Detects attempts to exploit a Rejetto HTTP File Server (HFS) via CVE-2014-6287. The rule looks for specific patterns in the URI query that indicate an attempt to inject commands or save files, which are characteristic of this vulnerability. The presence of '?search=%00{.' combined with keywords like 'powershell', 'cmd.exe', 'cscript', 'wscript', 'python', or paths like 'C:\Users\Public\' suggests an exploitation attempt.
Detects suspicious command execution by child processes of the GoAnywhere Managed File Transfer (MFT) application, which may indicate exploitation such as CVE-2025-10035. This behavior is indicative of post-exploitation activity related to CVE-2025-10035, as observed in campaigns by the threat actor Storm-1175.
Detects potential exploitation of Cisco SNMP vulnerability (CVE-2025-20352) by identifying shell command patterns within SNMP traffic, indicative of remote code execution attempts as seen in Operation Zero Disco.
This analytic is designed to identify attempts to exploit a server-side template injection vulnerability in CrushFTP, designated as CVE-2024-4040. This severe vulnerability enables unauthenticated remote attackers to access and read files beyond the VFS Sandbox, circumvent authentication protocols, and execute arbitrary commands on the affected server. The issue impacts all versions of CrushFTP up to 10.7.1 and 11.1.0 on all supported platforms. It is highly recommended to apply patches immediately to prevent unauthorized access to the system and avoid potential data compromises. The search specifically looks for patterns in the raw log data that match the exploitation attempts, including READ or WRITE actions, and extracts relevant information such as the protocol, session ID, user, IP address, HTTP method, and the URI queried. It then evaluates these logs to confirm traces of exploitation based on the presence of specific keywords and the originating IP address, counting and sorting these events for further analysis.
Detects suspicious file writes to the root directory of web applications, specifically targeting Apache or Tomcat servers. This activity often indicates an attempt to deploy malicious files like web shells or other unauthorized scripts, potentially after exploiting a public-facing application.
This correlation rule identifies multiple risk events associated with the "Living Off The Land" analytic story. It aggregates and correlates events tagged under this story, focusing on systems with a high count of distinct sources (5 or more). The rule aims to detect suspicious behavior involving the use of legitimate tools for malicious purposes, which could lead to code execution, privilege escalation, or persistence within an environment.
Detects the use of argument injection in the Commvault qlogin command, specifically targeting CVE-2025-57791. An attacker can inject the `-localadmin` parameter via the password field to bypass authentication and gain a privileged token.
This detection identifies potential exploitation of a critical SQL injection vulnerability in Ivanti Endpoint Manager (EPM), identified as CVE-2024-29824. The vulnerability, which has a CVSS score of 9.8, allows for remote code execution through the `RecordGoodApp` function in the `PatchBiz.dll` file. An attacker can exploit this vulnerability by manipulating the `goodApp.md5` value in an HTTP POST request to the `/WSStatusEvents/EventHandler.asmx` endpoint, leading to unauthorized command execution on the server. Monitoring for unusual SQL commands and HTTP requests to this endpoint can help identify exploitation attempts. Note that, the detection is focused on the URI path, HTTP method and status code of 200, indicating potential exploitation. To properly identify if this was successful, TLS inspection and additional network traffic analysis is required as the xp_cmdshell comes in via the request body.
The following analytic identifies attempts to exploit Jenkins Arbitrary File Read CVE-2024-23897. It detects HTTP POST requests to Jenkins URLs containing "*/cli?remoting=false*" with a 200 status code. This activity is significant as it indicates potential unauthorized access to sensitive files on the Jenkins server, such as credentials and private keys. If confirmed malicious, this could lead to severe data breaches, unauthorized access, and further exploitation within the environment.
The analytic detects attempts to exploit the Fortinet FortiNAC CVE-2022-39952 vulnerability. It identifies HTTP POST requests to the URI configWizard/keyUpload.jsp with a payload.zip file. This activity indicates an attempt to exploit a known vulnerability, potentially leading to remote code execution. If confirmed malicious, attackers could gain control over the affected system, schedule malicious tasks, and establish persistent access via a remote command and control (C2) server.
This analytic detects potential exploitation of the Ivanti Virtual Traffic Manager (vTM) authentication bypass vulnerability (CVE-2024-7593) to create new administrator accounts. The vulnerability allows unauthenticated remote attackers to bypass authentication on the admin panel and create new admin users. This detection looks for suspicious new account creation events in the Ivanti vTM audit logs that lack expected authentication details, which may indicate exploitation attempts.
The following analytic detects the creation of new ASPX files in the MOVEit Transfer application's "wwwroot" directory. It leverages endpoint data on process and filesystem activity to identify processes responsible for creating these files. This activity is significant as it may indicate exploitation of a critical zero-day vulnerability in MOVEit Transfer, used by threat actors to install malicious ASPX files. If confirmed malicious, this could lead to exfiltration of sensitive data, including user credentials and file metadata, posing a severe risk to the organization's security.
The following analytic detects attempts to exploit the ConnectWise ScreenConnect CVE-2024-1709 vulnerability, which allows attackers to bypass authentication via alternate paths or channels. It leverages Nginx access logs to identify web requests to the SetupWizard.aspx page, indicating potential exploitation. This activity is significant as it can lead to unauthorized administrative access and remote code execution. If confirmed malicious, attackers could create administrative users and gain full control over the affected ScreenConnect instance, posing severe security risks. Immediate remediation by updating to version 23.9.8 or above is recommended.
The following analytic identifies potential exploitation of the WordPress Bricks Builder plugin RCE vulnerability. It detects HTTP POST requests to the URL path "/wp-json/bricks/v1/render_element" with a status code of 200, leveraging the Web datamodel. This activity is significant as it indicates an attempt to exploit CVE-2024-25600, a known vulnerability that allows remote code execution. If confirmed malicious, an attacker could execute arbitrary commands on the target server, leading to potential full system compromise and unauthorized access to sensitive data.
This detection identifies attempts to authenticate with an empty public key fingerprint in Progress MOVEit Transfer, which is a key indicator of potential exploitation of the CVE-2024-5806 vulnerability. Such attempts are characteristic of the authentication bypass technique used in this vulnerability, where attackers try to impersonate valid users without providing proper credentials. While occasional empty key fingerprint authentication attempts might occur due to misconfigurations, a sudden increase or attempts from unexpected sources could signify malicious activity. This analytic helps security teams identify and investigate potential exploitation attempts of the MOVEit Transfer authentication bypass vulnerability.
