Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Stefan Esser of the Hardened-PHP project discovered that Trac fails to |
| 39 |
validate the "id" parameter when uploading attachments to the wiki or |
| 40 |
the bug tracking system. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could exploit the vulnerability to upload arbitrary |
| 46 |
files to a directory where the webserver has write access to, possibly |
| 47 |
leading to the execution of arbitrary code. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Trac users should upgrade to the latest available version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=www-apps/trac-0.8.4" |
