SQLi in Abis Technology's BAPSIS

The SQL Injection vulnerability in BAPSIS allows an attacker to bypass application security measures and directly interact with the underlying database. Due to the 'blind' nature of the injection, the attacker doesn't receive immediate feedback from the database, requiring techniques like time-based or boolean-based injection to extract data. Successful exploitation could lead to the theft of sensitive data such as user credentials, financial records, or other confidential information stored within the BAPSIS database. Lateral movement within the network is possible if the database user has elevated privileges, potentially allowing the attacker to compromise other systems. The blast radius extends to all data accessible by the vulnerable database user.

Organizations utilizing BAPSIS for their business processes, particularly those handling sensitive data like financial or personal information, are at significant risk. Deployments with weak database user permissions or those lacking robust input validation mechanisms are especially vulnerable. Shared hosting environments where multiple BAPSIS instances reside on the same server could also experience cascading impacts if one instance is compromised.

• linux / server: Monitor database logs (e.g., /var/log/mysql/error.log) for SQL queries containing suspicious characters like ' or ;. Use auditd to track database access and identify unusual query patterns.

auditctl -w /var/log/mysql/error.log -p wa -k mysql_injection

• database (mysql): Use mysql -e to test for SQL injection vulnerabilities. Be cautious and only test in a controlled environment.

mysql -u <user> -p'<test_string>' -e 'SELECT 1' --disable-column-names

• generic web: Use curl to test endpoints for SQL injection by injecting malicious payloads into input fields.

curl 'http://<bapsis_url>/<vulnerable_endpoint>?param=<sql_injection_payload>'

The primary mitigation for CVE-2025-6520 is to immediately upgrade BAPSIS to version 202510271606 or later. If upgrading is not immediately feasible, consider implementing temporary workarounds such as input validation and parameterized queries on the application layer to prevent SQL injection attacks. Web application firewalls (WAFs) configured with rules to detect and block SQL injection attempts can provide an additional layer of defense. Monitor database logs for suspicious activity, specifically queries containing unusual characters or patterns indicative of SQL injection attempts. After upgrading, confirm the fix by attempting a known SQL injection payload against the application and verifying that it is properly sanitized.
