The vulnerability identified as CVE-2019-16677 represents a cross-site request forgery flaw within the idreamsoft iCMS version 7.0 content management system. This security weakness specifically manifests in the administrative control panel through the admincp.php script with parameters app=members and do=del, which governs member deletion functionality. The issue arises from the absence of proper anti-CSRF mechanisms within the affected administrative interface, creating a significant security risk for systems utilizing this CMS version.
The technical nature of this vulnerability stems from the lack of anti-CSRF tokens or similar validation mechanisms in the member deletion process. When an authenticated administrator visits a malicious website or clicks on a crafted link, the attacker can potentially trigger the deletion of user accounts without the administrator's knowledge or explicit consent. This occurs because the administrative actions are performed using the current session context, bypassing normal authorization checks that should validate the legitimacy of the request origin. The vulnerability falls under CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in software applications.
The operational impact of this vulnerability extends beyond simple account deletion, as it can enable attackers to compromise the integrity of user data within the CMS system. An attacker who successfully exploits this CSRF flaw could systematically remove user accounts, potentially leading to data loss, disruption of services, and undermining user trust in the platform. The administrative context of the vulnerability means that the attacker gains elevated privileges within the system, potentially allowing for further exploitation or data manipulation. This type of attack is particularly dangerous because it can be executed without requiring authentication credentials from the administrator, making it difficult to detect and prevent through traditional authentication measures.
Organizations using idreamsoft iCMS v7.0 should implement immediate mitigations including the deployment of anti-CSRF tokens for all administrative actions, particularly those involving data modification or deletion. The system should enforce proper request validation by requiring unique tokens that are tied to the user session and validated before processing any administrative requests. Additionally, implementing proper referer header validation and using the SameSite cookie attributes can provide additional layers of protection against this type of attack. Organizations should also consider implementing web application firewalls that can detect and block suspicious CSRF patterns. This vulnerability aligns with ATT&CK technique T1213.002 which covers data from information repositories, and demonstrates the importance of proper session management and request validation in preventing unauthorized administrative actions. The remediation should include updating to the latest version of the CMS where such vulnerabilities have been addressed through proper CSRF token implementation and enhanced administrative security controls.
