Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
AWStats contains a bug in the sanitization of the input parameters |
| 19 |
which can lead to the remote execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
AWStats is an advanced log file analyzer and statistics generator. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-www/awstats < 6.5-r1 >= 6.5-r1 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Hendrik Weimer has found that if updating the statistics via the web |
| 38 |
frontend is enabled, it is possible to inject arbitrary code via a pipe |
| 39 |
character in the "migrate" parameter. Additionally, r0t has discovered |
| 40 |
that AWStats fails to properly sanitize user-supplied input in |
| 41 |
awstats.pl. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker can execute arbitrary code on the server in the |
| 47 |
context of the application running the AWStats CGI script if updating |
| 48 |
of the statistics via web frontend is allowed. Nonetheless, all |
| 49 |
configurations are affected by a cross-site scripting vulnerability in |
| 50 |
awstats.pl, allowing a remote attacker to execute arbitrary scripts |
| 51 |
running in the context of the victim's browser. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
Disable statistics updates using the web frontend to avoid code |
| 57 |
injection. However, there is no known workaround at this time |
| 58 |
concerning the cross-site scripting vulnerability. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All AWStats users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=net-www/awstats-6.5-r1" |
| 67 |
|
