| Description:
|
- While editing a template we have total access to the User and UserModel classes via $user
- One of the UserModel methods is called setUserId
- If we call setUserId and pass "system" as parameter we get access to the system user role
- To exploit this flaw we need a user with the following permissions/role:
- Active; Back-end User
- Back-end Users need the following permissions:
- View: Sites, Pages, Templates
- Edit: Templates
|
| Mitigation:
|
- Limit Access to Template Screen to Administrative Users
- Upgrade to fix version
