Description

Dell SmartFabric OS10 Software, versions prior to 10.5.6.14, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Command execution.

  "executiveSummary": "Dell SmartFabric OS10 Software, specifically versions prior to 10.5.6.14, is susceptible to an OS Command Injection vulnerability (CWE-78). This flaw arises from improper neutralization of special elements used in system commands. An attacker with high-level privileges and remote access can exploit this vulnerability to execute arbitrary commands on the underlying operating system. The successful exploitation of this flaw allows a malicious actor to circumvent security boundaries, potentially leading to unauthorized system control, data manipulation, and compromise of network device integrity. Given the elevated privileges required for exploitation, this vulnerability poses a significant risk to the security posture of the network infrastructure. Mitigation involves updating the software to the specified version or later, as the patch addresses the root cause of the improper input validation.",
  "technicalDetails": "The vulnerability resides within the command-line interface or management interface of Dell SmartFabric OS10, where user-supplied input is passed to system-level utilities without sufficient sanitization or validation. This constitutes an OS Command Injection (CWE-78) flaw, which occurs when an application constructs a system command by concatenating insecure user-provided strings with fixed command structures. Because the input is not properly neutralized, an attacker can supply malicious metadata or shell metacharacters to alter the intended command structure, effectively 'breaking out' of the intended application logic and executing arbitrary commands with the privileges of the service account responsible for running the CLI or management shell.\nThe attack flow begins when an attacker, already authenticated with high privileges, interacts with the affected management interface. By injecting specially crafted payloads containing shell operators such as semicolons, pipes, or command substitution characters (e.g., $(command)), the attacker forces the system to interpret these characters as commands to be executed by the host operating system shell. Since the process executing these commands operates with high privileges, the injected commands inherit those permissions, allowing for full system interaction, including modifying configuration files, exfiltrating sensitive data, or establishing a persistent backdoor.\nThe scope of impact is critical, as it bypasses the intended abstraction layer of the OS10 software. Exploitation is remote, relying on network access to the management interface and existing high-level authentication credentials. The vulnerability is present in all versions prior to 10.5.6.14, indicating a systemic issue in input handling routines within the product's codebase. The post-exploitation impact includes complete system compromise, where the attacker can influence the control plane of the network device, manipulate traffic forwarding configurations, or utilize the device as a pivot point for further lateral movement within the production network. The absence of strict input validation mechanisms allows this command concatenation, confirming that the vulnerable component fails to enforce secure coding practices when interfacing with the underlying OS shell."
