CVE-2024-33442 identifies a vulnerability in flusity-CMS version 2.33, specifically within the add_post.php component. This vulnerability allows a remote attacker to execute arbitrary code on the target system. The root cause is linked to CWE-94, which involves improper control over dynamically generated code, such as unsanitized input being passed to an eval() function or similar code execution mechanisms. The attack vector is network-based (AV:N), requiring low attack complexity (AC:L) but does require privileges (PR:L), indicating that the attacker must have some level of authenticated access to the CMS. No user interaction is needed (UI:N), and the scope remains unchanged (S:U). The vulnerability impacts the integrity of the system (I:L) but does not affect confidentiality or availability. Despite the lack of known exploits in the wild and absence of official patches, the vulnerability presents a risk of code injection that could allow attackers to manipulate CMS content or execute malicious payloads. The lack of specified affected versions beyond 2.33 suggests that this version is confirmed vulnerable, but further version analysis is needed. The vulnerability was reserved in April 2024 and published in May 2024, indicating recent discovery.

The primary impact of CVE-2024-33442 is on the integrity of systems running flusity-CMS version 2.33. Successful exploitation could allow attackers to execute arbitrary code, potentially enabling unauthorized content manipulation, deployment of malicious scripts, or further lateral movement within the network. While confidentiality and availability are not directly impacted, the integrity compromise could lead to reputational damage, data tampering, and indirect availability issues if malicious code disrupts normal operations. Organizations relying on flusity-CMS for content management, especially those with sensitive or high-traffic websites, could face defacement, misinformation dissemination, or use as a pivot point for broader attacks. The requirement for some level of privileges reduces the risk somewhat but does not eliminate it, especially in environments with weak access controls or credential management.

1. Restrict access to the add_post.php component by enforcing strict authentication and authorization controls, ensuring only trusted users can interact with this functionality. 2. Implement input validation and sanitization on all user-supplied data to prevent code injection, particularly focusing on parameters handled by add_post.php. 3. Monitor CMS logs for unusual activity or unexpected code execution attempts related to the add_post.php endpoint. 4. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting code injection vectors. 5. Conduct regular security audits and code reviews of the CMS, especially custom or third-party components, to identify and remediate unsafe coding practices. 6. Isolate the CMS environment and limit its network privileges to reduce potential lateral movement if exploited. 7. Stay alert for official patches or updates from the flusity-CMS maintainers and apply them promptly once available. 8. Educate administrators and developers about the risks of CWE-94 vulnerabilities and secure coding standards to prevent similar issues.
