Description Sam Fowler 2018-07-27 01:57:51 UTC
Mailman before version 2.1.28 has a vulnerability in the Utils.py:GetPathPieces() function that allows an attacker to submit URLs with long listnames resulting in arbitrary text to be echoed in "No such list" error responses. This can be used to make a potential victim think the phishing text comes from a trusted site.
