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.

Weakness

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.

Extended Description

If the object contains attributes that were only intended for internal use, then their unexpected modification could lead to a vulnerability. This weakness is sometimes known by the language-specific mechanisms that make it possible, such as mass assignment, autobinding, or object injection.

Potential Mitigations

  • If available, use features of the language or framework that allow specification of allowlists of attributes or fields that are allowed to be modified. If possible, prefer allowlists over denylists.
  • For applications written with Ruby on Rails, use the attr_accessible (allowlist) or attr_protected (denylist) macros in each class that may be used in mass assignment.
