Detects exploitation attempts targeting the F5 BIG-IP vulnerability CVE-2020-5902. The rule looks for specific URI query patterns indicative of directory traversal within the '/tmui/' or '/hsqldb' paths, which are known to be vulnerable.
Detects access patterns indicative of the DEWMODE webshell, which was used in attacks exploiting Accellion FTA. The rule looks for specific query parameters ('?dwn=', '&fn=', '.html?' or '&dwn=', '?fn=', '.html?') within the URI query string, which are characteristic of how this webshell operates.
This rule detects attempts to exploit CVE-2019-3398, a path traversal vulnerability in Confluence. The detection logic specifically looks for HTTP POST requests to '/upload.action' containing the path traversal sequence 'filename=../../../../'. This pattern indicates an attempt to upload a file to an arbitrary location on the server, which is characteristic of the CVE-2019-3398 exploitation.
This rule detects suspicious Windows file path strings (e.g., 'C:/Users', 'C:/Windows', 'C:/Program Files') within the URI query component of web requests. The presence of such strings in a URI could indicate an attempt to exfiltrate data from a Windows system or communicate with a webshell that is attempting to access local files or directories. The rule looks for both standard and URL-encoded variations of these paths.
Detects exploitation attempts against the Oracle WebLogic server vulnerability CVE-2021-2109. The rule specifically looks for GET requests containing 'com.bea.console.handles.JndiBindingHandle', 'ldap://', and 'AdminServer' in the URI query, which are indicators of an attempted JNDI injection via LDAP.
This rule detects a specific HTTP GET request pattern associated with potential exploitation of CVE-2023-36884 by the RomCom threat group. The pattern involves a URI containing '/MSHTML_C7/' and a query parameter 'd' followed by an IPv4 address.
Detects exploitation attempts using the JNDI-Exploit-Kit by looking for specific URI patterns in web server logs. These patterns are indicative of various JNDI injection payloads designed to achieve remote code execution, reverse shells, or memory shell deployments on vulnerable applications like Tomcat, Jetty, Weblogic, JBoss, Websphere, and Spring.
This rule detects a 'Segmentation Fault' error message in Apache error logs, indicating a crashing Apache worker process. This type of event can be caused by software vulnerabilities, misconfigurations, or malicious activity aiming to disrupt service availability.
Detects an authentication bypass vulnerability (CVE-2021-40539) affecting the REST API URLs in Zoho ManageEngine ADSelfService Plus. The rule specifically looks for requests to vulnerable endpoints that could be used to exploit this flaw.
This rule detects potential exploitation attempts targeting the Centos Web Panel (CWP) 7, specifically looking for indicators related to CVE-2022-44877, an unauthenticated remote code execution vulnerability. The detection logic focuses on POST requests to '/login/index.php' containing specific query parameters and keywords often associated with reverse shells or command injection, such as 'login=$(' or base64 encoded 'python' strings.
This rule detects potential exploitation attempts of CVE-2023-23752, an improper access check vulnerability in Joomla's web service endpoints. The detection specifically looks for GET requests to the '/api/index.php/v1/' path with the 'public=true' query parameter, which is indicative of an attempt to bypass access controls.
This rule detects attempts to exploit CVE-2010-5278, a directory traversal vulnerability in MODx Revolution. Specifically, it looks for requests to `/manager/controllers/default/resource/tvs.php` with a `class_key` parameter containing a directory traversal sequence (`../../../../../../../../../../`) followed by `windows/win.ini%00`, indicating an attempt to read the `win.ini` file on a Windows server.
Detects suspicious access to specific URLs associated with the exploitation of the ADSelfService Plus vulnerability CVE-2021-40539. Attackers have been observed targeting these URLs to exploit the vulnerability.
Detects attempts to exploit the VMware Workspace ONE Access Authentication Bypass vulnerability (CVE-2022-31656). This vulnerability allows a malicious actor with network access to the UI to obtain administrative access without authentication by sending a specially crafted URI query.
Detects attempts to exploit an Apache Spark server via CVE-2022-33891, which is a shell command injection vulnerability, by looking for specific patterns in web server query strings.
This rule detects a specific threading-related error message in Apache HTTP Server error logs. The error message indicates an issue with priority changes for pthreads, specifically an assertion failure related to `__pthread_tpp_change_priority`. This could be indicative of an underlying problem with the Apache server's threading model, potentially caused by misconfigurations, incompatible modules, or resource exhaustion. While the rule itself doesn't directly detect an attack, such errors could be exploited or could be a symptom of a system under stress or compromise.
This rule detects successful attempts to exploit the IIS shortname vulnerability, which allows enumeration of folders when IIS uses an old .Net Framework. The detection logic looks for HTTP GET or OPTIONS requests to URIs containing '~1' and ending with 'a.aspx', combined with successful HTTP status codes (200 or 301). This pattern is indicative of a successful fuzzing scan for the IIS shortname vulnerability.
This rule detects attempts to enumerate source code repositories, specifically Git repositories, by looking for '.git/' in the URL of GET requests. This activity often indicates an attacker attempting to discover exposed source code.
Detects exploitation attempts targeting the TerraMaster TOS vulnerability CVE-2020-28188. This rule specifically looks for GET requests to '/include/makecvs.php' with a '?Event=' parameter, combined with common command injection payloads such as 'curl', 'wget', '.py', '.sh', 'chmod', or '_GET' in the URI query.
Detects potential exploitation attempts targeting the Cacti Command Injection vulnerability, CVE-2022-46169. The rule looks for specific patterns in GET requests to '/remote_agent.php' with 'action=polldata' and 'poller_id=' in the query, combined with suspicious command injection payloads like 'base64 -d | /bin/bash', 'whoami', 'powershell', 'cmd', or 'wget'.
Detects attempts to exploit the VMware Workspace ONE Access Admin Remote Code Execution vulnerability (CVE-2022-31659) by monitoring for POST requests to the '/SAAS/jersey/manager/api/migrate/tenant' URI. This URI is associated with the migration API, and suspicious activity here could indicate an attacker attempting to leverage the vulnerability for remote code execution.
