arbitrary code. |

Description |
35 |
=========== |
36 |
|
37 |
Multiple vulnerabilities have been reported in Nagios: |
38 |
|
39 |
* Paul reported that statuswml.cgi does not properly sanitize shell |
40 |
metacharacters in the (1) ping and (2) traceroute parameters |
41 |
(CVE-2009-2288). |
42 |
|
43 |
* Nagios does not properly verify whether an authenticated user is |
44 |
authorized to run certain commands (CVE-2008-5027). |
45 |
|
46 |
* Andreas Ericsson reported that Nagios does not perform validity |
47 |
checks to verify HTTP requests, leading to Cross-Site Request Forgery |
48 |
(CVE-2008-5028). |
49 |
|
50 |
* An unspecified vulnerability in Nagios related to CGI programs, |
51 |
"adaptive external commands," and "writing newlines and submitting |
52 |
service comments" has been reported (CVE-2008-6373). |
53 |
|
54 |
Impact |
55 |
====== |
56 |
|
57 |
A remote authenticated or unauthenticated attacker may exploit these |
58 |
vulnerabilities to execute arbitrary commands or elevate privileges. |
59 |
|
60 |
Workaround |
61 |
========== |
62 |
|
63 |
There is no known workaround at this time. |
64 |
|
65 |
Resolution |
66 |
========== |
67 |
|
68 |
All Nagios users should upgrade to the latest version: |
69 |
|
70 |
# emerge --sync |
71 |
# emerge --ask --oneshot -v ">=net-analyzer/nagios-core-3.0.6-r2" |
72 |
|
73 |
NOTE: Users of the Nagios 2 branch can update to version 2.12-r1 which |
74 |
contains a patch to fix CVE-2009-2288. However, that branch is not |
75 |
supported upstream or in Gentoo and we are unaware whether the other |
76 |
vulnerabilities affect 2.x installations. |
