Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in Asterisk allowing for SQL |
| 19 |
injection, session hijacking and unauthorized usage. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Asterisk is an open source telephony engine and tool kit. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-misc/asterisk < 1.2.27 >= 1.2.27 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Asterisk upstream developers reported multiple vulnerabilities: |
| 38 |
|
| 39 |
* The Call Detail Record Postgres logging engine (cdr_pgsql) does not |
| 40 |
correctly escape the ANI and DNIS arguments before using them in SQL |
| 41 |
statements (CVE-2007-6170). |
| 42 |
|
| 43 |
* When using database-based registrations ("realtime") and host-based |
| 44 |
authentication, Asterisk does not check the IP address when the |
| 45 |
username is correct and there is no password provided |
| 46 |
(CVE-2007-6430). |
| 47 |
|
| 48 |
* The SIP channel driver does not correctly determine if |
| 49 |
authentication is required (CVE-2008-1332). |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
Remote authenticated attackers could send specially crafted data to |
| 55 |
Asterisk to execute arbitrary SQL commands and compromise the |
| 56 |
administrative database. Remote unauthenticated attackers could bypass |
| 57 |
authentication using a valid username to hijack other user's sessions, |
| 58 |
and establish sessions on the SIP channel without authentication. |
| 59 |
|
| 60 |
Workaround |
| 61 |
========== |
| 62 |
|
| 63 |
There is no known workaround at this time. |
| 64 |
|
| 65 |
Resolution |
| 66 |
========== |
| 67 |
|
| 68 |
All Asterisk users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.27" |
| 72 |
|
