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 remote access could potentially exploit this vulnerability, leading to command execution.

  "executiveSummary": "Dell Secure Connect Gateway (SCG) 5.0 is susceptible to an OS Command Injection vulnerability arising from improper neutralization of special elements within command strings.\nThe vulnerability allows a remote, low-privileged attacker to execute arbitrary OS commands on the underlying appliance or application, potentially resulting in full system compromise.\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.\nThe risk is critical, as successful exploitation bypasses standard application-layer security controls, granting the adversary the ability to manipulate the host operating system, escalate privileges, or move laterally within the network environment.\nThis flaw underscores the necessity of strict input validation for all user-supplied data that interacts with system-level command execution interfaces.",
  "technicalDetails": "The vulnerability is classified as Improper Neutralization of Special Elements used in an OS Command (CWE-78). It resides in the input handling mechanisms of the Dell SCG 5.0 framework, where user-supplied parameters are passed to system-level shells without sufficient sanitization or validation.\nThe root cause involves the application's failure to properly escape or sanitize metadata and special characters—such as semicolons, ampersands, or backticks—that serve as command delimiters or shell metacharacters. When an application constructs a command string dynamically using unsanitized user input, an attacker can append malicious commands to the original intended operation.\nExploitation is feasible for an authenticated low-privileged user possessing remote access. By supplying a crafted payload containing system commands into the vulnerable input fields, the attacker forces the application to execute the injected code with the privileges of the service account running the SCG process.\nThe attack flow proceeds as follows: 1) The attacker identifies a vulnerable input vector within the SCG web interface or API that interfaces with OS-level functions. 2) The attacker crafts a payload utilizing shell metacharacters to terminate the intended command and inject a secondary malicious command (e.g., /bin/bash or curl-based exfiltration). 3) The backend system interprets the user-supplied string as part of the command execution flow, executing the attacker's payload in the context of the host operating system.\nImpact following successful exploitation is severe. Because the code is executed directly on the appliance's underlying OS, an attacker can achieve persistent access, extract sensitive data, modify configurations, or deploy further malicious payloads. The lack of proper isolation between the application layer and the OS layer ensures that an injection success leads to complete system control. The vulnerability affects the Dell SCG 5.0 Appliance and Application platforms, necessitating immediate remediation to maintain the security posture of the infrastructure."
