CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This vulnerability affects IBM Aspera High-Speed Transfer Endpoint and Server versions 3.7.4 through 4.4.7 Fix Pack 1. It exists in the asperahttpd component and allows an authenticated user to potentially read arbitrary files from the server's local storage that they should not have access to.

Compliance Impact

This vulnerability allows an authenticated user to potentially access files in the server's local storage that they should not have access to, which could lead to unauthorized disclosure of sensitive information.

Such unauthorized file access may impact compliance with data protection regulations like GDPR and HIPAA, which require strict controls on access to personal and sensitive data to prevent data breaches.

Mitigation Strategies

To mitigate the vulnerability in IBM Aspera High-Speed Transfer Endpoint and Server versions 3.7.4 through 4.4.7 Fix Pack 1, it is recommended to upgrade to a fixed version where the issue is resolved.

Although Resource 1 addresses a related buffer overflow vulnerability fixed in version 4.4.7 Fix Pack 2, it implies that upgrading beyond 4.4.7 Fix Pack 1 is necessary to address vulnerabilities in the asperahttpd component.

Upgrade IBM Aspera High-Speed Transfer Endpoint and Server to version 4.4.7 Fix Pack 2 or later.
Restrict authenticated user access to only necessary files and directories to minimize risk.
Monitor and audit user activities on the server to detect any unauthorized file access attempts.

Impact Analysis

An attacker who is an authenticated user could exploit this vulnerability to access sensitive or confidential files stored on the server without proper authorization. This could lead to unauthorized disclosure of information, potentially compromising data confidentiality.
