Sql injection bugs in Virtuemart and Letterman

["Omid" <omid () hackers ir>]

Hi,

These bugs were published in full-disclosure about 2 weeks ago (CVE :
CVE-2006-6945, CVE-2007-0376 and CVE-2007-0382) .

One sql injection and one XSS bugs exist in Virtuemart 1.0.7 . These can be
exploitable and are not described here . Two new versions have been released
in a short time .

Also 3 sql injection bugs exist in Letterman 1.2.3 (and maybe other versions):

The 'id' parameter in "lm_sendMail()" function is not checked properly
before be used in the sql query :

File components/com_letterman/letterman.class.php, Line 251 :
**      $id  = mosGetParam( $_POST, "id", '' );

File components/com_letterman/letterman.class.php, Line 452 :
**      $database->setQuery( "UPDATE `#__letterman` SET send=NOW() WHERE id=$id" );
::      $database->query();

Other bugs are in "saveNewsletter()" and "cancelNewsletter()" functions .
Again, the 'id' parameter is used without checking . This doesnt work in
Joomla 1.0.12 .
