CVE-2024-41618 identifies a critical SQL Injection vulnerability in Money Manager EX WebApp version 1.2.2, specifically within the transaction_delete_group function. The vulnerability stems from improper sanitization of the TrDeleteArr parameter, which is incorporated directly into an SQL query without any validation or parameterization. This flaw allows remote attackers to inject malicious SQL code, potentially enabling them to manipulate the database, extract sensitive financial data, modify or delete records, or even execute administrative commands on the backend database server. The vulnerability requires no authentication or user interaction, making it trivially exploitable over the network. The CVSS 3.1 base score of 9.8 indicates a critical severity level, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact scope is unchanged (S:U), but confidentiality, integrity, and availability impacts are all high (C:H/I:H/A:H). Although no public exploits have been reported yet, the nature of SQL Injection vulnerabilities and the criticality of this one suggest that exploitation could lead to full compromise of the affected system's data and potentially the underlying infrastructure. The vulnerability is categorized under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). No patches or mitigations have been linked yet, emphasizing the need for immediate attention from users of this software. Organizations relying on Money Manager EX WebApp for financial management should consider applying input validation, using prepared statements, or isolating the vulnerable component until an official patch is released.

The impact of CVE-2024-41618 is severe for organizations using Money Manager EX WebApp 1.2.2. Successful exploitation can lead to complete compromise of the application's database, exposing sensitive financial data such as transaction records, user credentials, and other confidential information. Attackers could modify or delete financial data, causing data integrity issues and potential financial losses. The vulnerability also threatens availability, as attackers could disrupt services by deleting or corrupting critical data. Given the lack of authentication and user interaction requirements, attackers can remotely exploit this vulnerability at scale, increasing the risk of widespread data breaches. Organizations in finance, personal budgeting, and small business sectors using this software are particularly vulnerable. The breach of financial data can lead to regulatory penalties, reputational damage, and loss of customer trust. Additionally, attackers might leverage this access as a foothold for further network intrusion or lateral movement within an organization’s infrastructure.

To mitigate CVE-2024-41618, organizations should immediately implement the following measures: 1) Apply any available patches or updates from the Money Manager EX WebApp developers as soon as they are released. 2) If patches are not yet available, restrict network access to the vulnerable web application, limiting it to trusted internal users only. 3) Implement Web Application Firewall (WAF) rules to detect and block SQL Injection attack patterns targeting the TrDeleteArr parameter. 4) Conduct code review and refactor the transaction_delete_group function to use parameterized queries or prepared statements, ensuring proper input sanitization and escaping. 5) Employ database least privilege principles, ensuring the application database user has minimal permissions to limit the impact of a successful injection. 6) Monitor application logs and database logs for suspicious queries or anomalies indicative of exploitation attempts. 7) Educate developers and administrators about secure coding practices to prevent similar vulnerabilities in the future. 8) Consider isolating the vulnerable service in a segmented network zone to reduce potential lateral movement if compromised.
