   |      CVE Name      | CVE-2007-5488                                     |
   +------------------------------------------------------------------------+

   +------------------------------------------------------------------------+
   | Description | The source and destination numbers for a given call are  |
   |             | not correctly escaped by the cdr_addon_mysql module when |
   |             | inserting a record. Therefore, a carefully crafted       |
   |             | destination number sent to an Asterisk system running    |
   |             | cdr_addon_mysql could escape out of a SQL data field and |
   |             | create another query. This vulnerability is made all the |
   |             | more severe if a user were using realtime data, since    |
   |             | the data may exist in the same database as the inserted  |
   |             | call detail record, thus creating all sorts of possible  |
   |             | data corruption and invalidation issues.                 |
   +------------------------------------------------------------------------+

   +------------------------------------------------------------------------+
   | Resolution | The Asterisk-addons package is not distributed with       |
   |            | Asterisk, nor is it installed by default. The module may  |
   |            | be either disabled or upgraded to fix this issue.         |
