CVE-2024-22699 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability identified in FlyCms version 1.0. The vulnerability exists in the endpoint /system/admin/update_group_save, which is likely responsible for managing administrative group settings within the CMS. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request, which can lead to unauthorized actions being performed on behalf of the user without their consent. In this case, the vulnerability could enable an attacker to modify administrative group configurations, potentially escalating privileges or altering access controls. The CVSS 3.1 base score of 8.8 reflects a high impact on confidentiality, integrity, and availability, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no patches or known exploits in the wild are currently reported, the vulnerability poses a significant risk due to the sensitive nature of administrative functions it affects. The lack of vendor or product information beyond FlyCms v1.0 limits detailed attribution but does not diminish the threat posed by this vulnerability.

For European organizations using FlyCms v1.0, this vulnerability could have severe consequences. Successful exploitation could lead to unauthorized modification of administrative groups, potentially allowing attackers to escalate privileges, create or modify user roles, or disrupt administrative controls. This could result in data breaches, unauthorized access to sensitive information, or disruption of CMS operations. Given that FlyCms is a content management system, compromised administrative controls could also lead to website defacement, injection of malicious content, or further pivoting into internal networks. The high confidentiality, integrity, and availability impacts mean that organizations could face regulatory repercussions under GDPR if personal data is exposed or integrity is compromised. Additionally, operational disruptions could affect business continuity and reputation. The requirement for user interaction means phishing or social engineering could be used as attack vectors, increasing risk in environments with less security awareness.

To mitigate this vulnerability, European organizations should first identify all instances of FlyCms v1.0 in their environment. Since no official patches are currently available, organizations should implement compensating controls immediately. These include enforcing strict anti-CSRF tokens on all state-changing requests, especially on the /system/admin/update_group_save endpoint. Web Application Firewalls (WAFs) should be configured to detect and block suspicious CSRF patterns or anomalous requests targeting administrative endpoints. Organizations should also enhance user awareness training to reduce the risk of social engineering attacks that could trigger CSRF exploits. Network segmentation and strict access controls limiting administrative interface exposure to trusted networks or VPNs can reduce attack surface. Monitoring and logging of administrative actions should be intensified to detect unauthorized changes promptly. Once a vendor patch is released, organizations must prioritize timely deployment. Additionally, conducting regular security assessments and penetration testing focused on CSRF and related vulnerabilities will help identify and remediate similar issues proactively.
