| 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. |
