CVE-2020-14942Network attack vector

Code execution via unvalidated pickled saved queries

Published Jun 21, 2020 · Updated Aug 4, 2024

Untrusted deserialization in Tendenci 12.0.10 and earlier allows remote authenticated users to execute code through saved helpdesk queries. The ticket_list view base64-decodes SavedSearch.query and passes it to pickle.loads after save_query stores the encoded form value without validation. A valid account with saved-query access is required, and successful exploitation runs attacker-controlled Python in the server process.
