This analytic detects exploitation activity of CVE-2025-5777 using Cisco Secure Firewall Intrusion Events. It leverages Cisco Secure Firewall Threat Defense IntrusionEvent logs to identify cases where Snort signature 65118 (Citrix NetScaler memory overread attempt) is triggered. If confirmed malicious, this behavior is highly indicative of a potential exploitation of CVE-2025-5777.
This detection identifies potential exploitation attempts of CVE-2025-5777 (CitrixBleed 2), a memory disclosure vulnerability in Citrix NetScaler ADC and Gateway. The vulnerability is triggered by sending POST requests with incomplete form data to the /p/u/doAuthentication.do endpoint, causing the device to leak memory contents including session tokens and authentication materials. This search looks for POST requests to the vulnerable endpoint that may indicate scanning or exploitation attempts.
This rule detects attempts at Local File Inclusion (LFI) or Remote File Inclusion (RFI) vulnerabilities by analyzing web server logs for specific patterns in the request URI. It looks for directory traversal sequences ('../'), attempts to access common sensitive files like '/etc/passwd', or patterns indicating file inclusion via HTTP or file:// protocols.
Detects HTTP POST requests containing suspicious parameters or headers used by GoldMelody's in-memory IIS modules. Attackers leverage ASP.NET ViewState deserialization to execute payloads in memory, often passing commands and data via non-standard HTTP parameters and headers within POST requests.
Detects a sequence of events indicative of a new device being registered using a refresh token, a TTP associated with the ROADtools framework following an OAuth phishing attack. This sequence involves the Device Registration Service adding a device with a specific hardcoded OS version, followed by user and owner assignments, all within a short timeframe and sharing the same correlation ID.
Detects suspicious script download attempts initiated by a Java process, indicative of potential JDWP exploitation leading to Remote Code Execution (RCE). Attackers often leverage exposed JDWP interfaces to execute commands like downloading and running malicious scripts.
Detects suspicious process executions where Sysmon itself is the parent of a newly created process. This behavior can indicate an exploitation attempt, such as the one described in CVE-2022-41120, where an attacker might leverage a vulnerability in Sysmon to execute arbitrary code with elevated privileges. The rule filters out legitimate Sysmon processes and known system processes that might legitimately be children of Sysmon.
Detects the use of known malicious PowerShell commandlets often associated with exploitation frameworks, red-teaming tools, and malware. This rule identifies a wide range of offensive PowerShell functions used for reconnaissance, credential dumping, privilege escalation, persistence, and data exfiltration.
