CVE-2024-40035 identifies a Cross-Site Request Forgery (CSRF) vulnerability in idccms version 1.35, specifically targeting the administrative endpoint /admin/userLevel_deal.php?mudi=add. CSRF vulnerabilities occur when an attacker tricks an authenticated user, typically an administrator, into submitting a forged HTTP request that performs unintended actions on a web application. In this case, the vulnerability allows unauthorized modification of user levels, which could lead to privilege escalation or unauthorized access changes. The CVSS 3.1 vector indicates the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), no user interaction (UI:N), and affects confidentiality, integrity, and availability to a limited degree (C:L/I:L/A:L). The vulnerability is classified under CWE-352, which covers CSRF issues. No patches or exploits are currently documented, but the lack of CSRF protections in the administrative interface exposes the system to potential misuse if an attacker can lure an admin to a malicious site or execute crafted requests. This vulnerability highlights the importance of implementing anti-CSRF tokens, validating HTTP headers such as Origin and Referer, and enforcing strict access controls on sensitive endpoints.

The primary impact of CVE-2024-40035 is the potential unauthorized modification of user privileges within the idccms administrative interface. Successful exploitation could allow attackers to escalate privileges, create or modify user accounts, or disrupt normal administrative operations, affecting the confidentiality, integrity, and availability of the CMS-managed content and user data. While the attack vector requires local access, the absence of user interaction means that an attacker could exploit this vulnerability through automated or crafted requests if they can induce an authenticated administrator to visit a malicious page or execute a malicious request. This could lead to unauthorized administrative control, data manipulation, or service disruption. Organizations relying on idccms for content management may face risks of data breaches, defacement, or operational downtime. The medium severity score reflects the moderate risk, given the requirement for local access and no known widespread exploitation, but the potential for privilege escalation and administrative compromise remains significant.

To mitigate CVE-2024-40035, organizations should implement robust anti-CSRF protections on all administrative endpoints, especially /admin/userLevel_deal.php?mudi=add. This includes generating and validating unique CSRF tokens for each user session and sensitive request to ensure that requests originate from legitimate sources. Additionally, validating the Origin and Referer HTTP headers can help detect and block unauthorized cross-site requests. Access to administrative interfaces should be restricted through network segmentation, IP whitelisting, or VPN requirements to limit exposure. Employing multi-factor authentication (MFA) for administrative accounts further reduces risk. Regularly auditing and monitoring administrative actions can help detect suspicious activities. Since no official patches are currently available, organizations should consider applying custom patches or workarounds to enforce CSRF protections or temporarily disable vulnerable functionalities if feasible. Keeping the CMS and all dependencies updated and following secure coding practices for web applications is essential to prevent similar vulnerabilities.
