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 command execution.

  "executiveSummary": "This vulnerability involves an Improper Neutralization of Special Elements used in an OS Command (OS Command Injection) within Dell SCG 5.0 Appliance and Application versions. The flaw allows a local, low-privileged attacker to execute arbitrary system commands on the underlying operating system.\nThe vulnerability resides in the way the affected software processes inputs, failing to adequately sanitize data before passing it to system-level commands. This creates a severe security risk as it enables unauthorized code execution with the privileges of the application process.\nAffected products include 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).\nSuccessful exploitation requires local access, allowing an attacker to escalate their impact by interacting with the command shell. The primary risk implication is a total compromise of the appliance's integrity and confidentiality if the application process runs with elevated privileges.",
  "technicalDetails": "The vulnerability is categorized as CWE-78: Improper Neutralization of Special Elements used in an OS Command (OS Command Injection). The root cause is the failure of the application to properly validate or sanitize user-supplied input before incorporating it into a string intended for execution by the underlying OS shell.\nThe attack vector necessitates that an attacker possesses low-privileged local access to the system. By injecting malicious command sequences—often using shell metacharacters such as semicolons, pipes, or backticks—the attacker can manipulate the intended command string to execute secondary, unauthorized commands.\nThe exploitation flow begins when an attacker provides crafted input to a vulnerable component or interface within the SCG Appliance or Application. If the application logic improperly handles this input, it transmits the modified command string to the system shell. Upon reception, the shell executes the primary command followed by the injected payload, effectively extending the command line argument list to include attacker-controlled instructions.\nBecause the application process is responsible for invoking these system calls, the injected payload executes with the same privilege level as the parent application. If the service is running with root or administrative privileges, the attacker achieves full control over the appliance. Even with restricted service accounts, the ability to execute OS commands facilitates internal reconnaissance, persistence, and lateral movement within the network segment where the SCG appliance is deployed.\nAffected versions include Dell SCG 5.0 Appliance versions before 5.36.00.16 and Dell SCG 5.0 Application versions before 5.36.00.00. The lack of neutralization for special characters constitutes a failure in secure coding practices, specifically regarding the interaction between high-level management software and the OS execution layer.\nPost-exploitation impact includes potential data exfiltration, modification of system configurations, denial-of-service by terminating critical processes, or the installation of persistent backdoors to ensure ongoing unauthorized access."
