JBB SQL inj. vuln.

JBB SQL inj. vuln.

Vuln. dicovered by : r0t
Date: 28 nov. 2005
Vendor:http://www.joelh.de/jbb/
affected version: jbb 0.9.9rc3 and prior

Vuln. description:
Input passed to the "nr" parameter in "topiczeigen.php", "forum" "zeigeseite" in "showforum.php", "forum" in "newtopic.php", "tidnr" in "neuerbeitrag.php" isn't properly sanitised before being used in a SQL query.This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

examples:
/topiczeigen.php?nr=[SQL]
/showforum.php?forum=[SQL]
/showforum.php?forum=1&zeigeseite=[SQL]
/newtopic.php?forum=[SQL]
/neuerbeitrag.php?tidnr=[SQL]

Solution:
Edit the source code to ensure that input is properly sanitised.
