CVE-2024-37765 is an authenticated Blind SQL injection vulnerability identified in Machform, a popular online form builder software, affecting versions up to 19. The flaw resides in the user account settings page, where insufficient input sanitization allows an authenticated user to inject SQL queries that are not directly visible but can be inferred through application behavior (blind SQLi). This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The attacker must have valid credentials (low privilege) but does not require additional user interaction to exploit the flaw. The CVSS v3.1 score of 8.8 reflects the network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability. Exploiting this vulnerability could allow an attacker to extract sensitive data, modify or delete database contents, or disrupt service availability. Although no public exploits are known yet and no official patches have been released, the vulnerability's presence in a widely used form management platform poses a significant risk. Organizations relying on Machform should be aware of this threat and take proactive steps to mitigate risk until a patch is available.

The potential impact of CVE-2024-37765 is severe for organizations using Machform. Successful exploitation can lead to unauthorized disclosure of sensitive data stored in the backend database, including user credentials, form submissions, and configuration details. Attackers could alter or delete data, compromising data integrity and potentially disrupting business operations. Availability could also be affected if the attacker executes destructive SQL commands or causes database corruption. Since the vulnerability requires authentication but no user interaction, insider threats or compromised accounts could be leveraged to escalate attacks. This could lead to data breaches, regulatory non-compliance, reputational damage, and financial losses. Organizations that use Machform for critical data collection or customer-facing forms are particularly at risk. The lack of a patch increases the urgency for interim mitigations to prevent exploitation.

To mitigate CVE-2024-37765, organizations should implement the following specific measures: 1) Restrict user privileges strictly to the minimum necessary, especially for accounts with access to the user account settings page. 2) Monitor application and database logs for unusual query patterns or repeated failed attempts indicative of SQL injection probing. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the user account settings functionality. 4) Enforce strong authentication and session management to reduce the risk of credential compromise. 5) Conduct internal code reviews and penetration testing focused on the user account settings page to identify and remediate injection points. 6) Prepare for rapid patch deployment once an official fix is released by the vendor. 7) Consider isolating the Machform application environment to limit lateral movement in case of compromise. 8) Educate users about the importance of safeguarding credentials to prevent unauthorized access. These steps go beyond generic advice by focusing on privilege restriction, monitoring, and proactive detection tailored to this vulnerability's characteristics.
