CVE-2025-66944: Databaseir SQL Injection Vulnerability

CVE-2025-66944 Overview

CVE-2025-66944 is a SQL Injection vulnerability affecting vran-dev databasir version 1.0.7 and earlier. This vulnerability allows a remote attacker to execute arbitrary code by exploiting the query parameter in the search API endpoint. As a classic SQL injection flaw, attackers can manipulate database queries to extract sensitive data, modify database contents, or potentially gain complete control over the underlying system.

Critical Impact

This SQL Injection vulnerability enables unauthenticated remote attackers to execute arbitrary database commands, potentially leading to complete data breach, data manipulation, or system compromise.

Affected Products

• vran-dev databasir v.1.0.7
• vran-dev databasir versions prior to v.1.0.7

Technical Details for CVE-2025-66944

Vulnerability Analysis

This vulnerability is classified as CWE-89: Improper Neutralization of Special Elements used in an SQL Command (SQL Injection). The flaw exists in the search API endpoint of the databasir application, where user-supplied input through the query parameter is not properly sanitized before being incorporated into SQL queries.

SQL Injection vulnerabilities of this nature allow attackers to inject malicious SQL statements that the database server will execute. Since the vulnerability requires no authentication and can be exploited remotely over the network with low complexity, it presents a significant risk to organizations running affected versions of databasir.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization in the search API endpoint. The application fails to properly escape or parameterize user input from the query parameter before constructing SQL queries. This allows attackers to break out of the intended query structure and inject arbitrary SQL commands that the database will execute with the application's privileges.

Attack Vector

The attack can be carried out remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the search API endpoint, embedding SQL injection payloads in the query parameter. Successful exploitation could allow the attacker to:

• Extract sensitive data from the database including credentials and application data
• Modify or delete database records
• Execute administrative operations on the database
• Potentially achieve remote code execution depending on database configuration and privileges

The vulnerability is documented in the GitHub Issue Discussion and additional technical analysis is available in the ZeroDay Blog Post on CVE-2025-66944.

Detection Methods for CVE-2025-66944

Indicators of Compromise

• Unusual or malformed requests to the search API endpoint containing SQL syntax characters (single quotes, semicolons, UNION statements, comment sequences)
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or query patterns in database audit logs
• Evidence of data exfiltration or unauthorized database access

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in API requests
• Enable detailed logging for the search API endpoint and monitor for anomalous query patterns
• Deploy database activity monitoring to identify suspicious queries or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor application logs for repeated failed requests or error messages related to SQL queries
• Set up alerts for unusual database query patterns or query execution times
• Track API endpoint access patterns for anomalous behavior such as high request volumes or unusual source IPs
• Implement database audit logging to capture all queries executed against sensitive tables

How to Mitigate CVE-2025-66944

Immediate Actions Required

• Upgrade vran-dev databasir to a patched version when available
• Implement input validation and parameterized queries as a defense-in-depth measure
• Deploy a Web Application Firewall (WAF) to filter malicious requests targeting the search API endpoint
• Restrict network access to the application to trusted sources where possible
• Review database permissions and apply principle of least privilege

Patch Information

Users should monitor the official databasir GitHub repository for security updates and patches addressing this vulnerability. Upgrade to the latest version once a fix is released. Review the vendor's security advisories for specific remediation guidance.

Workarounds

• Disable or restrict access to the search API endpoint if it is not critical to operations
• Implement network-level access controls to limit which users and systems can reach the vulnerable endpoint
• Deploy application-level input validation to reject requests containing SQL injection patterns
• Use a reverse proxy or WAF configured to block requests with malicious payloads targeting the query parameter

# Example WAF rule to block common SQL injection patterns (ModSecurity syntax)
SecRule ARGS:query "@rx (?i)(union|select|insert|update|delete|drop|;|--|')" \
