Re: XSS in Oracle default fcgi-bin/echo

I wrote about a week ago:

Many Oracle web server installations have a  fcgi-bin/echo  script
left over from default demo (google for inurl:fcgi-bin/echo). That
script seems vulnerable to XSS. (PoC exploit and explanation of
impact withheld now.)

I asked security () oracle com and they said that "... this issue has
been resolved in an earlier Critical Patch Update." I looked at some
recent CPU summaries, but did not notice anything relevant: maybe
their reply refers to the old http://www.kb.cert.org/vuls/id/717827 ?

Website owners please remove demo software from production servers,
e.g. as per Oracle recommendation
http://download.oracle.com/docs/cd/B14099_19/core.1012/b13999/checklist.htm#BABIBCIC

Oracle now told me that (they double-checked and)
  The issue ... has been addressed by the fixes released in CPUJan2007.
Could someone verify whether that in fact solves the issue?

Hmm... maybe difficult to verify, since I did not post a PoC test.
Maybe a kind Oracle admin could point me to a patched fcgi-bin/echo?
Funny if any such existed: an admin careful to keep patches up-to-date,
but careless in not following security recommendations to remove...
Maybe, contact me off-list so I can provide PoC?

Cheers, Paul
