Description

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to script injection.

  "executiveSummary": "Dell Secure Connect Gateway (SCG) 5.0 Appliance and Application versions are affected by an OS Command Injection vulnerability. This vulnerability is classified as an Improper Neutralization of Special Elements used in an OS Command. The security flaw exists due to inadequate sanitization of user-supplied input, which allows an attacker with low-privileged local access to execute arbitrary commands on the underlying operating system. The successful exploitation of this vulnerability could lead to unauthorized script execution, potentially compromising the integrity and confidentiality of the affected appliance. This vulnerability poses a significant risk to the security posture of the infrastructure, as it enables an attacker to move beyond the application layer and interact directly with the OS environment. While the exploit requires local access, the potential for escalation makes this a critical concern for organizations relying on Dell SCG for secure connectivity and management.",
  "technicalDetails": "The vulnerability resides in the input processing mechanisms of Dell SCG 5.0 Appliance (versions prior to 5.36.00.16) and Dell SCG 5.0 Application (versions prior to 5.36.00.00). The core issue is an Improper Neutralization of Special Elements used in an OS Command, commonly referred to as OS Command Injection. This flaw manifests when the application interfaces with the underlying host OS to execute system-level tasks or scripts without properly validating or escaping user-provided arguments.\nThe exploitation process initiates when an attacker with low-privileged local access interacts with an exposed application function that fails to sanitize inputs before passing them to an OS shell or command-line execution utility. By injecting malicious shell metacharacters (e.g., ;, |, &, or $()) into the vulnerable parameter, the attacker can break out of the intended command context.\nThe attack flow proceeds as follows: First, the attacker identifies a component within the SCG environment that performs operations via system calls. Second, the attacker crafts a payload that embeds arbitrary operating system commands alongside legitimate input. Third, when the application processes this input, the vulnerable code executes the combined command string with the privileges of the application process. Because the application often runs with elevated permissions to facilitate gateway functions, the injected commands are executed in a context that may allow for system reconfiguration, credential theft, or further lateral movement within the appliance.\nThe impact is significant: while the primary description mentions script injection, the underlying OS Command Injection capability allows for the execution of arbitrary code, which can facilitate unauthorized file access, process manipulation, or the establishment of a persistent backdoor. Since the vulnerability requires local access, it is particularly dangerous in environments where multiple users share access to the same management host or where an attacker has previously gained low-level access through other vectors. The absence of strict input validation within the specific component allows the OS to interpret attacker-controlled strings as legitimate directives, bypassing the intended security boundaries of the appliance architecture."
