A critical SQL injection vulnerability (CVE-2025-43949) has been identified in MuM MapEdit version 24.2.3, posing significant risk to organizations using this web application. The vulnerability, rated 9.8 (CRITICAL) on the CVSS scale, allows remote attackers to execute arbitrary SQL commands without authentication. First reported on April 22, 2025, this flaw affects the database interface component of the mapedit-web application.
Technical Overview
The vulnerability stems from improper neutralization of SQL commands (CWE-89) in the web application’s database interface. Attackers can exploit this weakness remotely without requiring authentication (CVSS 3.1: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Successful exploitation could lead to complete compromise of the database server, including data theft, modification, or deletion. The affected component is part of the core functionality that processes user-supplied input before database queries.
According to multiple sources including NVD and GitHub Advisory, the vulnerability was discovered through automated testing by Henkel-CyberVM. The attack vector is particularly dangerous because it doesn’t require any special privileges or user interaction. The vulnerability affects all deployments of MapEdit 24.2.3, which was the current stable release at the time of discovery.
Impact and Severity
The CVSS 3.1 score of 9.8 reflects the maximum impact across all metrics. The vulnerability scores high in both exploitability and impact dimensions, with complete compromise of confidentiality, integrity, and availability. Organizations using vulnerable versions could face complete database compromise, potentially exposing sensitive mapping data and system credentials.
Tenable’s analysis suggests that exploitability is likely, given the nature of the vulnerability and the prevalence of SQL injection techniques in the wild. The EPSS score from NoHackMe indicates high risk of active exploitation attempts in the near future. As of April 23, 2025, no official patch has been released by MuM, though security researchers are monitoring the vendor’s response.
Mitigation Strategies
While awaiting an official patch, organizations should implement these immediate workarounds:
- Implement strict input validation for all user-supplied data
- Convert existing queries to parameterized statements
- Restrict database permissions to minimum required levels
- Monitor for unusual database activity patterns
Security teams should pay particular attention to web application firewall logs for SQL injection attempts. Network segmentation can help limit potential lateral movement if the database is compromised. Regular database backups should be verified and stored securely in case restoration becomes necessary.
Detection and Monitoring
Organizations can detect potential exploitation attempts by monitoring for unusual SQL query patterns in database logs. Specific indicators include:
- Unexpected UNION statements in queries
- Presence of SQL comment sequences (– or /* */) in input fields
- Abnormal database error messages containing SQL syntax
Security teams should review existing detection rules for SQL injection and ensure they cover the specific patterns associated with this vulnerability. Network monitoring solutions should be configured to alert on suspicious database access patterns, particularly from web application servers.
Conclusion
CVE-2025-43949 represents a serious threat to organizations using MuM MapEdit 24.2.3. The critical severity rating and remote exploitability make this vulnerability particularly dangerous. While no patch is currently available, implementing the recommended workarounds can significantly reduce risk. Security teams should monitor vendor communications for updates and be prepared to apply patches immediately when released.
The discovery of this vulnerability highlights the ongoing importance of secure coding practices, particularly proper input validation and parameterized queries. Organizations should consider this event as an opportunity to review their application security testing procedures and ensure proper coverage for SQL injection vulnerabilities across all web applications.
