Program flaws - The product scripts have flaws which lead to Warnings.

Vendor:
HM2K

Vendor Status: 
HM 2K from eTicket got the Draft advisory on 21 May 2007 and got extensive support in how to fix the security problems on 23 May 2007 and 28 May 2007.
In HM 2K's own words HM 2K "lost interest" and HM 2K "seriously found it too difficult to orchestrate what you [netVigilance] were asking from me [HM 2K], so I just did what I thought was best.". netVigilance's tests show that version 1.5.5.1 is also vulnerable. There currently is no official fix for this advisory.
 
Workaround:
Disable warning messages: modify in the php.ini file following line: display_errors = Off.

REQUEST:
http://[TARGET]/[PRODUCT FOLDER]/index.php?name[]=1 
OR
http://[TARGET]/[PRODUCT FOLDER]/index.php?email[]=1 
OR
http://[TARGET]/[PRODUCT FOLDER]/index.php?phone[]=1 
OR
http://[TARGET]/[PRODUCT FOLDER]/index.php?subject[]=1 
OR (available for version 1.5.5 and also for new version 1.5.5.1)

Make file (example.html) with the next content:
"


action="http://[TARGET]/[PRODUCT FOLDER]/index.php" method="POST">
" Then load it in any web browser. REPLY: Warning: htmlspecialchars() expects parameter 1 to be string, array given in [DISCLOSED PATH][PRODUCT FOLDER]\inc\open_form.php on line [18 OR 26 OR 31 OR 51 OR 55]
