CVE-2026-63722 in ICEcoder
Summary
by MITRE • 08/19/2026
ICEcoder 8.1 contains an unauthenticated remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary OS commands by chaining an authentication bypass, CSRF validation bypass, and unsanitized command execution. Attackers can send a single HTTP POST request to the terminal endpoint with a password parameter to bypass authentication, a non-empty csrf parameter to skip CSRF validation, and an arbitrary command string passed directly to proc_open() to achieve remote code execution as the web-server user.

ICEcoder version 8.1 is susceptible to a critical unauthenticated remote code execution vulnerability that stems from multiple interconnected security failures within its administrative interface. The core of this issue lies in the terminal endpoint, which serves as an entry point for executing system commands through the web application. This component fails to implement adequate access controls and input validation mechanisms, allowing malicious actors to bypass standard authentication protocols and execute arbitrary operating system commands with the privileges of the underlying web server process.
The exploitation chain begins with a successful authentication bypass. By sending a specific HTTP POST request to the terminal endpoint containing a password parameter, an attacker can circumvent the intended login requirements. This flaw indicates that the application does not properly validate session tokens or credentials before granting access to sensitive administrative functions. Following this initial breach, the vulnerability extends into cross-site request forgery protections. The system fails to enforce strict CSRF validation when a non-empty csrf parameter is present in the request payload. This oversight allows attackers to bypass security measures designed to prevent unauthorized state-changing requests from being executed on behalf of authenticated users or privileged contexts.
Once authentication and CSRF checks are circumvented, the final stage involves unsanitized command execution. The application directly passes user-supplied input into a proc_open() function without performing any sanitization or validation. This allows an attacker to inject arbitrary operating system commands that are then executed by the web server process. Because proc_open() provides access to low-level shell operations, this flaw results in full remote code execution capabilities rather than limited script injection.
The operational impact of this vulnerability is severe due to its unauthenticated nature and high privilege level. Attackers do not need valid credentials or user interaction to exploit this flaw, making it easily exploitable by automated scanning tools and widespread internet-based attacks. Successful exploitation grants the attacker complete control over the server environment running ICEcoder. This includes the ability to read sensitive configuration files, exfiltrate database contents, install backdoors, pivot into internal networks, and potentially compromise other systems connected to the same infrastructure. The risk is amplified by the fact that web servers often run with elevated privileges relative to standard user accounts, increasing the blast radius of any successful exploitation attempt.
Mitigation strategies should focus on immediate patching and defensive configuration changes. Administrators must upgrade ICEcoder to a version where these vulnerabilities have been addressed by the developers. Until an official fix is available or deployed, it is critical to restrict access to the terminal endpoint using network-level controls such as firewall rules that limit connectivity to trusted IP addresses only. Additionally, implementing Web Application Firewall (WAF) signatures can help detect and block attempts to exploit this specific attack vector by identifying suspicious patterns in POST requests targeting the terminal interface. Regular security audits and code reviews are recommended to identify similar flaws where user input is passed directly into system commands without proper sanitization or validation against industry standards such as CWE-78 for OS Command Injection and CWE-200 for Information Exposure.
