CVE-2024-40037 identifies a Cross-Site Request Forgery (CSRF) vulnerability in idccms version 1.35, specifically targeting the /admin/userScore_deal.php?mudi=del endpoint. CSRF vulnerabilities allow attackers to induce authenticated users, typically administrators, to execute unwanted actions on a web application without their consent. In this case, the vulnerability permits an attacker to craft malicious requests that, when visited by an authenticated admin, can trigger deletion or modification of user scores or related administrative functions. The vulnerability does not require prior authentication by the attacker but does require the victim to be logged in and interact with a malicious link or webpage. The CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. This means the attacker can remotely exploit the vulnerability over the network with minimal effort, potentially leading to full compromise of the system's data and functionality. No patches or official fixes have been published yet, and no known exploits are reported in the wild, but the vulnerability's nature and impact make it a critical concern for all users of idccms 1.35. The underlying weakness corresponds to CWE-352, which is a well-known web security issue related to missing or ineffective anti-CSRF protections.

The impact of CVE-2024-40037 is significant for organizations using idccms 1.35, especially those relying on the administrative functionalities exposed by the vulnerable endpoint. Successful exploitation can lead to unauthorized deletion or modification of user scores or other administrative data, potentially disrupting business operations, corrupting data integrity, and exposing sensitive information. The high CVSS score reflects the potential for complete compromise of confidentiality, integrity, and availability. This can result in loss of trust, financial damage, and operational downtime. Since the vulnerability can be exploited remotely without authentication, attackers can target organizations globally, including government, education, and commercial sectors that use idccms. The requirement for user interaction (an authenticated admin clicking a malicious link) means social engineering or phishing campaigns could be leveraged to exploit this vulnerability. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for mitigation, as attackers may develop exploits rapidly once the vulnerability is public.

To mitigate CVE-2024-40037 effectively, organizations should implement multiple layers of defense beyond waiting for an official patch. First, apply strict anti-CSRF tokens on all state-changing administrative endpoints, ensuring that requests without valid tokens are rejected. Second, enforce referer header validation to confirm that requests originate from trusted sources within the application. Third, restrict administrative access by IP whitelisting or VPN-only access to reduce exposure to external attackers. Fourth, implement multi-factor authentication (MFA) for admin accounts to reduce the risk of session hijacking or credential theft. Fifth, educate administrators about phishing and social engineering risks to minimize the chance of clicking malicious links. Sixth, monitor web server logs and application behavior for unusual or unauthorized requests targeting the vulnerable endpoint. Finally, maintain regular backups of critical data to enable recovery in case of compromise. Organizations should also stay alert for official patches or updates from idccms developers and apply them promptly once available.
