CVE-2024-54879 is a critical security vulnerability identified in SeaCMS version 13.1, a content management system platform. The vulnerability arises from an incorrect access control logic flaw, classified under CWE-281, which allows unauthorized users to exploit the recharge functionality intended for members. Specifically, the flaw permits any user, including unauthenticated attackers, to perform unlimited recharge operations on member accounts without restriction. This bypasses intended authorization checks, compromising the integrity and confidentiality of the system's financial or credit-related data. The vulnerability has a CVSS 3.1 base score of 9.1, reflecting its critical severity, with an attack vector that is network-based (AV:N), requiring no privileges (PR:N) and no user interaction (UI:N). The scope is unchanged (S:U), and the impact is high on confidentiality and integrity but none on availability. No patches or mitigations have been officially published yet, and there are no known active exploits in the wild. The flaw could be exploited remotely by attackers to fraudulently increase member balances or credits indefinitely, potentially leading to financial losses and undermining trust in the platform. The lack of authentication requirements makes this vulnerability particularly dangerous, as it can be exploited by any external actor with network access to the system.

The impact of CVE-2024-54879 is significant for organizations using SeaCMS 13.1, especially those relying on the member recharge functionality for financial transactions or credit management. Unauthorized recharge operations can lead to direct financial losses, fraudulent activities, and erosion of customer trust. The integrity of member account data is compromised, as attackers can manipulate balances without detection. Confidential information related to member transactions may also be exposed or altered. While availability is not affected, the reputational damage and potential regulatory consequences from financial fraud could be severe. Organizations may face challenges in auditing and reconciling member accounts due to unauthorized recharge events. The vulnerability's ease of exploitation without authentication increases the risk of widespread abuse, potentially impacting multiple organizations globally that deploy SeaCMS 13.1 in their environments.

To mitigate CVE-2024-54879, organizations should immediately implement strict access control measures around the member recharge functionality. This includes enforcing robust authentication and authorization checks to ensure only legitimate, authorized users can perform recharge operations. Network-level protections such as firewalls and intrusion detection systems should be configured to monitor and restrict access to recharge endpoints. Organizations should conduct thorough code reviews and penetration testing focused on access control logic within SeaCMS. Until an official patch is released, consider disabling or restricting the recharge feature to trusted internal users only. Implement detailed logging and monitoring of recharge transactions to detect anomalous or excessive activity promptly. Additionally, applying web application firewalls (WAFs) with custom rules to block unauthorized recharge attempts can provide a temporary safeguard. Engage with SeaCMS vendors or community for updates and patches, and prepare incident response plans to address potential exploitation scenarios.
