Detect Google Chromium V8 Type Confusion Exploitation (CVE-2025-13223) in Sumo Logic CSE
Detects exploitation attempts targeting CVE-2025-13223, a type confusion vulnerability (CWE-843) in Google Chromium's V8 JavaScript engine. This KEV-listed vulnerability allows remote attackers to execute arbitrary code via a crafted HTML page. Exploitation typically involves a malicious web page triggering memory corruption through confused object type handling in V8, leading to sandbox escape or remote code execution within the browser process.

Data Sources
False Positives & Tuning
- Electron applications (VS Code, Slack, Discord) that embed Chromium and spawn shell processes for legitimate operations
- Browser-driven automation or RPA tools running on endpoints
- IT management tools that invoke browser APIs and shell commands as part of normal administration workflows
- Security awareness training platforms that launch browsers and may spawn ancillary processes

Testing Methodology
Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Simulate V8 Sandbox Escape - Chrome Spawning cmd.exe
Expected signal: Sysmon EventID 1 (ProcessCreate) with ParentImage matching chrome.exe and Image matching cmd.exe; DeviceProcessEvents in MDE showing FileName=cmd.exe with InitiatingProcessFileName=chrome.exe
- Test 2Browser Process Network Beacon Simulation Post-Exploitation
Expected signal: Sysmon EventID 3 (NetworkConnect) with Image=powershell.exe, ParentImage=chrome.exe (or powershell spawned in context of test), DestinationIp=192.0.2.1, DestinationPort=4444; DeviceNetworkEvents with InitiatingProcessFileName=powershell.exe
- Test 3Chrome Crash Dump Generation - Exploitation Indicator Simulation
Expected signal: Sysmon EventID 11 (FileCreate) events for each .dmp file creation in the Crashpad reports directory; DeviceFileEvents with FileName ending in .dmp and FolderPath containing Crashpad
- Test 4Linux - Chromium Renderer Child Process Spawn Simulation
Expected signal: Linux audit log (auditd) or Sysdig/Falco events showing bash or sh spawned with ppid matching chromium-browser process; EDR telemetry (CrowdStrike Falcon for Linux, SentinelOne) recording process lineage
