Hello, I'm new to Perl....& this web application built on perl-cgi(~10 yrs old app) Recently the Rational webAppscan that scanned the URL ,reported several(20) cgi modules for Cross-Site Request Forgery (CSRF). I didnt see anything obvious...I was hoping someone could point out the code that is causing the vulnerability Below is the code (both cgi & the template)of one of the module *****************************sched_history.tmpl************************************************************************ 
<TMPL_INCLUDE NAME="./icon_top.tmpl">
<!--webbot bot="Include" endspan i-checksum="28680" -->

<p class="page-header">Distribution Schedule Audit Log</p>
<hr class="header-line">
<br>

<form name=schedhistform method=POST action="/gdr/cgi-bin/user_detail.
+cgi">
<input type=hidden name=user_id value="<tmpl_var name=user_id>">
<input type=hidden name=sched_effective_dt>


<table class="data-table">
<caption class="info-table-caption">Distribution ID: <TMPL_VAR NAME=US
+ER_ID></caption>
<tr class="info-table-header">
  <td>Effective Date</td>
  <td>Status</td>
  <td>Updated By</td>
  <td>Description</td>
</tr>

<TMPL_LOOP NAME=sched_history_list>
<tr class="<tmpl_if name=__ODD__>shaded<tmpl_else>unshaded</tmpl_if>"

  <td><TMPL_VAR NAME=SCHED_UPD_USER_ID></td>
  <td><TMPL_VAR NAME=DESC></td>

</TMPL_LOOP>
