OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the AuthType
is set to anything but Basic
, if the request contains an Authorization: Basic ...
header, the password is not checked. This results in authentication bypass. Any configuration that allows an AuthType
that is not Basic
is affected. Version 2.4.13 fixes the issue.
