AI-Generated

An interface that allows authenticated users to upload files is vulnerable due to improper validation of extracted file paths, enabling attackers to manipulate archive contents. This flaw can lead to arbitrary file writes, potentially allowing attackers to inject malicious data or alter application configurations with the privileges of the extraction process. Organizations utilizing this interface should prioritize remediation to mitigate the risk of data integrity breaches and unauthorized access.

Original NVD Description

An interface that accepts file uploads from authenticated users extracts the contents of uploaded archives without validating that extracted file paths remain within the intended destination directory. This allows an authenticated attacker to craft an archive whose entries traverse outside the destination directory, causing the extraction process to write files to arbitrary locations with the privileges of that process. This could allow an attacker to inject fabricated records into the system's stored data or tamper with application configuration.
