Description

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.

  "executiveSummary": "ICEcoder version 8.1 suffers from an unauthenticated remote code execution vulnerability that enables unauthenticated remote attackers to execute arbitrary operating system commands with the privileges of the underlying web-server user. This critical security flaw exposes affected systems to complete compromise, allowing malicious actors to interact with the host system, manipulate files, and potentially pivot deeper into the network infrastructure. The vulnerability resides in the terminal component of the application, where multiple security controls—specifically authentication checks and Cross-Site Request Forgery (CSRF) validation—can be systematically bypassed. To successfully exploit this flaw, an attacker requires network access to the target application and must dispatch a maliciously crafted HTTP POST request containing specific parameters to satisfy the weak validation logic. No prior authentication, user interaction, or valid session tokens are required, lowering the barrier to exploitation. The risk implication is severe, as successful exploitation yields full system access and control over the web application environment. Remediation requires restricting network exposure, applying official vendor patches if available, or implementing strict access controls at the network and web-server layers to block unauthorized access to sensitive endpoints.",
  "technicalDetails": "The vulnerability stems from flawed security controls within the terminal endpoint of ICEcoder 8.1, allowing unauthenticated remote code execution via a chained sequence of logic bypasses. The root cause involves insufficient authentication enforcement, weak CSRF validation mechanisms, and the direct, unsanitized passing of user-supplied input into dangerous sink functions.\nExploitation occurs when an unauthenticated attacker transmits a single crafted HTTP POST request targeting the terminal endpoint. The attack flow relies on three distinct steps executed within the same request. First, the attacker provides a password parameter designed to bypass the application's authentication checks. Second, the attacker includes a non-empty csrf parameter to successfully bypass the internal CSRF validation routines. Third, the attacker supplies an arbitrary command string appended within the request parameters.\nOnce the preliminary authentication and validation checks are deceptively satisfied, the vulnerable component processes the request by passing the unsanitized command string directly into the proc_open() function. Because the application fails to perform input sanitization, validation, or command filtering, the operating system executes the supplied command payload directly in the context of the web-server user.\nThe affected component is the terminal endpoint of ICEcoder version 8.1. The vulnerability is accessible over the network without requiring any authentication credentials or elevated privileges. The payload behavior results in direct OS command execution, granting the attacker the ability to execute arbitrary commands, read and write sensitive data, and achieve full post-exploitation compromise of the host environment."
