CVE-2024-44724 is a PHP code injection vulnerability affecting AutoCMS version 5.4, discovered in the /admin/site_add.php endpoint via the txtsite_url parameter. This vulnerability falls under CWE-94 (Improper Control of Generation of Code), allowing attackers to inject crafted PHP code that the server executes. The attack vector is network-based (AV:N), with low attack complexity (AC:L), but requires high privileges (PR:H), specifically administrative access to the CMS backend. No user interaction is needed (UI:N), and the vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this flaw enables an attacker to execute arbitrary PHP code, potentially leading to full system compromise, data theft, defacement, or service disruption. The vulnerability was reserved on August 21, 2024, and published on September 9, 2024. No patches or known exploits are currently reported, but the lack of a patch means systems remain vulnerable. The vulnerability’s presence in a CMS platform used for website management makes it a critical concern for organizations relying on AutoCMS for their web presence.

The impact of CVE-2024-44724 is significant for organizations using AutoCMS 5.4. Successful exploitation allows attackers to execute arbitrary PHP code with administrative privileges, potentially leading to full system takeover. This can result in unauthorized data access or theft, website defacement, insertion of malicious content, disruption of services, and use of compromised servers as pivot points for further attacks. The confidentiality, integrity, and availability of affected systems are all at high risk. Organizations hosting sensitive or critical web applications on AutoCMS are particularly vulnerable. The lack of a patch increases exposure time, and attackers who gain admin credentials or exploit other vulnerabilities to escalate privileges could leverage this flaw to devastating effect. This threat could also damage organizational reputation and lead to regulatory compliance issues if sensitive data is compromised.

To mitigate CVE-2024-44724, organizations should immediately restrict access to the AutoCMS administrative interface to trusted IP addresses and enforce strong authentication mechanisms, including multi-factor authentication. Regularly audit and monitor admin account activities for suspicious behavior. Employ web application firewalls (WAFs) with custom rules to detect and block attempts to inject PHP code via the txtsite_url parameter. Disable or limit PHP code execution in directories where it is not necessary. Maintain strict input validation and sanitization practices, especially for parameters that interact with code execution. Organizations should track vendor communications closely and apply official patches as soon as they become available. Additionally, consider isolating the CMS environment to minimize lateral movement if compromise occurs. Conduct regular backups and test restoration procedures to ensure resilience against potential exploitation.
