Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Firebird allows remote connections to the administrative account |
| 19 |
without verifying credentials. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Firebird is a multi-platform, open source relational database. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 dev-db/firebird < 2.0.3.12981.0-r6 >= 2.0.3.12981.0-r6 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Viesturs reported that the default configuration for Gentoo's init |
| 38 |
script ("/etc/conf.d/firebird") sets the "ISC_PASSWORD" environment |
| 39 |
variable when starting Firebird. It will be used when no password is |
| 40 |
supplied by a client connecting as the "SYSDBA" user. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker can authenticate as the "SYSDBA" user without |
| 46 |
providing the credentials, resulting in complete disclosure of all |
| 47 |
databases except for the user and password database (security2.fdb). |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Firebird users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot -v ">=dev-db/firebird-2.0.3.12981.0-r6" |
| 61 |
|
| 62 |
Note: /etc/conf.d is protected by Portage as a configuration directory. |
| 63 |
Do not forget to use "etc-update" or "dispatch-conf" to overwrite the |
| 64 |
"firebird" configuration file, and then restart Firebird. |
| 65 |
