Description

Command injection vulnerabilities in the web-based management interface of HPE Networking Fabric Composer could allow an authenticated remote attacker to perform command injection against the affected system. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.

  "executiveSummary": "A critical command injection vulnerability exists within the web-based management interface of HPE Networking Fabric Composer. This vulnerability allows an authenticated remote attacker to bypass input sanitization controls to execute arbitrary operating system commands with elevated privileges.\nThe flaw resides in the handling of user-supplied data within the management interface, which fails to adequately validate or escape input before passing it to system-level calls. Successful exploitation permits an attacker to perform unauthorized actions at the system level, potentially leading to full compromise of the affected appliance.\nGiven that the vulnerability requires prior authentication, the risk is elevated for environments where administrative credentials may be compromised or accessible to unauthorized personnel. The impact of successful exploitation includes complete loss of confidentiality, integrity, and availability of the networking appliance and potential lateral movement into the managed fabric infrastructure.\nOrganizations using the affected software are advised to restrict management interface access to trusted networks and monitor for suspicious process execution patterns associated with web server child processes.",
  "technicalDetails": "The vulnerability is characterized as an OS Command Injection flaw stemming from the insufficient sanitization of input parameters processed by the web-based management interface of HPE Networking Fabric Composer. The root cause is the improper integration of unsanitized user-controlled input into shell-executable functions or backend system calls within the underlying operating system environment.\nThe attack flow begins with the attacker establishing an authenticated session with the management interface. The attacker then identifies a specific web request—typically associated with configuration management or administrative tasks—that processes user input. By injecting malicious shell metacharacters or command separators (such as ';', '&', or '|'), the attacker breaks out of the intended programmatic context to append arbitrary commands. Because the management application runs with elevated privileges on the underlying operating system, the injected commands are executed with equivalent permissions.\nThe vulnerable component is the web service responsible for handling configuration requests. When the application receives a malicious payload, it fails to perform effective input filtering, allowing the payload to reach the system shell or underlying binary interface. This bypasses security boundaries intended to restrict user operations to the application's predefined functionality.\nUpon successful exploitation, the payload executes within the context of the service account running the web management interface. This effectively grants the attacker control over the appliance's underlying OS. Post-exploitation activities may include the deployment of persistent backdoors, the modification of network routing tables, data exfiltration, or the deployment of additional malicious tools to facilitate lateral movement into the network fabric managed by the composer. The attacker can interact with the system at the level of the root user or equivalent privileged account, depending on the service configuration, allowing for unrestricted system manipulation, including the disabling of security logging or the alteration of management policies."
