinder connector to upload malicious PHP files, such as web shells. Once uploaded, these web shells allow attackers to execute arbitrary system commands on the underlying server through a user-controlled parameter, effectively compromising the server's confidentiality, integrity, and availability. The vulnerability does not require user interaction or elevated privileges beyond authentication, making it easier to exploit in environments where attackers have valid credentials. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild yet, the nature of the vulnerability and its ease of exploitation make it a significant threat. The lack of available patches at the time of disclosure increases the urgency for organizations to implement mitigations or consider alternative protective measures.

The exploitation of CVE-2024-58283 can lead to full system compromise of servers running WBCE CMS 1.6.2. Attackers gaining remote code execution can steal sensitive data, modify or delete content, deploy malware, pivot within the network, and disrupt services, causing significant operational and reputational damage. Since the vulnerability requires only authenticated access, insider threats or compromised credentials can be leveraged to exploit this flaw. The high CVSS score reflects the severe impact on confidentiality, integrity, and availability. Organizations relying on WBCE CMS for web content management are at risk of targeted attacks, especially those with weak authentication controls. The absence of known public exploits currently limits widespread exploitation, but the vulnerability's characteristics make it a prime candidate for future attacks once exploit code becomes available. This threat is particularly critical for organizations hosting sensitive or critical web applications on WBCE CMS.

1. Immediately restrict access to the Elfinder file manager to only trusted and necessary users, ideally through network segmentation or VPN access. 2. Implement strong authentication mechanisms, including multi-factor authentication, to reduce the risk of credential compromise. 3. Monitor and audit file upload activities and web server logs for suspicious uploads or execution attempts, focusing on PHP files or unusual parameters. 4. Disable or remove the Elfinder file manager component if not essential to reduce the attack surface. 5. Employ web application firewalls (WAFs) with custom rules to detect and block attempts to upload executable files or access web shells. 6. If possible, apply input validation and file type restrictions on uploads to prevent dangerous file types from being accepted. 7. Keep the WBCE CMS and all components updated; monitor vendor advisories for patches addressing this vulnerability. 8. Consider deploying runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions to detect and block malicious command execution. 9. Conduct regular security assessments and penetration tests focusing on file upload functionalities.
