CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This vulnerability is a path traversal issue in the Ne-Lexa php-zip library up to version 4.0.2. It affects the ZipFile::extractTo function in src/ZipFile.php, where manipulating the entryName argument allows an attacker to access files outside the intended directory. The attack can be executed remotely and the exploit is publicly available.

Impact Analysis

An attacker could read sensitive files, overwrite existing files, or execute arbitrary code on the server by exploiting this path traversal. This may lead to data breaches, system compromise, or unauthorized access to confidential information.

Compliance Impact

This vulnerability could violate GDPR by exposing personal data or HIPAA by leaking protected health information. Non-compliance may result in legal penalties, fines, or reputational damage due to unauthorized data access.

Mitigation Strategies

Immediately update php-zip to the latest version beyond 4.0.2 if available. If no update exists, consider disabling the ZipFile::extractTo function or replacing the component with a secure alternative. Monitor network traffic for unusual path traversal attempts in ZIP file handling.
