IDOR in Envasadora H2O Eireli Soda Cristal v40.20.4

Successful exploitation allows an authenticated attacker to bypass intended access controls and retrieve sensitive data associated with other users. The primary impact is unauthorized disclosure of data across tenant or user boundaries, with potential privacy, confidentiality, and regulatory consequences depending on the nature of the exposed information.

Restrict access to the application to only necessary users and networks until a fix is applied. Monitor and log requests for abnormal object identifier enumeration or access patterns indicative of IDOR exploitation. Implement compensating controls such as web application firewall rules or API gateway policies to detect and block suspicious parameter tampering where feasible. Conduct an authorization review of endpoints exposing record, account, or document identifiers.

Upgrade to a vendor-fixed version if one is available. The application should enforce server-side authorization checks for every object access, ensuring that referenced resources are validated against the authenticated user's permissions before data is returned. Replace direct object references with indirect, unguessable identifiers where appropriate, but do not rely on identifier complexity alone as a security control. Review all endpoints handling user-supplied object identifiers for similar authorization flaws.
