Description
pyLoad is a free and open-source download manager written in Python. From version 0.5.0b3.dev13 to 0.5.0b3.dev96, the edit_package() function implements insufficient sanitization for the pack_folder parameter. The current protection relies on a single-pass string replacement of "../", which can be bypassed using crafted recursive traversal sequences. This issue has been patched in version 0.5.0b3.dev97.
Affected products
- pyload: from 0.5.0b3.dev13 before 0.5.0b3.dev97 — fixed in 0.5.0b3.dev97
How to fix
Upgrade to a fixed version: pyload 0.5.0b3.dev97. Check the vendor advisory for mitigations.
