Description

A vulnerability in the affected interface of HPE Networking Fabric Composer allows an attacker with administrative privileges to access sensitive information in a cleartext format. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further access to network services supported by HPE Networking Fabric Composer.

  "executiveSummary": "HPE Networking Fabric Composer contains a critical information disclosure vulnerability within its administrative interface.\nThe vulnerability allows an authenticated attacker possessing administrative privileges to access sensitive data in cleartext format.\nThis flaw stems from improper handling of sensitive information within the application's interface layer, potentially exposing credentials, configuration tokens, or network metadata.\nThe impact of a successful exploitation is significant, as the retrieved cleartext data can be leveraged to facilitate lateral movement, privilege escalation, or unauthorized access to integrated network services managed by the Fabric Composer.\nThe vulnerability requires prior authentication, specifically at the administrative privilege level, limiting the initial attack vector to malicious insiders or compromised administrative accounts.\nGiven the scope of the exposure, the risk is classified as high, necessitating immediate oversight of administrative access and session integrity.",
  "technicalDetails": "The vulnerability resides within the interface layer of the HPE Networking Fabric Composer platform, where sensitive data objects are processed and rendered for administrative consumption.\nThe root cause is identified as an insecure storage or transmission mechanism that fails to mask or encrypt sensitive information before it is presented through the administrative interface.\nAttackers with existing administrative privileges can exploit this by interacting with specific, yet susceptible, interface endpoints that return data objects containing secrets in plaintext.\nThe attack flow commences with the attacker establishing an authenticated session with the target application, successfully bypassing authentication controls by virtue of their administrative status.\nOnce authenticated, the attacker navigates to the affected administrative interface component. By manipulating session requests or targeting specific API endpoints associated with the vulnerable interface, the attacker forces the system to return sensitive information that is intended to be protected or obfuscated.\nBecause the application transmits or stores this sensitive content in cleartext, the interface renders the data directly to the attacker’s browser or API client without secondary validation or masking protocols.\nThis behavior facilitates the exfiltration of credentials, API keys, or configuration parameters essential for the management of the network fabric.\nPost-exploitation, the impact is severe; the attacker can utilize the harvested information to gain unauthorized access to underlying network services, inter-service authentication tokens, or external management interfaces that rely on the compromised data.\nThe vulnerability reflects a failure in the principle of least privilege regarding data display and potential exposure through insecure logging or memory management within the application's backend processing for the administrative console.\nThe exploitation does not necessarily require the deployment of custom malware; rather, it relies on standard administrative interaction with the compromised component to illicitly retrieve the sensitive data payload."
