CVE-2023-52073 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability identified in FlyCms version 1.0. The vulnerability exists in the component located at /system/site/config_footer_updagte, which appears to be responsible for updating footer configuration settings within the CMS. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a unwanted request to the web application, potentially causing unauthorized actions without the user's consent. In this case, the vulnerability could allow an attacker to modify critical site configuration parameters, impacting the confidentiality, integrity, and availability of the affected system. The CVSS 3.1 base score of 8.8 reflects the high impact and ease of exploitation: the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The vulnerability affects the confidentiality, integrity, and availability of the system (C:H/I:H/A:H), meaning an attacker could fully compromise the system by leveraging this CSRF flaw. Although no known exploits are currently reported in the wild, the lack of a patch or mitigation guidance increases the risk for organizations using FlyCms 1.0. The CWE-352 classification confirms the nature of the vulnerability as a CSRF issue. Given the component affected is related to site configuration, successful exploitation could lead to persistent unauthorized changes, potentially enabling further attacks such as privilege escalation or data exfiltration.

For European organizations using FlyCms 1.0, this vulnerability poses a significant risk. Unauthorized modification of site configuration could lead to defacement, insertion of malicious scripts, or disruption of service, impacting brand reputation and customer trust. Confidential data managed by the CMS could be exposed or altered, violating GDPR and other data protection regulations, leading to legal and financial penalties. The high severity and network accessibility mean attackers could exploit this vulnerability remotely, increasing the attack surface. Organizations in sectors such as government, finance, healthcare, and e-commerce, which rely heavily on web content management systems, are particularly vulnerable. The potential for widespread impact is amplified if FlyCms is integrated with other internal systems or handles sensitive user data. Additionally, the requirement for user interaction (e.g., an authenticated administrator visiting a malicious link) means social engineering could be leveraged to facilitate attacks, increasing the risk of successful exploitation.

Immediate mitigation steps include implementing anti-CSRF tokens in all state-changing requests within FlyCms, especially for the /system/site/config_footer_updagte endpoint. Organizations should review and restrict user permissions to minimize the number of users with configuration modification rights. Employing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide an additional layer of defense. Administrators should educate users about the risks of clicking on untrusted links while authenticated to the CMS. Network segmentation and limiting administrative access to trusted IP addresses can reduce exposure. Since no official patch is currently available, organizations should consider temporarily disabling or restricting access to the vulnerable component if feasible. Monitoring logs for unusual configuration changes or access patterns can help detect exploitation attempts early. Finally, organizations should maintain regular backups of configuration data to enable rapid recovery if unauthorized changes occur.
