CVE-2025-11069 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of westboy's CicadasCMS, specifically within the Add Department Handler component located in the /system/org/save file. The vulnerability arises from improper sanitization or validation of the 'Name' argument, allowing an attacker to inject malicious scripts. This flaw can be exploited remotely without authentication, although it requires user interaction to trigger the malicious payload. The vulnerability has a CVSS 4.8 score, indicating a medium severity level. The CVSS vector indicates the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:H suggests high privileges but the description says no authentication needed, so this might be a discrepancy), and user interaction is required (UI:P). The impact on confidentiality is none, integrity is low, and availability is none. The vulnerability does not affect system confidentiality or availability but can lead to limited integrity compromise through script execution in the context of the victim's browser. No known exploits are currently observed in the wild, and no patches have been published yet. The public disclosure of the exploit increases the risk of exploitation by attackers targeting vulnerable CicadasCMS installations.

For European organizations using CicadasCMS 1.0, this XSS vulnerability could allow attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, defacement, or redirection to malicious sites. While the direct impact on core system confidentiality and availability is limited, the exploitation could facilitate further attacks such as phishing or privilege escalation if combined with other vulnerabilities. Organizations in sectors with high reliance on web content management systems, such as government, education, and media, may face reputational damage and user trust erosion. Additionally, regulatory frameworks like GDPR impose strict requirements on protecting user data and preventing unauthorized access, so exploitation of this vulnerability could lead to compliance issues and potential fines if personal data is compromised.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include applying strict input validation and output encoding on the 'Name' parameter within the Add Department Handler, either by customizing the CMS code or using web application firewalls (WAFs) with rules to detect and block XSS payloads targeting this endpoint. Organizations should also enforce Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of injected scripts. Regularly monitoring web server logs for suspicious requests to /system/org/save can help detect exploitation attempts. It is critical to upgrade to a patched version once available and to conduct security testing on all web-facing components. User awareness training to recognize phishing attempts that may leverage this vulnerability is also recommended.
