Identifies devices running PHP versions affected by CVE-2026-109618 or CVE-2026-109619. The detection returns affected hosts, operating system platform, installed PHP version, and associated IPv4 addresses to support vulnerability assessment and remediation.
Detects a malformed PHPSESSID Set-Cookie header indicative of CVE-2026-109618, which may result in stale session ID memory disclosure in PHP applications.
Detects HTTP POST requests containing multipart/form-data with PHP_SESSION_UPLOAD_PROGRESS, which is associated with CVE-2026-109618 and CVE-2026-109619 exploitation attempts, tracked via a detection filter.
Detects HTTP requests containing serialized PHP objects in the Cookie header matching patterns associated with Zend Framework or Laminas gadget chains, characteristic of PHP object deserialization exploitation (e.g., PHPGGC style).
Detects HTTP requests targeting Microsoft Exchange servers that combine the autodiscover.json URI with PowerShell endpoint parameters, indicative of ProxyNotShell vulnerabilities exploitation (CVE-2022-41040 and CVE-2022-41082).
Detects an unauthenticated remote code execution attempt against AhsayCBS via the UpdateReceivers.do endpoint using the checkSysPwd parameter, associated with CVE-2026-105133 and CVE-2026-105134.
Detects an exploitation attempt against PoeLLM or LiteLLM MCP test/connection endpoint using a python3 stdio payload that fetches data from port 81.
Detects an unauthenticated remote code execution attempt against AhsayCBS via the UpdateReceivers.do endpoint using the checkSysPwd parameter, associated with CVE-2026-105133 and CVE-2026-105134.
Detects an unauthenticated remote code execution attempt against AhsayCBS via the UpdateReceivers.do endpoint using the checkSysPwd parameter, associated with CVE-2026-105133 and CVE-2026-105134.

Detects an exploitation attempt against PoeLLM or LiteLLM MCP test/connection endpoint using a python3 stdio payload that fetches data from port 81.
Detects an exploitation attempt against PoeLLM or LiteLLM MCP test/connection endpoint using a python3 stdio payload that fetches data from port 81.
This rule detects HTTP requests containing both Content-Length and Transfer-Encoding headers, which is a technique used in HTTP Request Smuggling attacks. This specific signature targets attempts to exploit CVE-2026-88773 in Citrix NetScaler.
Detects exploitation attempts against Microsoft SharePoint leveraging the ToolShell exploit chain, as well as subsequent post-exploitation webshell activity involving anomalous 'layoutNsp.aspx' naming conventions. This covers initial exploitation of vulnerabilities such as CVE-2025-49704 and associated variants, followed by the deployment of webshells associated with the ToolShell campaign.

Detects attempts to exploit CVE-2026-83549 in SonicWall SMA1000 appliances, where an attacker sends a malicious HTTP request to the 'workplace' URI containing shell metacharacters such as ';', '|', '`', or '$(' to execute arbitrary OS commands.
Detects an exploitation attempt against PoeLLM or LiteLLM MCP test/connection endpoint using a python3 stdio payload that fetches data from port 81.
Detects SQL injection exploitation attempts against MOVEit Transfer targeting the CVE-2023-34362 vulnerability, followed by the deployment and subsequent interaction with the 'human2.aspx' webshell associated with Cl0p ransomware mass-exploitation campaigns.
This rule detects HTTP POST requests targeting Adobe Commerce or Magento checkout, customer, or admin endpoints that contain suspicious syntax patterns indicative of Server-Side Template Injection (SSTI). These patterns ({{...}}, {%...%}, ${...}) are common in various template engines and, when injected into application inputs, can lead to Remote Code Execution (RCE) via CVE-2026-75650.
