PYSEC-2023-179

Vulnerability from pysec - Published: 2023-09-28 05:15 - Updated: 2023-09-28 10:29
VLAI?
Details

This affects versions of the package pydash before 6.0.0. A number of pydash methods such as pydash.objects.invoke() and pydash.collections.invoke_map() accept dotted paths (Deep Path Strings) to target a nested Python object, relative to the original source object. These paths can be used to target internal class attributes and dict items, to retrieve, modify or invoke nested Python objects.

Note:

The pydash.objects.invoke() method is vulnerable to Command Injection when the following prerequisites are satisfied:

1) The source object (argument 1) is not a built-in object such as list/dict (otherwise, the init.globals path is not accessible)

2) The attacker has control over argument 2 (the path string) and argument 3 (the argument to pass to the invoked method)

The pydash.collections.invoke_map() method is also vulnerable, but is harder to exploit as the attacker does not have direct control over the argument to be passed to the invoked function.
