This rule is designed to detect the usage of the sqlmap user agent string within application monitoring logs, specifically targeting unauthorized web clients. Sqlmap is an open-source tool often used to exploit SQL injection vulnerabilities in web applications. The detection mechanism identifies instances of the user agent 'sqlmap/1.3.11#stable', which may indicate suspicious testing activity. In light of the potential impact of sqlmap if used maliciously, the rule flags such activities, allowing security teams to investigate further. The rule emphasizes a proactive approach by outlining investigation steps that involve a thorough review of logs and potentially blocking unwanted IP addresses. It also provides a comprehensive false positive analysis to help security teams distinguish between legitimate security assessments and genuine threats, ensuring that internal security testing does not trigger unnecessary alerts. Lastly, it suggests a standardized response protocol to mitigate risks associated with the exploitation of SQL injection vulnerabilities if a real threat is determined.
