CVE-2024-48655 is a critical remote code execution (RCE) vulnerability identified in Total.js CMS version 1.0. The flaw exists in the func.js file, which improperly processes input, allowing an attacker to inject and execute arbitrary JavaScript code on the server. This vulnerability is classified under CWE-94 (Improper Control of Generation of Code), indicating that the system fails to safely handle dynamic code generation or evaluation. The CVSS 3.1 base score of 8.8 reflects its high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this vulnerability could enable attackers to take full control of the affected CMS server, leading to data breaches, defacement, or service disruption. Although no public exploits are currently known, the lack of available patches increases the urgency for defensive measures. The vulnerability affects web servers running Total.js CMS 1.0, which is a Node.js-based content management system used for building web applications and websites. Given the nature of the vulnerability, attackers could remotely execute malicious code, potentially pivoting within the network or stealing sensitive data.

The impact of CVE-2024-48655 is severe for organizations using Total.js CMS 1.0. Successful exploitation allows remote attackers to execute arbitrary code with the privileges of the CMS process, potentially leading to full system compromise. This can result in unauthorized data access, data modification, or deletion, and disruption of web services. Organizations hosting sensitive or critical web applications on Total.js CMS are at risk of data breaches, defacement, ransomware deployment, or lateral movement within their networks. The vulnerability's ease of exploitation and lack of required user interaction make it attractive for attackers. Additionally, the absence of patches means organizations remain exposed until mitigations or updates are applied. This could affect sectors relying on web presence and content management, including e-commerce, government, education, and media.

To mitigate CVE-2024-48655, organizations should immediately audit their use of Total.js CMS and identify any instances of version 1.0 in production. Until an official patch is released, consider the following specific actions: 1) Restrict network access to the CMS backend, limiting it to trusted IP addresses or VPNs to reduce exposure. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting func.js or dynamic code execution attempts. 3) Review and harden server-side configurations to minimize privileges of the CMS process, implementing the principle of least privilege. 4) Monitor logs for unusual activity, especially unexpected code execution or file modifications related to func.js. 5) If feasible, isolate the CMS environment using containerization or sandboxing to limit potential damage. 6) Engage with Total.js maintainers or community to track patch releases and apply updates promptly once available. 7) Consider temporary migration to alternative CMS platforms if risk tolerance is low and patching is delayed.
