DescriptionCVE.org

Insecure Permissions vulnerability in the Local Storage in Alteryx Server 2023.1.1.460 allows remote attackers to obtain valid user session tokens from localStorage, leading to account takeover

Executive ViewAI

Why It Matters

Alteryx Server 2023.1.1.460 contains a critical vulnerability that allows attackers to steal user session tokens from browser storage, potentially enabling unauthorized access to user accounts and sensitive data. Organizations running this version face immediate risk of account takeover and data breach, particularly if Alteryx is used to access or process confidential business analytics.

Business Impact: Severe

Compensating Controls

Restrict Alteryx Server access via network segmentation and IP whitelisting; disable remote access until patch is available; implement Web Application Firewall (WAF) rules to block suspicious localStorage access patterns; enforce multi-factor authentication (MFA) for all Alteryx user accounts; increase session monitoring and implement automatic session timeout policies; disable browser caching of sensitive data through response headers; consider disabling Alteryx Server until patch availability is confirmed if deployed in high-risk environments.
