Detailsinfo

A vulnerability was found in django-crm (affected version not known). It has been rated as problematic. This issue affects some unknown functionality of the file message_previews.py of the component massmail module. The manipulation of the argument subject/content with an unknown input leads to a weak password hash vulnerability. Using CWE to declare the problem leads to CWE-916. The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive. Impacted is confidentiality. The summary by CVE is:

DjangoCRM's massmail module renders user-controlled EmlMessage fields (subject, content) through Django's Template() constructor with no sanitization, in at least three locations: message_previews.py builds an f-string embedding message.subject/message.content directly into a Template() call; email_creators.py passes eml_message.subject directly as a template string to Template(); and helpers.py contains the same f-string interpolation pattern. An authenticated user with mass-mail message edit rights can inject Django template syntax ({{ }} / {% %}) that executes at render time, enabling disclosure of other users' data and password hashes via request context variables, CSRF token forgery, and inclusion of arbitrary registered templates.
