CVE-2024-39023 identifies a Cross-Site Request Forgery (CSRF) vulnerability in idccms version 1.35, a content management system. The vulnerability exists in the admin/info_deal.php script, specifically when accessed with the parameters mudi=add&nohrefStr=close. CSRF vulnerabilities allow attackers to induce authenticated users, typically administrators, to perform unwanted actions without their consent by exploiting the trust a web application places in the user's browser. In this case, an attacker can craft a malicious request that, when executed by an authenticated admin, can add or modify administrative data or settings. The CVSS 3.1 base score of 8.8 indicates a high-severity issue, with the vector string AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H meaning the attack is network exploitable, requires low attack complexity, no privileges, but does require user interaction (the admin must be tricked into clicking or loading a malicious link). The impact on confidentiality, integrity, and availability is high, as successful exploitation could allow attackers to manipulate administrative functions, potentially leading to data breaches, unauthorized changes, or service disruption. No patches or known exploits are currently documented, highlighting the need for proactive mitigation. The vulnerability is classified under CWE-352, which is the standard identifier for CSRF issues.

The potential impact of CVE-2024-39023 is significant for organizations using idccms 1.35. Successful exploitation could lead to unauthorized administrative actions, resulting in data theft, unauthorized configuration changes, or service outages. Because the vulnerability affects administrative functions, attackers could compromise the entire CMS, leading to website defacement, insertion of malicious content, or pivoting to internal networks. This can damage organizational reputation, cause regulatory compliance violations, and result in financial losses. The requirement for user interaction (an admin clicking a malicious link) somewhat limits the attack vector but does not eliminate risk, especially in environments where phishing or social engineering is common. The lack of known exploits in the wild suggests this vulnerability is newly disclosed, so organizations have a window to respond before widespread exploitation occurs.

To mitigate CVE-2024-39023, organizations should first check for any official patches or updates from the idccms vendor and apply them promptly once available. In the absence of patches, implement strict anti-CSRF tokens in all administrative forms and verify the origin of requests on the server side. Administrators should be trained to recognize phishing attempts and avoid clicking on suspicious links. Employ Content Security Policy (CSP) headers to reduce the risk of malicious script execution. Restrict administrative access by IP whitelisting or VPN-only access to reduce exposure. Additionally, enable multi-factor authentication (MFA) for admin accounts to limit the impact of compromised credentials. Regularly audit logs for unusual administrative actions and consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block CSRF attack patterns targeting the vulnerable endpoint.
