CVE-2025-11272 is a medium-severity vulnerability affecting SeriaWei's ZKEACMS content management system versions 4.0 through 4.3. The flaw resides in the Delete function within the UrlRedirectionController.cs file, specifically in the POST request handler component. The vulnerability is due to improper authorization checks, allowing an attacker to remotely invoke the Delete function without sufficient privileges. This means an attacker with network access can potentially delete URL redirections or related resources managed by the CMS without proper authentication or authorization. The vulnerability does not require user interaction and can be exploited remotely with low attack complexity, though it requires some level of privileges (PR:L) indicating that the attacker must have limited privileges or be authenticated with a low-level account. The impact on confidentiality is none, but integrity and availability are impacted to a limited extent, as unauthorized deletion could disrupt URL redirection functionality, potentially causing denial of service or misdirection of users. The vendor was contacted but did not respond, and no patches or mitigations have been publicly released yet. While no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation.

For European organizations using ZKEACMS versions 4.0 to 4.3, this vulnerability poses a risk primarily to the integrity and availability of web services relying on URL redirection managed by the CMS. Attackers exploiting this flaw could delete critical URL redirections, leading to broken links, service disruptions, or potential redirection to malicious sites if combined with other vulnerabilities. This could affect customer trust, cause operational downtime, and potentially impact business continuity. Organizations in sectors with high reliance on web presence, such as e-commerce, government portals, and media, may experience reputational damage and loss of revenue. Since the vulnerability requires some level of privilege, insider threats or compromised low-privilege accounts could be leveraged to exploit this flaw. The lack of vendor response and absence of patches increases the urgency for organizations to implement compensating controls. Given the remote exploitability and no user interaction needed, the threat could be leveraged in automated attacks targeting vulnerable installations.

1. Immediate mitigation should include restricting network access to the ZKEACMS administrative interfaces to trusted IP addresses only, minimizing exposure to remote attackers. 2. Implement strict access control policies and monitor for unusual deletion requests or URL redirection changes in logs. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized POST requests to the vulnerable Delete endpoint. 4. Conduct a thorough audit of user privileges and remove or limit low-privilege accounts that have access to the URL redirection management functions. 5. If possible, temporarily disable the URL redirection deletion functionality or replace it with manual processes until a patch is available. 6. Monitor threat intelligence sources for any emerging exploits and vendor updates. 7. Consider deploying intrusion detection systems (IDS) to alert on suspicious activity related to the CMS. 8. Plan for an upgrade or patch deployment once the vendor releases a fix or consider migrating to alternative CMS platforms with active security support.
