pyLoad has an Arbitrary File Write via Path Traversal in edit_package()
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
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.
Exploitation
An authenticated user with MODIFY permission can bypass the sanitization by submitting a payload such as:
`pack_folder=..././..././..././tmp`
After the single-pass replacement, this becomes:
`../../../tmp`
Because the traversal sequences are not properly validated, the resulting normalized path escapes the intended storage directory and writes files to /tmp or other locations.
