Vulnerability from variot - Updated: 2022-05-04 09:35

Plesk is a comprehensive control panel solution for managing sites.

If SHORTNAMES = 1 is enabled for email login in Plesk, QMAIL will accept any base64-encoded username starting with a valid shortname during AUTH LOGIN authentication. This allows an attacker to log in to mail or other services protected by the plesk authentication module and relay spam through the smtp authentication permissions obtained.

You must remove SHORTNAMES = 1 from smtp (s) _psa to fix this problem, just setting it to 0 cannot solve it.
