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 a Command ('Command Injection') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to script injection.

  "executiveSummary": "This vulnerability is classified as an Improper Neutralization of Special Elements used in a Command, commonly referred to as Command Injection. The flaw exists within 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.\nThe vulnerability allows an unauthenticated, remote attacker to execute arbitrary scripts by injecting malicious commands into the system. This poses a significant security risk, as it bypasses standard authentication mechanisms to achieve unauthorized execution of code within the appliance environment.\nThe primary impact includes potential system compromise, unauthorized data access, and the ability for an attacker to maintain persistence or pivot within the network. Successful exploitation requires no prior authentication, significantly lowering the barrier for entry for malicious actors targeting the affected infrastructure.\nOrganizations relying on these versions are at high risk of remote exploitation and should prioritize updating their software to the remediated versions to neutralize this security threat.",
  "technicalDetails": "The vulnerability originates from a failure to adequately sanitize user-supplied input before passing it to a system-level command interpreter or shell execution function within the Dell SCG 5.0 framework. By failing to neutralize special characters and control sequences, the application permits the injection and subsequent execution of arbitrary commands, facilitating script injection.\nIn a standard attack flow, the attacker identifies an exposed network service or endpoint within the Dell SCG appliance that processes user input. Through this interface, the attacker transmits a specially crafted payload containing command delimiters—such as semicolons, pipes, or backticks—followed by malicious system commands. Because the application logic does not properly validate or escape these inputs, the underlying operating system interprets the injected data as executable instructions.\nThe exploitation process typically follows a structured sequence: 1) Identification of the vulnerable input vector through automated or manual reconnaissance; 2) Crafting a payload designed to interact with the shell environment; 3) Delivering the payload via remote, unauthenticated network requests; 4) Execution of the injected script, which runs with the privileges of the application process.\nThe affected components are the Dell SCG 5.0 Appliance (prior to 5.36.00.16) and Dell SCG 5.0 Application (prior to 5.36.00.00). Since the vulnerability is remotely exploitable without authentication, the attack surface is limited only by network accessibility to the appliance. The successful delivery of the payload results in the arbitrary execution of code, which may lead to the exfiltration of sensitive configuration data, installation of backdoors, or complete operational disruption of the affected appliance. Post-exploitation impact is limited only by the permissions assigned to the affected process, which, in many administrative or diagnostic applications, can provide broad visibility into the underlying host environment.\nThe absence of rigorous input validation and the lack of a secure API design that avoids shell-based command execution are the root causes. Developers must transition to safer, parameterized execution methods that strictly define the allowed command space and eliminate the risk of unintended shell invocation."
