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
