CVE-2024-39155 identifies a Cross-Site Request Forgery (CSRF) vulnerability in idccms version 1.35, affecting the administrative endpoint /admin/ipRecord_deal.php?mudi=add. CSRF vulnerabilities occur when a web application does not properly verify that requests made to sensitive endpoints originate from legitimate users, allowing attackers to craft malicious web pages or links that cause authenticated users to unknowingly perform actions on the vulnerable system. In this case, the vulnerability requires the attacker to have some level of privileges (PR:L) and the victim to interact with a malicious request (UI:R). The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), user interaction required (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), low integrity impact (I:L), and low availability impact (A:L). This means an attacker can remotely exploit the vulnerability over the network, with low complexity, but must rely on a user with some privileges to interact with the malicious request. The primary risk is unauthorized disclosure or access to sensitive information (high confidentiality impact), with limited potential for data modification or service disruption. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly.

The primary impact of this CSRF vulnerability is unauthorized actions performed on behalf of authenticated users with some privileges, potentially leading to unauthorized disclosure of sensitive information due to the high confidentiality impact rating. Although integrity and availability impacts are low, attackers could leverage this vulnerability to manipulate administrative functions or gather sensitive data without authorization. Organizations running idccms 1.35, especially those with exposed administrative interfaces, face risks of data breaches and unauthorized configuration changes. The requirement for user interaction and privileges limits the ease of exploitation but does not eliminate the risk, particularly in environments where users have elevated privileges and may be targeted via phishing or malicious websites. The lack of known exploits reduces immediate threat but does not preclude future exploitation. Overall, this vulnerability could undermine trust in the affected system and lead to compliance and reputational damage if exploited.

To mitigate CVE-2024-39155, organizations should implement strict anti-CSRF protections on the affected endpoint, such as synchronizer tokens (CSRF tokens) that validate the origin of requests. Web application firewalls (WAFs) can be configured to detect and block suspicious CSRF attempts targeting the /admin/ipRecord_deal.php?mudi=add endpoint. Restricting administrative access to trusted networks or VPNs reduces exposure. Additionally, enforcing least privilege principles to minimize user privileges reduces the impact of potential exploitation. Monitoring and logging administrative actions can help detect anomalous behavior indicative of CSRF exploitation. Since no official patch is currently available, organizations should consider applying custom patches or temporary workarounds, such as disabling the vulnerable functionality if feasible. User education to avoid interacting with untrusted links while authenticated can also reduce risk. Finally, stay updated with vendor advisories for any forthcoming patches.
