This page is intended to provide assistance and directions to editors of the 2007 Top 10 Vulnerabilities list. The Wiki version is intended to be modified by the OWASP community at large. While it is understood that this means that it will not be scrutinized as intensely as the English PDF version has been (months of review including Beta, RC1, and RC2), the Wiki version is still intended to maintain a high degree of quality. If you intend on making any significant changes, please subscribe to and contact the email list via its home page.

That being said, please help this document grow.

Markup Used

Markup or Style When used
= H1 - Never used in top 10
== H2 - used as main headers within a page. Will be appear in TOC if one is included.
=== H3 - used as second-level headers within a page. Will not appear in TOC by default.
&lt; and &gt; Used instead of < and > when used as strings as compared to HTML tags. Sometimes the Wiki allows < and > to go through without using the escapes but sometimes it does bad things. For example "<b>" '''BOLD''' notbold actually produces "" BOLD notbold. Probably not what you want.
__NOTOC__ Prevents default display of TOC which happens as soon as there is a total of four or more H1 (shouldn't be used) or H2 headers.
__TOC__ Forces creation of a TOC at that point - even if a TOC would otherwise have not been generated.
&ldquo; and &rdquo; Used as “double quote characters” where needed.
&lsquo; and &rsquo; Used as ‘singe quote characters’ where needed.
<code> and </code> Used to dilineate code (fixed-width font, slightly gray background).

Template Pages

Page Link Contents of Page
Template:Top_10_2007:TopTemplate Template to produce the top of the page.
Template:Top_10_2007:BottomTemplate Template to produce the bottom of the page.
Template:PrevLink Template to produce link to previous page in Template:Top_10_2007:TopTemplate and Template:Top_10_2007:BottomTemplate.
Template:MainLink Template to produce link to the Top_10_2007 main page in Template:Top_10_2007:TopTemplate and Template:Top_10_2007:BottomTemplate.
Template:Nothing Template that produces nothing. It is used by Template:Top_10_2007:TopTemplate and Template:Top_10_2007:BottomTemplate to produce nothing. For example, Top 10 2007 has no previous nor main link so the Nothing template is called instead.
Template:FIXUP Template that produces FIXUP notes. The template takes two arguments. The first is a name identifying the user (could be full name, username, initials, it is simply for identification) who added the FIXUP tag. The second is a comment about what needs to be fixed up. For example, {{FIXUP|Neil Smithline|Demo of FIXUP}} produces

FIXUP: {{{1}}}: {{{2}}}
