Description:
nCipher has reported a vulnerability in payShield, possibly allowing malicious people to make unauthorised purchases.
The problem is that the SPP library makes a "SPP_VerifyPVV()" function call every three minutes, which return a "Status_OK". This could be exploited by malicious people by making a large number of requests over a period of time.
The vulnerability has been reported in applications linking against SPP library versions 1.3.12, 1.5.18, and 1.6.18.
Solution:
Link applications against a newer version of the SPP library.
Provided and/or discovered by:
Reported by vendor.
