From adde92f6f1283959effbf74cee5bfb8f0f6f8176 Mon Sep 17 00:00:00 2001 From: David Cook Date: Mon, 13 Jul 2015 14:06:46 +1000 Subject: [PATCH] Bug 14521 - SQL injection in local use system preferences This patch fixes a SQL injection vulnerability in the local use system preferences. _TEST PLAN_ Before applying: 1) Go to Global System Preferences 2) Click on the "Local use" tab 3) Add a new preference with the value "') or '1' = '1' -- " (be sure to include the space at the end after the comment --). 4) When the page refreshes, you should now see about 99 other system preferences which shouldn't be showing up. 5) Apply the patch 6) Refresh the page 7) Note that you now only see a system preference for "') or '1' = '1' -- " and the other actual local use system preferences.
