This rule detects attempts to extract credentials from FortiGate devices by targeting specific management API endpoints. It looks for HTTP GET requests to '/api/v2/cmdb/' followed by paths like 'system/admin', 'vpn.ssl.settings', or 'user/local', which are known to contain sensitive configuration or user data. This activity is associated with the 'FortiBleed' campaign and CVE-2026-24858.

This rule monitors incoming HTTP requests for classic SQL injection patterns, such as UNION SELECT, SLEEP, BENCHMARK, and various SQL commands like DROP or ALTER. These signatures are commonly associated with attempts to gain unauthorized access to database contents, exfiltrate data, or compromise the database integrity via web applications.

Detects incoming HTTP traffic attempting to exploit the Apache Struts2 vulnerability CVE-2017-5638. The rule monitors the Content-Type HTTP header for OGNL (Object-Graph Navigation Language) expressions containing known exploitation markers like ClassLoader, getRuntime, or .exec(), which indicate an attempt to achieve Remote Code Execution (RCE).

Detects Server-Side Request Forgery (SSRF) attempts targeting Microsoft Exchange via the /autodiscover/ endpoint. The attack leverages a specifically crafted X-BEResource header containing an internal IP address, which is indicative of the CVE-2021-26855 vulnerability used in ProxyLogon exploitation.

This rule detects HTTP POST requests targeting Cisco Firepower Management Center (FMC) that contain Java exploitation patterns (Runtime.getRuntime or ProcessBuilder) associated with the exploitation of CVE-2026-20131. This activity is indicative of an attempt to achieve Remote Code Execution (RCE) on the FMC appliance, likely by an actor utilizing the Interlock Ransomware threat.

Detects common SQL injection patterns within the HTTP URI query string. The rule monitors established network traffic to web servers and uses regex matching to identify attempts to use SQL keywords like UNION SELECT, OR 1=1 boolean-based attacks, blind SQL injection techniques (sleep/benchmark), and attempts to access information_schema metadata tables.

This rule detects attempts to exploit the Log4Shell vulnerability (CVE-2021-44228) by monitoring HTTP headers (User-Agent, X-Forwarded-For, Referer) for JNDI lookup strings. The JNDI lookup mechanism in vulnerable Log4j libraries allows an attacker to execute arbitrary code by pointing the lookup to a malicious LDAP, RMI, or DNS server.
