Description

Post-authentication Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) which in specific conditions could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution.

  "executiveSummary": "A critical OS command injection vulnerability has been identified within the SMA1000 Appliance Management Console (AMC).\nThis vulnerability is classified as CWE-78: Improper Neutralization of Special Elements used in an OS Command.\nThe flaw allows a remote authenticated attacker with administrative privileges to execute arbitrary OS commands on the underlying appliance.\nSuccessful exploitation facilitates remote code execution (RCE), granting the attacker full control over the management console environment.\nThe primary risk implication is a total compromise of the appliance's security posture, potentially leading to unauthorized data exfiltration, system manipulation, or lateral movement within the network infrastructure.\nExploitation requires the attacker to hold valid administrative authentication to the AMC interface prior to attempting the injection, limiting the threat surface to compromised or malicious internal administrative sessions.",
  "technicalDetails": "The vulnerability resides within the SMA1000 Appliance Management Console (AMC), specifically in the handling of user-supplied input parameters that are passed to system-level calls without adequate neutralization or sanitization.\nThe root cause is an improper neutralization of special elements used in OS commands (CWE-78), where the application fails to distinguish between legitimate administrative configuration data and malicious command-line sequences.\nAn authenticated administrator can interact with specific management functions where input fields, intended for configuration settings, are processed by the underlying operating system shell. By injecting shell metacharacters such as backticks, semicolons, or pipe operators, an attacker can append unauthorized commands to the intended system operation.\nThe attack flow follows a structured sequence: First, the attacker establishes an authenticated session with administrative privileges in the SMA1000 AMC. Second, the attacker identifies a vulnerable interface or endpoint within the AMC that interacts with the OS. Third, the attacker inputs a crafted payload containing malicious OS commands. Fourth, the AMC backend inadvertently executes these commands with the privileges of the management process, which typically operates at a high level of system authority.\nBecause the execution context occurs with elevated administrative privileges, the attacker can achieve persistent access, modify system files, install rootkits, or deploy reverse shells to maintain long-term control over the SMA1000 appliance.\nThe vulnerability demonstrates a failure in secure input validation and the use of dangerous APIs that permit the direct execution of shell commands. Without strict allow-listing of input or the use of parameterized execution APIs, the system remains susceptible to command substitution techniques.\nThis vulnerability is highly severe because it bypasses standard administrative controls, allowing an authenticated administrator to operate outside the intended scope of the AMC application logic. The impact is absolute, as arbitrary OS command execution at the administrator level provides the attacker with sufficient capabilities to disable security monitoring, pivot to other segments of the internal network, or permanently sabotage the device's functionality."
