CVE-2024-56116 is a Cross-Site Request Forgery (CWE-352) vulnerability affecting Amiro.CMS versions before 7.8.4. This vulnerability allows remote attackers to create administrator accounts without requiring prior authentication, by exploiting the lack of proper CSRF protections in the CMS. An attacker can craft a malicious web request that, when executed by an authenticated user (with sufficient privileges), results in the creation of a new administrator account controlled by the attacker. The vulnerability is classified with a CVSS 3.1 base score of 8.8, indicating high severity, with attack vector being network-based, low attack complexity, no privileges required, but user interaction necessary. The impact covers confidentiality, integrity, and availability, as unauthorized administrative access can lead to full system compromise, data theft, defacement, or denial of service. Although no known exploits have been reported in the wild yet, the vulnerability poses a significant risk due to the critical nature of administrative access and the ease of exploitation through social engineering or malicious web content. No official patches or mitigation links are currently provided, but upgrading to version 7.8.4 or later is implied to resolve the issue. Amiro.CMS is a content management system primarily used in Russian-speaking markets, which influences the geographic risk profile.

The vulnerability allows attackers to gain unauthorized administrative access to affected Amiro.CMS installations, which can lead to complete system takeover. This compromises the confidentiality of sensitive data stored or managed by the CMS, including user information and proprietary content. Integrity is severely impacted as attackers can modify or delete content, inject malicious code, or create backdoors. Availability may also be affected if attackers disrupt CMS operations or deploy ransomware. Organizations relying on Amiro.CMS for their web presence or internal portals face reputational damage, operational disruption, and potential regulatory penalties if data breaches occur. The ease of exploitation via CSRF and the lack of required authentication increase the risk of widespread attacks, especially if attackers leverage phishing or social engineering to induce user interaction. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the threat remains critical due to the high potential impact.

1. Immediately upgrade Amiro.CMS installations to version 7.8.4 or later once available, as this version addresses the CSRF vulnerability. 2. Implement web application firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting Amiro.CMS endpoints. 3. Enforce strict Content Security Policy (CSP) headers to reduce the risk of malicious cross-site requests. 4. Educate users, especially administrators, about the risks of clicking on untrusted links or visiting suspicious websites to mitigate social engineering vectors. 5. Monitor web server and application logs for unusual account creation activities or anomalous administrative actions. 6. Employ multi-factor authentication (MFA) for administrative accounts to add an additional layer of security even if account creation is compromised. 7. Disable or restrict administrative account creation features via the CMS configuration if not required. 8. Conduct regular security assessments and penetration testing focused on CSRF and privilege escalation vectors. 9. Prepare incident response plans specifically addressing CMS compromise scenarios to enable rapid containment and recovery.
