Detects the spawning of suspicious child processes by the Atlassian Confluence server, which may indicate successful exploitation of CVE-2021-26084. The rule specifically looks for the Confluence Java process spawning common command-line utilities and scripting interpreters often used in post-exploitation activities.
Detects successful exploitation attempts of the Microsoft Exchange Server vulnerability CVE-2021-28480. This vulnerability allows for remote code execution. The rule specifically looks for POST requests to '/owa/calendar/a' that result in an HTTP 503 status code, indicating a potential successful exploitation or a server error due to the exploit.
Detects exploitation attempts of the SonicWall SSL/VPN Jarrewrite vulnerability. The rule looks for requests to '/cgi-bin/jarrewrite.sh' combined with specific patterns in the 'cs-user-agent' header that indicate command injection attempts, such as ':;', '() {', or '/bin/bash -c'. This targets a known vulnerability allowing attackers to execute arbitrary commands.
This rule detects various suspicious exceptions within Django web applications. These exceptions, such as 'SuspiciousOperation' and its subclasses (e.g., 'DisallowedHost', 'InvalidSessionKey', 'RequestDataTooBig'), as well as 'PermissionDenied', often indicate attempts to exploit vulnerabilities, bypass security controls, or engage in other malicious activities against the web application. Monitoring these exceptions can help identify potential attacks like web parameter tampering, session hijacking attempts, or unauthorized access attempts.
Detects suspicious VSFTPD error messages that indicate a fatal or suspicious error that could be caused by exploiting attempts. These errors often suggest malformed requests or attempts to trigger vulnerabilities in the VSFTPD service.
Rule to detect the use of the SCX RunAsProvider Invoke_ExecuteShellCommand to execute any UNIX/Linux command using the /bin/sh shell. SCXcore, started as the Microsoft Operations Manager UNIX/Linux Agent, is now used in a host of products including Microsoft Operations Manager, Microsoft Azure, and Microsoft Operations Management Suite. This activity is indicative of the OMIGOD vulnerability exploitation.
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.
Detects exploitation attempts of the Microsoft Exchange vulnerability CVE-2020-0688. This vulnerability allows for remote code execution due to improper validation of cmdlet arguments. The rule specifically looks for GET requests to '/ecp/' or '/owa/' paths containing '__VIEWSTATE=' in the query string, which is indicative of the exploitation attempt.
Detects attempts to exploit CVE-2020-10148, an authentication bypass vulnerability in SolarWinds Orion API. This rule looks for specific URI query patterns associated with the exploit, while excluding legitimate requests.
Detects exploitation attempts targeting Microsoft Exchange servers, specifically those associated with the HAFNIUM group's activity. The rule looks for suspicious POST requests to specific URI paths and user-agent strings that were observed during the HAFNIUM attacks.
This rule detects potential JNDI (Java Naming and Directory Interface) injection exploitation attempts within JVM-based applications. It specifically looks for keywords related to LDAP lookups ('com.sun.jndi.ldap.') and the Log4j JndiManager ('org.apache.logging.log4j.core.net.JndiManager') in application error logs. Such patterns are commonly associated with vulnerabilities like Log4Shell, where attackers inject malicious JNDI lookup strings to achieve remote code execution.
Detects suspicious Ruby on Rails exceptions that could indicate exploitation attempts. These exceptions often occur when an attacker is probing a web application for vulnerabilities or attempting to bypass security controls like CSRF tokens, or sending malformed requests.
Detects suspicious exceptions within the Spring framework that could indicate attempts to exploit vulnerabilities. These exceptions often arise during web application attacks such as CSRF attempts, cookie theft, or other forms of unauthorized access or manipulation.
Detects potential Spring Expression Language (SpEL) Injection exploitation attempts, which can lead to Remote Code Execution (RCE). The rule specifically looks for the 'org.springframework.expression.ExpressionException' keyword in application error logs, indicating that an attempt to evaluate a malicious expression might have occurred or failed.
Detects path traversal exploitation attempts
Detects CVE-2021-22123 exploitation attempt against Fortinet WAFs
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.
Detects potential exploitation attempts of CVE-2022-21587, an arbitrary file upload vulnerability impacting Oracle E-Business Suite (EBS). This vulnerability can lead to unauthenticated remote code execution.
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.
Detects suspicious DNS error messages that indicate a fatal or suspicious error that could be caused by exploiting attempts. Specifically looks for messages related to dropping source port zero packets, denied AXFR requests, and fatal errors causing an exit.
