OpenMage Magento-LTS Weak Password Reset Token Generation

Publication date: 2026-11-13

Last updated on: 2026-11-13

Assigner: VulnCheck

Description
OpenMage magento-lts before 20.18.2 and 21.0.0-beta pre-releases before 21.0.0-beta3 generate customer email-confirmation keys with md5(uniqid()) and customer and administrator password-reset tokens with the non-cryptographic uniqHash(). Unauthenticated attackers can brute-force the roughly 20-bit confirmation key via the unrate-limited confirmAction endpoint to log in as pending customers, or predict administrator reset tokens after recovering generator state.

Executive Summary

This vulnerability affects OpenMage Magento-LTS versions before 20.18.2 and 21.0.0-beta pre-releases before 21.0.0-beta3. It involves weak generation of email-confirmation keys using md5(uniqid()) and password-reset tokens using the non-cryptographic uniqHash(). Attackers can brute-force these tokens due to limited entropy, allowing unauthorized access to pending customer accounts or predicting administrator reset tokens.

Impact Analysis

Unauthenticated attackers can exploit this to log in as pending customers by brute-forcing confirmation keys via the unrate-limited confirmAction endpoint. They may also predict administrator password-reset tokens after recovering the generator state, potentially gaining administrative access to the system.

Compliance Impact

This vulnerability could lead to unauthorized access to customer data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Failure to address it may result in non-compliance, legal penalties, and reputational damage.

Mitigation Strategies

Upgrade OpenMage magento-lts to version 20.18.2 or later, or 21.0.0-beta3 or later for beta releases. This addresses the weak key generation methods used in email confirmation and password reset tokens.
