Try this (it should be obvious how to modify it):

\documentclass{article}
\makeatletter
\newcommand{\infobox}[1]{%
  \fbox{\vbox{\noindent #1}}\vspace*{\baselineskip}\@afterheading
}
\makeatother
\begin{document}
\section{A new section}
\infobox{A short description\\forced on two lines.}
This is the section text...
\end{document}
