CVE-2025-54541 is a Cross-Site Request Forgery (CSRF) vulnerability identified in OpenSolution's QuickCMS version 6.8. The vulnerability affects the page deletion functionality, allowing an attacker to craft a malicious website that, when visited by an authenticated administrator, automatically triggers a POST request to delete an article without the admin's consent or knowledge. This attack exploits the lack of proper anti-CSRF protections such as tokens or origin checks in the affected CMS version. The vendor was notified early but did not disclose detailed information about the vulnerability or the full range of affected versions. Only version 6.8 has been confirmed vulnerable through testing, but other versions may also be susceptible. The CVSS 4.0 base score is 6.9 (medium severity), reflecting that the attack can be performed remotely without authentication or user interaction, and it impacts the integrity of the CMS content by unauthorized deletion of articles. The vulnerability does not affect confidentiality or availability directly, but the integrity impact can disrupt website content management and trust. No known exploits are currently reported in the wild, and no patches have been released yet. The vulnerability is classified under CWE-352, which covers CSRF issues where state-changing requests are not protected against unauthorized cross-origin requests.

For European organizations using QuickCMS 6.8, this vulnerability poses a significant risk to the integrity of their web content. An attacker could cause unauthorized deletion of important articles or pages, potentially disrupting business operations, damaging reputation, and causing loss of critical information. Organizations relying on QuickCMS for public-facing websites, intranets, or knowledge bases could experience content tampering that undermines user trust and information reliability. While the vulnerability does not directly compromise confidentiality or availability, the loss or alteration of content could lead to operational downtime and increased recovery costs. Additionally, if exploited in a targeted manner, it could be used as part of a broader attack campaign to undermine organizational communications or spread misinformation. The lack of vendor response and absence of patches increases the urgency for organizations to implement compensating controls.

1. Implement strict anti-CSRF protections: If possible, upgrade to a version of QuickCMS that includes CSRF tokens or origin validation in state-changing requests. Since no patch is currently available, consider applying manual code-level mitigations such as adding CSRF tokens to forms and verifying them server-side. 2. Restrict administrative access: Limit access to the CMS admin interface by IP whitelisting, VPN access, or multi-factor authentication to reduce the risk of an attacker tricking an admin into visiting a malicious site. 3. Educate administrators: Train CMS administrators to avoid visiting untrusted websites while logged into the CMS to minimize the risk of CSRF exploitation. 4. Monitor CMS logs: Implement monitoring to detect unusual deletion activities or repeated POST requests to deletion endpoints. 5. Use web application firewalls (WAFs): Configure WAF rules to detect and block suspicious POST requests that do not originate from legitimate sources. 6. Consider isolating the CMS environment or using reverse proxies to add additional security layers until an official patch is released.
