Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
An input sanitation error in PEAR Net_Traceroute might allow remote |
| 19 |
attackers to execute arbitrary commands. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
PEAR Net_Traceroute is an OS independent wrapper class for executing |
| 25 |
traceroute calls from PHP. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-php/PEAR-Net_Traceroute < 0.21.2 >= 0.21.2 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Pasquale Imperato reported that the $host parameter to the traceroute() |
| 39 |
function in Traceroute.php is not properly sanitized before being |
| 40 |
passed to exec(). |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could exploit this vulnerability when user input is |
| 46 |
passed directly to PEAR Net_Traceroute in a PHP script, possibly |
| 47 |
resulting in the remote execution of arbitrary shell commands with the |
| 48 |
privileges of the user running the affected PHP script. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
Ensure that all data that is passed to the traceroute() function is |
| 54 |
properly shell escaped (for instance using the escapeshellcmd() |
| 55 |
function). |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All PEAR Net_Traceroute users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose |
| 64 |
">=dev-php/PEAR-Net_Traceroute-0.21.2" |
| 65 |
|
