CVE-2024-39157 identifies a Cross-Site Request Forgery (CSRF) vulnerability in idccms version 1.35, specifically within the administrative endpoint /admin/ipRecord_deal.php?mudi=del&dataType=&dataID=1. CSRF vulnerabilities allow attackers to induce authenticated users to perform unwanted actions on a web application without their consent by exploiting the user's active session. In this case, the vulnerability affects a high-privilege administrative function that handles deletion operations on IP records. The CVSS 3.1 base score of 3.8 reflects a low severity rating, primarily because exploitation requires the attacker to have the victim already authenticated with high privileges (PR:H), and no user interaction beyond visiting a malicious link is needed (UI:N). The attack vector is network-based (AV:N), and the scope is unchanged (S:U). The impact on confidentiality and integrity is limited (C:L, I:L), with no impact on availability (A:N). No patches or known exploits are currently available or reported, indicating this vulnerability is newly disclosed. The underlying weakness corresponds to CWE-352, which is a common web application security issue where anti-CSRF tokens or other protections are missing or insufficient. This vulnerability could allow attackers to manipulate administrative functions such as deleting IP records, potentially disrupting administrative workflows or causing data inconsistencies.

The primary impact of CVE-2024-39157 is the unauthorized execution of administrative actions by an attacker leveraging an authenticated administrator's session. Although the vulnerability does not allow direct remote code execution or full system compromise, it can lead to unauthorized deletion of IP records, which may affect audit trails, security monitoring, or network management. The limited confidentiality and integrity impact means sensitive data exposure or modification is minimal but still present. Since availability is unaffected, the system remains operational. Organizations relying on idccms for content management or administrative tasks could face operational disruptions or data integrity issues if this vulnerability is exploited. The requirement for high privilege authentication limits the attack surface to administrators or trusted users, reducing the risk of widespread exploitation. However, in environments where administrative credentials are shared or weakly protected, the risk increases. The absence of known exploits in the wild suggests limited immediate threat but highlights the need for proactive mitigation to prevent future attacks.

To mitigate CVE-2024-39157, organizations should implement robust anti-CSRF protections such as synchronizer tokens or double-submit cookies on all state-changing administrative endpoints, especially /admin/ipRecord_deal.php. Applying strict referer or origin header validation can provide additional defense layers. Limiting administrative access to trusted networks or VPNs reduces exposure. Enforcing multi-factor authentication (MFA) for administrative accounts can mitigate risks from compromised credentials. Regularly auditing and monitoring administrative actions and logs can help detect suspicious activities. If an official patch becomes available, it should be applied promptly. In the absence of patches, consider temporarily disabling or restricting access to vulnerable endpoints. Educating administrators about the risks of CSRF and encouraging safe browsing practices can reduce the likelihood of exploitation. Finally, employing web application firewalls (WAFs) with CSRF detection rules may provide an additional security layer.
