This analytic identifies unauthenticated access attempts to the System Manager Portal in Ivanti Sentry, exploiting CVE-2023-38035. It detects this activity by monitoring HTTP requests to specific endpoints ("/mics/services/configservice/*", "/mics/services/*", "/mics/services/MICSLogService*") with a status code of 200. This behavior is significant for a SOC as it indicates potential unauthorized access, which could lead to OS command execution as root. If confirmed malicious, this activity could result in significant system compromise and data breaches, especially if port 8443 is exposed to the internet.
The following analytic detects potential exploitation of the Adobe ColdFusion vulnerability, CVE-2023-26360, which allows unauthenticated arbitrary file read. It monitors web requests to the "/cf_scripts/scripts/ajax/ckeditor/*" path using the Web datamodel, focusing on specific ColdFusion paths to differentiate malicious activity from normal traffic. This activity is significant due to the vulnerability's high CVSS score of 9.8, indicating severe risk. If confirmed malicious, it could lead to unauthorized data access, further attacks, or severe operational disruptions, necessitating immediate investigation.
The analytic identifies potential server-side template injection attempts related to CVE-2022-22954. It detects suspicious URL patterns containing "deviceudid" and keywords like "java.lang.ProcessBuilder" or "freemarker.template.utility.ObjectConstructor" using web or proxy logs. This activity may indicate an attempt to exploit a known vulnerability in VMware, potentially leading to remote code execution.
This analytic detects potential exploitation attempts against VMWare vRealize Network Insight, specifically targeting the CVE-2023-20887 vulnerability. It monitors web traffic for HTTP POST requests directed at the vulnerable endpoint "/saas./resttosaasservlet." Identifying this behavior is crucial for a SOC as it indicates an active exploit attempt. If confirmed malicious, the attacker could execute arbitrary code, leading to unauthorized access, data theft, or further network compromise.
Detects suspicious file creations within the Palo Alto Networks PAN-OS' parent telemetry folder, specifically looking for filenames containing patterns indicative of OS command injection attempts related to CVE-2024-3400. These files are processed by the 'dt_curl' script, which can lead to arbitrary command execution if device telemetry is enabled and filenames are crafted to bypass shell-subprocess restrictions.
Detects potential exploitation attempts of CVE-2024-3400, an OS command injection vulnerability in Palo Alto GlobalProtect. The rule looks for suspicious strings indicating directory traversal or command injection within Palo Alto GlobalProtect logs.
This rule detects the usage of cleartext protocols over a network by monitoring firewall logs for allowed connections to specific destination ports commonly associated with unencrypted services. These ports include HTTP (80, 8080), FTP (21), Telnet (23), and various database or application-specific ports (e.g., 1433, 3306, 1521, 27017, 50000, 11211, 15672, 5900-5904). The rule specifically looks for 'forward' or 'accept' actions, or connections not marked as 'blocked', indicating active cleartext communication. The primary goal is to identify potential credential exposure or sensitive data transmission over insecure channels.
Ensure that all account usernames and authentication credentials are transmitted across networks using encrypted channels.
Ensure that an encryption is used for all sensitive information in transit. Ensure that an encrypted channels is used for all administrative account access.
