What was once a world of on-premesis network video recorders (NVRs), local storage arrays, and LAN-based management systems is now a connected environment largely operating in the cloud. The cloud has introduced centralized management dashboards, remote access portals, automated updates, and much more bringing better security and efficiency to these critical systems. Each new feature, however, introduces new realms of risk and exposures. Video surveillance, like other smart internet-of-things devices, brings new complexity that must be managed as attackers probe exposed devices to disrupt business and move deeper onto sensitive networks. As part of our ongoing research into modern cloud-enabled surveillance ecosystems, we turned our attention to a major vendor in the surveillance domain, IDIS. IDIS is a global video surveillance manufacturer headquartered in South Korea. IDIS manufactures an end-to-end solution of surveillance products, including IP cameras, network video recorders (NVRs), and video management software (VMS). In addition to the on-prem devices, IDIS offers a cloud management solution called IDIS Cloud Manager (ICM). Our research uncovered a new vulnerability in the IDIS Cloud Manager (ICM) viewer; an attacker could develop an exploit whereby if a user clicks on an untrusted link, the attack would execute on the machine hosting the ICM Viewer. Clicking on untrusted links is widely recognized as a bad practice, and users are routinely educated to avoid doing so. However, under normal circumstances, even if a victim is tricked into visiting an attacker-controlled website, the attacker is typically limited to executing JavaScript within the context of the victim’s browser, which is heavily sandboxed. This vulnerability, however, allows an attacker to escalate beyond the browser sandbox to achieve code execution on the host, introducing a significant security risk. This renders the vulnerability as a 1-click RCE vulnerability, introducing an interesting attack scenario in which a spear-phishing attack could easily be leveraged into a full compromise of the victim’s computer, giving attackers a leg-in to the victim’s network. If exploited, the vulnerability could allow an attacker to execute arbitrary code within the context of the host machine. IDIS ICM runs on a Windows machine connected to the cloud in order to view live video feeds, recordings, and search images. An attacker would be in control of the host machine and have the ability to execute code, or use that machine as a jumping off point for lateral movement to compromise other endpoints on the network, including other surveillance cameras. IDIS requires users who continue to use the ICM Viewer to [upgrade devices to v1.7.1](https://www.cisa.gov/news-events/ics-advisories/icsa-25-308-05), otherwise they should uninstall it immediately. This blog delves into the implementation of the cloud solution from a client-side perspective. The engineers made an interesting design choice to enhance the user experience, which introduced a surprising attack vector that we will examine to understand how an attacker could exploit it to achieve code execution on the victim's computer. ## IDIS Cloud Manager Architecture IDIS’ cloud consists of the IDIS cloud platform, devices (cameras and NVRs), and the ICM Viewer (desktop and mobile). This blog takes a deeper look into ICM Viewer (Web Client) on the PC. ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlMS5wbmc/image1.png?fm=webp&fit=crop&s=c464c4b242df954198855906642116b8) ** *IDIS documentation explains the IDIS cloud architecture.* The desktop IDIS Web Client consists of two independent components: **ICM Web Portal: **A web-based user interface with an assets dashboard in which a user adds and edits devices for cloud management. ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlNS5qcGc/image5.jpg?fm=webp&fit=crop&s=b4c0acff2e3539ff9f35fe0f2fec9084) ** *The IDIS Cloud Manager web portal dashboard* **ICM Viewer:** A program that is installed on Windows machines only. There are two components to the installation: - WCMViewer.exe (ICM Viewer): A Chromium-based UI that allows a user to perform a live monitoring, video search, and backup. The data presented in the client is delivered from the cloud. The authorization is enforced via a `JWT` token that is received from IDIS Cloud Manager upon a login to the web portal . ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlNC5wbmc/image4.png?fm=webp&fit=crop&s=f5ce970b1fce354e0382634399145dc2) ** *The ICM Viewer user interface.* - CWGService.exe (ICMViewer Launcher): A Windows service that listens on port `localhost:16140` and waits for a command to start the ICM Viewer with appropriate arguments like `JWT` Token, language and more. The command to start the Viewer is done by clicking the “Run Viewer” button on the web portal. ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlOC5wbmc/image8.png?fm=webp&fit=crop&s=2259405676b0506a8fb99948358f0f2c) ** *The CWGService.exe listens on localhost:16140.* ## Connection and Authentication Procedure The following are the steps that are executed when a user logs in to the web portal and runs the ICM Viewer: - User provides the username and password on the web portal - The browser generates an RSA key pair - The browser encrypts the data (username, password, public RSA key) with a constant key and sends it to the server. - Upon successful authentication the server responds with following information: - AES key that will be used for further communication (encrypted with RSA public key) - Encrypted (with AES key from 1.) JWT token that will used for communication between ICM Viewer and the cloud server - Encrypted (with AES key from 1.) seed key; at the time probably not used - Encrypted (with AES key from 1.) information about the logged in account At this point, a user has access to a dashboard. Within the dashboard the user can add, edit, and delete devices for cloud management. Once the assets are added, a user can click the “Run Viewer” button (if the installation does not exist or is outdated, and will be prompted to install the program). When a user clicks on “Run Viewer,” the following procedure starts: - The web client opens WebSocket communication with localhost:16140 - The web client encrypts with a constant key, a message that includes the version of expected CWGService and the version of the expected ICM Viewer - If CWGService responds, that means that the versions are correct and the server can accept commands. - The web client therefore sends a message (encrypted with constant key) with a command to initiate the ICM Viewer ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlMy5wbmc/image3.png?fm=webp&fit=crop&s=b6281574add4cc380ef71e825107238b) ** *The encrypted communication above the ws://localhost:16140.* The following is the decrypted message that is sent via web socket to start the “ICM Viewer”: ``` OEM:1 DATATYPE:2 EXECUTECMD: {     "title": "ICM Viewer",     "url": "icm.idisglobal.com",     "protocol": "https:",     "serverAddress": "https://icm.idisglobal.com",     "xAccessToken": "base64(JWT.Token)",     "viewerMode": "LIVE",     "viewerLanguage": "en-USA",     "viewerHashX86": "B75...7D8",     "viewerHashX64": "748...6E9" } ``` When this message is received by the `CWGService` the following process is executed: `WCMViewer.exe --url="https://icm.idisglobal.com" --token=base64(JWT.Token) --mode=w --language=en-US` At this point the ICM Viewer starts and executes all of its sub-processes: ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlOS5wbmc/image9.png?fm=webp&fit=crop&s=7dbe0010407ca152857129f243d8710c) ** *The process explorer showcases the execution of ICM viewer and its subprocesses* ## [CVE-2025-12556](https://claroty.com/team82/disclosure-dashboard/cve-2025-12556) When `WCMViewer.exe` is launched with several arguments: the URL, token, mode, and language. It appears that the URL and the token are passed through, directly from the message received over the WebSocket without any additional processing. The question arises: Can we inject arguments of our own into the `WCMViewer.exe`? As mentioned earlier, `WCMViewer.exe` is a Chromium-based application. It utilizes the `CEF` library, which allows a Chromium browser to be embedded directly inside an application. This raises an interesting question: Will `WCMViewer.exe` accept additional Chromium command-line flags beyond the intended ? Chromium command-line flags provide a powerful mechanism for altering browser behavior at runtime, allowing developers to tailor functionality without modifying the Chromium application; however, while most flags are benign, a subset can be abused to enable code execution. One such flag is `--utility-cmd-prefix`, which is primarily intended for debugging purposes. For example, passing `--utility-cmd-prefix="strace"` to the Chromium command line causes the browser and its utility subprocesses to be wrapped with strace, enabling detailed runtime tracing. Let’s see whether we can inject an argument into the command line that is executed by `CWGService`. To do so, we need to send an appropriate (crafted to include argument injection) message to the `CWGService`. The following steps are needed: - Encrypt (with constant key) “hello” message and send it to the `CWGService` (via WebSocket) - Receive an acknowledgement from the `CWGService` (no need to decrypt) - Encrypt (with constant key) the command message with the injection and send it to the `CWGService`: Below is our pseudo code of our proof-of-concept exploit. ``` def encrypt(data, key):     ... #Construct the "hello" message hello_message = {     "OEM":"1",     "DATATYPE":"1",     "CWG":"1.4.0.6",     "VIEWER":"1.6.0.10" } #Construct the execution message with argument injection cmd_message = {     "title": "ICM Viewer",     "url": "icm.idisglobal.com",     "protocol": "https:",     "serverAddress": "\" --utility-cmd-prefix=\"notepad",     "xAccessToken": "",     "viewerMode": "SEARCH",     "viewerLanguage": "en-US",     "viewerHashX86": "B75...7D8",     "viewerHashX64": "748...6E9" } #Open the Web Socket ws = websocket.WebSocket() ws.connect("ws://127.0.0.1:16140") #Send the "hello" message - this will start the communiction with CWG service ws.send(encrypt(hello_message, HARD_CODED_KEY)) ws.recv(1024) #Send the execution message - this will inject the argument ws.send(encrypt(cmd_message, HARD_CODED_KEY)) ``` As a result: `CWGService` appends the injected argument to the executed command line: ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlNy5wbmc/image7.png?fm=webp&fit=crop&s=d73d4cf05c37ef2897b0d206f490b5a0) ** *The processes explorer showcasing the executed command line with the injected argument.* `WCMViewer.exe` passes the injected parameter to the CEF library and our code is executed. ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlNi5wbmc/image6.png?fm=webp&fit=crop&s=f600ec3cba7dc3b27ddde20627e5206b) ** *A Process Explorer screenshot demonstrating that notepad.exe was successfully launched, confirming that the injected command-line flag resulted in the execution of the intended process.* An attacker’s objective is to achieve code execution on the victim’s system. Because the `CWGService` listens only on the local interface, an attacker can leverage client-side execution by hosting a web page containing JavaScript that sends a crafted WebSocket message to `localhost:16140`. By tricking the victim into visiting this attacker-controlled page, the JavaScript executes in the victim’s browser context and delivers the malicious message to the local service, resulting in code execution on the victim host. ![](https://claroty.com/img/asset/YXNzZXRzL19pZGlzLXQ4Mi1ibG9nL2ltYWdlMi5wbmc/image2.png?fm=webp&fit=crop&s=ce76ad43b3d9841fd11895e0895ea3e3) ** *Malicious JavaScript code.* Clicking on untrusted links is widely recognized as a bad practice, and users are routinely educated to avoid doing so. However, under normal circumstances, even if a victim is tricked into visiting an attacker-controlled website, the attacker is typically limited to executing JavaScript within the context of the victim’s browser, which is heavily sandboxed. In contrast, this vulnerability allows an attacker to escalate beyond the browser sandbox and achieve code execution on the host itself, introducing a significant security risk. ### Disclosure The vulnerability was disclosed to IDIS and confirmed by the vendor soon after disclosure. CISA issued CVE-2025-12556 with CVSS v4 score of 8.7. All customers are advised to patch their systems. The CISA advisory can be found here. ## Wrapping Up The introduction of a new architecture, or feature requires that every step within the chain be thoroughly checked. Our research and exploit was possible because of the following flaws: - The CWSService does not validate origin (missing CORS policy), thus it is possible to communicate with the WebSocket outside of the idisglobal.com domain - Although the messages are encrypted, the encryption happens with a constant key so an attacker can easily communicate with the socket - The CWGService does not sanitizes the passed arguments - The WCMViewer does not validate the passed arguments whether they are legit before forwarding them to the CEF component. Attackers will always look for attack surfaces introduced by new design changes in a product. We encourage the researchers to look for those exposures as well and disclose the vulnerabilities as soon as they are found. We encourage the users to be in the know of what devices they own, and patch them as soon as possible. ![](https://claroty.com/build/assets/team82-newsletter-bg-BlXIsUMi.jpg) Stay in the know Get the Team82 Newsletter Related Vulnerability Disclosures - [ ##### CVE-2025-12556 CWE-88 IMPROPER NEUTRALIZATION OF ARGUMENT DELIMITERS IN A COMMAND ('ARGUMENT INJECTION'): An argument injection vulnerability exists in the affected product that could allow an attacker to execute arbitrary code within the context of the host machine.
