Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes, where the product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified. In Camaleon cms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A Privilege Escalation through a Mass Assignment exists in Camaleon CMS When a user wishes to change his password, the 'updated_ajax' method of the UsersController is called. The vulnerability stems from the use of the dangerous permit! method, which allows all parameters to pass through without any filtering.
