CVE-2025-11272 is an improper authorization vulnerability identified in SeriaWei's ZKEACMS content management system, specifically in versions 4.0 through 4.3. The vulnerability resides in the Delete function of the UrlRedirectionController.cs file, which handles POST requests for URL redirection management. Due to insufficient authorization controls, an attacker with limited privileges can remotely invoke this function to delete URL redirections without proper permission validation. This flaw allows unauthorized modification of URL redirection data, potentially disrupting website navigation, breaking links, or redirecting users to unintended destinations. The vulnerability is exploitable remotely over the network without requiring user interaction or elevated privileges beyond limited access, making it relatively easy to exploit. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no authentication required, and partial impacts on integrity and availability. The vendor was notified early but has not issued a patch or response, and no official fixes or mitigations have been published. Although no known exploits are currently active in the wild, the public disclosure of exploit details increases the risk of exploitation. Organizations using ZKEACMS should assume potential threat and take proactive measures to secure the affected component.

For European organizations, the improper authorization vulnerability in ZKEACMS could lead to unauthorized deletion of URL redirections, impacting website integrity and availability. This could disrupt user access to critical web resources, degrade customer experience, and potentially cause loss of business or reputational damage. Organizations relying on ZKEACMS for public-facing websites or internal portals may face service interruptions or manipulation of navigation flows. Attackers could exploit this vulnerability to remove or alter redirections, potentially facilitating phishing or redirecting users to malicious sites if combined with other vulnerabilities. The impact is particularly significant for sectors with high web presence such as e-commerce, government, and media organizations. Given the lack of vendor response and patch, European entities must consider this vulnerability a persistent risk until mitigated. The medium severity score indicates moderate risk but with potential for escalation if combined with other weaknesses.

To mitigate CVE-2025-11272, European organizations should immediately restrict access to the UrlRedirectionController's Delete function by implementing network-level controls such as IP whitelisting or firewall rules limiting POST requests to trusted administrators only. Review and enhance authorization logic in the application code to enforce strict permission checks before allowing deletion of URL redirections. If possible, disable or remove the affected functionality temporarily until a vendor patch is available. Implement detailed logging and monitoring of POST requests targeting URL redirection endpoints to detect and respond to suspicious activity promptly. Conduct thorough audits of user privileges to ensure no unnecessary access is granted to low-privilege accounts. Consider deploying web application firewalls (WAFs) with custom rules to block unauthorized deletion attempts. Engage with the vendor or community for updates or unofficial patches and plan for timely application of fixes once released. Additionally, educate administrators about this vulnerability and the importance of cautious privilege assignment.
