A SQL injection vulnerability in RimbaLinux AhadPOS 1.11 allows authenticated attackers to execute unauthorized database queries, potentially leading to information disclosure.

The application is susceptible to time-based and boolean-based blind SQL injection via the alamatCustomer and barcode parameters. This vulnerability requires the attacker to be authenticated to the application to trigger the malicious POST requests.

Successful exploitation of this vulnerability allows an attacker to extract sensitive data from the underlying database or manipulate application logic. Given the CVSS score of 7.1, this is a high-severity flaw that could lead to unauthorized access to customer records or point-of-sale data, resulting in significant reputational damage and potential regulatory non-compliance.

Immediate Action: As no official patch is currently available, users should restrict access to the application to trusted networks only and implement strict input validation for the alamatCustomer and barcode parameters.

Proactive Monitoring: Security teams should monitor database access logs for anomalous behavior, such as excessive query times or unexpected SQL syntax errors, which may indicate blind SQL injection attempts.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block SQL injection patterns, such as the use of SLEEP functions or boolean logic manipulation in POST parameters.

Public Exploit Available: Yes, a public proof-of-concept exists in the form of an Exploit-DB entry (EDB-ID 47585).

The presence of a public proof-of-concept significantly lowers the barrier for exploitation. Organizations currently utilizing RimbaLinux AhadPOS 1.11 must prioritize the implementation of compensating controls, such as WAF rules and network segmentation, to mitigate the risk until an official vendor update is released.
