I. BACKGROUND
|
|
"osTicket is a widely-used open source support ticket system. It seamlessly
|
|
integrates inquiries created via email and web-based forms into a simple
|
|
easy to use multi-user web interface. Easily manage, organize and archive
|
|
all your support requests and responses in one place while providing your
|
|
clients with accountability and responsiveness they deserve." [1]
|
|
|
|
II. DETAILS
|
|
osTicket prior to v1.6 RC5 fails to validate / escape staff usernames which
|
|
can be abused to execute a blind sql injection attack by an unauthenticated
|
|
attacker.
|
|
|
|
The vendor has provided a new release v1.6 RC5 which addresses this vulnerability.
|
|
They have also provided patching instructions [2] should you be unable to perform
|
|
a full upgrade at this time.
|
|
|
|
One sample attack string might look similar to the following:
|
|
'+(SELECT IF(SUBSTRING(passwd,1,1)=CHAR(48),BENCHMARK(1000000,SHA1(1)),0) passwd
|
|
FROM ost_staff where staff_id=1) and '1'='1
