CVE-2007-1558
The APOP protocol allows remote attackers to guess the first 3 characters of a password via man-in-the-middle (MITM) attacks that use crafted message IDs and MD5 collisions.
Does this matter?
Lower severity and a low EPSS score (2.42%). Track it; it rarely justifies an emergency change on its own.
