This rule detects attempts to exploit a path traversal vulnerability (CVE-2024-21762) in FortiOS SSL-VPN by monitoring for malformed GET requests targeting the /remote/fgt_lang endpoint. The rule also tracks successful exploitation by identifying HTTP 200 responses containing Linux password file patterns (root:x:0:0:), indicating potential remote file disclosure.

Detects indicators associated with the exploitation of CVE-2025-3248 in Langflow. The rule identifies anomalous web requests targeting the /api/v1/validate/code endpoint, subsequent suspicious process creation (base64 encoded payloads in Python/shell), and network communication with identified command and control (C2) or data exfiltration IP addresses. It also includes alerts for observed contact with known extortion email addresses.

This rule monitors IT asset inventory data for instances of ConnectWise (ScreenConnect) software running outdated versions prior to 26.6.5, which are known to be vulnerable to CVE-2026-84869. Identifying these assets is critical for preventing potential exploitation of public-facing remote administration tools.

This rule detects potential exploitation attempts against PaperCut servers by identifying high-frequency, consistent-interval network requests directed at PaperCut-specific URI patterns and ports, or associated with known vulnerability identifiers (CVE-2026-81578, CVE-2026-82078). The rule employs statistical analysis to identify potential automated scanning or exploitation activity, filtering out known geographic regions associated with lower-risk or irrelevant traffic.

Detects unauthenticated network requests targeting specific administration endpoints (SetupCompleted, configure-update-service, or /admin/) of PaperCut NG/MF applications. The rule identifies potential exploitation attempts by flagging successful requests that return HTTP status codes other than 401 (Unauthorized) or 403 (Forbidden), indicating a possible authentication bypass.

Detects potential JWT algorithm-confusion or authentication-bypass attempts
targeting WSO2 API Manager components through JWTs specifying unsupported,
downgraded, or unexpected signing algorithms such as "none" or HS256 where
asymmetric signing is expected. Matching events should be investigated to
determine whether the request represents exploitation of CVE-2026-5430.

Detects rapid, machine-speed, sequential attack-path adaptation by suspected AI agent binaries. The rule monitors for a correlation of four stages occurring within a tight 20-minute window: 1) Failed service connections across three or more distinct protocols (SMB, SSH, HTTP, RDP, WinRM), 2) Credential access attempts (Logon events or execution of known credential-dumping tools), and 3) A lateral movement pivot to a new, previously un-targeted internal destination. The rule specifically keys on the InitiatingProcessId and InitiatingProcessCreationTime to ensure the sequence is attributed to a single process instance, distinguishing it from human manual penetration testing activity. Covers T1190, T1210, T1078

This rule detects inbound HTTP requests targeting Microsoft Exchange Server that contain the specific headers and patterns associated with the ProxyLogon (CVE-2021-26855) Server-Side Request Forgery (SSRF) vulnerability. It specifically monitors for the presence of the 'X-BEResource' header and malformed request structures used by attackers to bypass authentication.

The following analytic identifies unusually long strings in the Content-Type HTTP header sent by the client to the server. It uses data from the Stream:HTTP source, specifically evaluating the length of the `cs_content_type` field. This activity is significant because excessively long Content-Type headers can indicate attempts to exploit vulnerabilities or evade detection mechanisms. If confirmed malicious, this behavior could allow attackers to execute code, manipulate data, or bypass security controls, potentially leading to unauthorized access or data breaches.

This rule detects SQL injection attempts targeting the BuddyBoss members REST endpoint, specifically identifying exploitation patterns associated with the 'sqlmap' tool. The rule monitors for specific URL parameters including 'member_type', 'search_terms', and 'scope' in combination with an 'sqlmap' user-agent, indicating an automated exploitation attempt against the application.

Detects a multi-stage attack pattern against publicly exposed AI service endpoints. The detection correlates: (1) Enumeration of sensitive AI/MCP-related API endpoints (minimum 3 distinct hits) in a 10-minute window; (2) Subsequent POST requests to AI service endpoints within 15 minutes of the enumeration; and (3) A spike of 5 or more server errors (HTTP 5xx) within 10 minutes following the POST activity. This pattern suggests automated reconnaissance followed by attempted exploitation of exposed AI model interfaces or orchestration services. Covers T1595.002, T1190
