CVE-2024-39156 identifies a Cross-Site Request Forgery (CSRF) vulnerability in idccms version 1.35, specifically within the administrative component located at /admin/keyWord_deal.php?mudi=add. CSRF vulnerabilities occur when an attacker tricks an authenticated user, typically an administrator, into submitting unauthorized requests to a web application without their consent. In this case, the vulnerability allows an attacker to perform actions that modify keywords or related administrative data by exploiting the lack of proper CSRF protections such as anti-CSRF tokens or same-site request validation. The CVSS 3.1 base score of 3.8 reflects a low severity, primarily because exploitation requires the attacker to have high privileges (authenticated administrator) and no user interaction is needed. The vulnerability impacts confidentiality and integrity to a limited extent, as unauthorized changes to administrative data could occur, but it does not affect system availability. No known public exploits or patches are currently available, indicating that the vulnerability is newly disclosed and not yet actively exploited. The vulnerability is categorized under CWE-352, which is the standard classification for CSRF issues. Given the administrative context, successful exploitation could allow attackers to manipulate backend configurations or data, potentially leading to further security risks if combined with other vulnerabilities or misconfigurations.

The primary impact of CVE-2024-39156 is the unauthorized modification of administrative data within idccms, which could compromise the integrity and confidentiality of the system's keyword management functions. Although the vulnerability does not directly affect availability, unauthorized changes could lead to misconfigurations or data inconsistencies that degrade system reliability or user trust. Since exploitation requires high privileges (an authenticated administrator), the risk is somewhat mitigated by access controls; however, if an attacker gains administrative credentials or uses social engineering to trick an admin, they could leverage this vulnerability to perform unauthorized actions. This could facilitate further attacks, such as privilege escalation or data leakage, especially in environments where idccms is used to manage critical content or services. Organizations relying on idccms 1.35 should consider the potential for indirect impacts on their operational security and data integrity. The absence of known exploits reduces immediate risk, but the vulnerability should be addressed promptly to prevent future exploitation.

To mitigate CVE-2024-39156, organizations should implement robust CSRF protections within the idccms administrative interface. This includes adding anti-CSRF tokens to all state-changing requests, especially those in /admin/keyWord_deal.php?mudi=add, to ensure that requests originate from legitimate sources. Additionally, enforcing same-site cookie attributes and validating the HTTP Referer header can provide supplementary defenses. Restrict administrative access to trusted IP addresses or VPNs to reduce exposure. Regularly audit and monitor administrative actions for unusual activity that could indicate exploitation attempts. Since no official patch is currently available, consider applying custom patches or workarounds that disable or secure the vulnerable endpoint until an official fix is released. Educate administrators about phishing and social engineering risks to prevent credential compromise. Finally, maintain up-to-date backups and incident response plans to recover quickly if exploitation occurs.
