CVE-2025-55043 is a CSRF vulnerability identified in MuraCMS, a content management system, affecting versions through 10.1.10. The vulnerability resides in the createBundle method of the csettings.cfc component, which handles the creation of site bundles containing comprehensive site data. Due to insufficient CSRF protections, an attacker can craft a malicious request that, when executed by an authenticated administrator's browser, forces the creation and saving of these bundles without the administrator's consent or awareness. These bundles include sensitive information such as user credentials, password hashes, form data, email lists, plugins, and site content. The bundles are saved to web-accessible directories, making them retrievable by attackers directly via HTTP requests. The attack vector requires no authentication from the attacker and no user interaction beyond the administrator visiting a malicious page or clicking a crafted link. This silent exploitation means administrators remain unaware of the data exfiltration. The vulnerability poses a critical risk to confidentiality and integrity of the affected systems and their data. No official CVSS score has been assigned, but the impact is severe given the breadth of data exposed and the ease of exploitation. No patches or mitigations are currently linked, indicating the need for immediate defensive measures by administrators.

The impact of CVE-2025-55043 is significant for organizations using MuraCMS, as it allows attackers to exfiltrate highly sensitive data including user accounts, password hashes, and other confidential site content without detection. This can lead to credential compromise, unauthorized access, data breaches, and potential downstream attacks such as privilege escalation or lateral movement. The silent nature of the attack means organizations may remain unaware of the breach for extended periods, increasing the risk of extensive data loss and reputational damage. Additionally, exposure of plugins and form submissions could reveal business logic or customer data, further exacerbating the impact. Organizations relying on MuraCMS for critical web presence or data management face a high risk of confidentiality loss and operational disruption if exploited. The vulnerability affects all installations up to version 10.1.10, potentially impacting a broad user base worldwide.

To mitigate CVE-2025-55043, organizations should immediately implement the following measures: 1) Restrict administrative access to trusted networks and IP addresses to reduce exposure to CSRF attacks. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF attempts targeting the bundle creation endpoint. 3) Enforce strict Content Security Policy (CSP) and SameSite cookie attributes to limit cross-origin requests that can trigger CSRF. 4) Educate administrators to avoid clicking on untrusted links or visiting suspicious websites while logged into the CMS. 5) Regularly audit web directories for unexpected bundle files and remove any unauthorized data exposures. 6) Monitor server logs for anomalous requests to the bundle creation functionality. 7) If possible, disable or restrict the bundle creation feature until an official patch or update is released. 8) Engage with MuraCMS vendors or community to obtain patches or updates addressing this vulnerability. These targeted actions go beyond generic advice by focusing on reducing attack surface, detecting exploitation attempts, and limiting data exposure.
