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 |
|

------------------------------------------------------------------- |

Package / Vulnerable / Unaffected |

|
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 |
