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 exploitation attempts targeting CVE-2020-0688, a remote code execution vulnerability in Microsoft Exchange Server. The rule specifically looks for requests to '/ecp/default.aspx' containing '__VIEWSTATEGENERATOR=' and '__VIEWSTATE=' in the query string, which are indicators of the exploit.
This rule detects exploitation attempts using the Pulse Connect Secure (PCS) vulnerability CVE-2021-22893. The detection logic looks for specific URI query patterns commonly associated with this exploit.
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 exploitation attempts of Sitecore Experience Platform Pre-Auth RCE CVE-2021-42237. This vulnerability allows for remote code execution without authentication. The rule specifically looks for POST requests to the '/sitecore/shell/ClientBin/Reporting/Report.ashx' endpoint that result in a 200 HTTP status code, indicating a successful interaction with the vulnerable component.
Detects URL patterns indicative of ProxyShell exploitation attempts against Microsoft Exchange servers. The rule looks for specific URI query strings and HTTP status codes (401) that are characteristic of both failed and successful exploitation attempts.
Detects URL patterns and status codes that indicate a successful ProxyShell exploitation attack against Microsoft Exchange servers. The rule looks for requests to '/autodiscover.json' combined with specific URI paths like '/powershell', '/mapi/nspi', or '/EWS', and successful HTTP status codes (200 or 301).
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 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 the exploitation of the Microsoft Exchange ProxyToken vulnerability (CVE-2021-33766), which is an authentication bypass. The rule looks for specific URI query patterns and HTTP POST methods combined with a 500 HTTP status code, indicating a potential exploitation attempt against the Exchange Control Panel (ECP) or related services.
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'.
This rule detects HTTP PUT requests where the User-Agent header contains 'WebDAV' and the destination IP address is not a private or loopback address. This activity could indicate an attempt to exfiltrate data to an external WebDAV share.
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.
