Description

Improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in CONPROSYS M2M Gateway Series and CONPROSYS M2M Controller Series. If this vulnerability is exploited, an arbitrary OS command may be executed by an attacker who can log in to the product.

  "executiveSummary": "The CONPROSYS M2M Gateway Series and CONPROSYS M2M Controller Series are susceptible to an OS command injection vulnerability, classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command.\nThis vulnerability allows an authenticated attacker to execute arbitrary OS-level commands on the underlying host operating system.\nThe impact of a successful exploitation is critical, as it grants the attacker unauthorized command execution capabilities, potentially leading to full system compromise, loss of confidentiality, integrity, and availability of the device.\nThe primary exploitation requirement is that the attacker must possess valid login credentials to the product.\nGiven the nature of M2M gateways and controllers, such a compromise could facilitate lateral movement into connected industrial or operational technology (OT) networks.\nThe flaw originates from insufficient sanitization of user-supplied input before it is passed to a system shell or command-line interpreter.",
  "technicalDetails": "The vulnerability resides in the input processing logic of the CONPROSYS M2M Gateway Series and CONPROSYS M2M Controller Series. The root cause is the failure to properly neutralize or sanitize special shell metacharacters (e.g., semicolons, backticks, pipes, or ampersands) within input fields processed by the system's administrative or management interfaces.\nWhen the application constructs system calls, it improperly concatenates unsanitized user input into an OS command string. This behavior allows an attacker to inject shell commands that are interpreted and executed by the operating system with the privileges of the application process.\nExploitation involves the following flow: 1. Authentication: The attacker authenticates to the device management interface using valid credentials. 2. Injection: The attacker identifies an input parameter—typically within configuration settings, network diagnostic tools, or system maintenance utilities—that is used to build a back-end command. 3. Manipulation: The attacker supplies a payload containing shell command separators followed by malicious commands (e.g., '; id' or '|| /bin/sh'). 4. Execution: The application passes the modified string to the system shell (e.g., sh, bash, or system() call). The shell interprets the metacharacters, effectively terminating the intended command and initiating the attacker's injected command.\nBecause the vulnerability occurs post-authentication, it constitutes a privilege escalation or abuse of existing access rights. If the application process runs with elevated privileges (e.g., root or a system-level service account), the injected commands inherit these permissions, enabling the attacker to perform unauthorized file system modifications, install backdoors, exfiltrate sensitive configuration data, or disrupt device operations.\nThe attack is highly effective because it bypasses application-level security controls by operating directly at the OS layer. Once command execution is achieved, an attacker can maintain persistence, probe the internal network, or utilize the gateway as a pivot point to attack secondary downstream industrial controllers, significantly broadening the attack surface of the industrial environment."
