Argument injection leading to 1-click RCE in IDIS Cloud Manager (ICM) Viewer for Windows
CVE-2025-12556 is an argument injection vulnerability in IDIS Cloud Manager (ICM) Viewer for Windows. The ICM Web Portal (web UI) communicates over a local WebSocket endpoint (ws://localhost:16140) to a Windows service/launcher component (CWGService.exe), which then starts the Chromium/CEF-based viewer (WCMViewer.exe) with command-line arguments (e.g., URL, token, mode, language) derived from the WebSocket message. Because CWGService.exe does not validate the WebSocket origin, uses a constant/hard-coded encryption key for messages, and does not sanitize/validate the parameters before launching WCMViewer.exe (and WCMViewer.exe forwards them to CEF), an attacker can craft a malicious webpage with JavaScript that sends a valid encrypted WebSocket message to localhost:16140 and inject additional Chromium command-line flags (notably --utility-cmd-prefix). This enables escaping the browser sandbox and executing arbitrary code on the host with a single user action (visiting/clicking a link).

Unknown (listed as a trending CVE affecting IDIS IP cameras; no technical details provided in the content).
Remote code execution in the Windows-based IDIS Cloud Manager (ICM) Viewer via a local WebSocket-exposed service (CWGService.exe on port 16140) that fails to validate origin/sanitize inputs, enabling injection of Chromium Embedded Framework command-line flags (e.g., --utility-cmd-prefix) to execute arbitrary commands when a user visits a malicious webpage/clicks a link.
A 1-click remote code execution vulnerability in the IDIS Cloud Manager (ICM) Viewer Windows client chain: a local WebSocket service (CWGService.exe) accepts attacker-originated requests (no origin validation), uses a constant encryption key, and fails to sanitize parameters, allowing command-line/Chromium-flag injection into WCMViewer.exe (CEF/Chromium) and resulting in arbitrary code execution on the host.
A critical injection flaw in Idis ICM Viewer (a Chromium-based web client) where unsanitized inputs/arguments are passed to the Chromium Embedded Framework, enabling abuse of Chromium command-line flags to escape the browser sandbox and achieve arbitrary code execution on the local host (one-click via malicious link).
