CVE-2024-45771 is a critical SQL injection vulnerability identified in RapidCMS version 1.3.1. The flaw exists in the password parameter of the /resource/runlogin.php endpoint, allowing attackers to inject malicious SQL code. This vulnerability is exploitable remotely without any authentication or user interaction, making it highly accessible to attackers. The injection flaw can lead to unauthorized data access, data modification, or deletion, and potentially full system compromise if the database backend is leveraged to execute further commands. The vulnerability is categorized under CWE-89, which is a well-known class of injection flaws where untrusted input is improperly sanitized before being included in SQL queries. The CVSS 3.1 base score of 9.8 indicates critical severity, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits have been reported yet, the vulnerability's characteristics suggest it could be weaponized quickly. RapidCMS is a content management system, and exploitation could lead to exposure or manipulation of sensitive content, user credentials, or administrative controls. The lack of available patches at the time of disclosure increases the urgency for organizations to implement interim mitigations.

The impact of CVE-2024-45771 is severe for organizations using RapidCMS 1.3.1. Successful exploitation can lead to complete compromise of the CMS database, exposing sensitive user data, administrative credentials, and proprietary content. Attackers could modify or delete data, disrupt service availability, or pivot to other internal systems if the CMS is integrated within a larger network. The vulnerability’s remote, unauthenticated nature means attackers can exploit it without prior access, increasing the risk of widespread attacks. Organizations relying on RapidCMS for public-facing websites or internal portals face reputational damage, regulatory penalties due to data breaches, and operational disruptions. The absence of known exploits currently provides a narrow window for proactive defense, but the critical severity and ease of exploitation make rapid response essential to prevent potential breaches.

To mitigate CVE-2024-45771, organizations should immediately assess their use of RapidCMS version 1.3.1 and restrict access to the /resource/runlogin.php endpoint where possible. Since no official patches are currently available, implement the following specific measures: 1) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the password parameter; 2) Conduct input validation and sanitization on all user-supplied data, especially the password field, using allowlists and parameterized queries or prepared statements if modifying source code is feasible; 3) Monitor database logs and application logs for unusual queries or failed login attempts indicative of injection attempts; 4) Limit database user privileges associated with the CMS to the minimum necessary to reduce potential damage; 5) Isolate the CMS environment from critical internal networks to contain potential breaches; 6) Stay alert for official patches or updates from RapidCMS developers and apply them promptly once released; 7) Educate security teams about this vulnerability to ensure rapid detection and response to suspicious activity.
