Known Issue: The Mastercard Payment Gateway Virtual Payment Client (VPC) API that uses the MD5 based cryptogram to provide an integrity check of request parameters contains a critical vulnerability that allows limited modification of those parameters without causing a change in the cryptogram value. This vulnerability is remotely exploitable and does not require authentication. Mastercard has assessed the severity as CVSS 7.5. Mastercard recommends all customers to update their integration to use the HmacSHA256 based cryptogram, which is not vulnerable to parameter tampering. We thank Yohanes Nugroho for his support to identify this security vulnerability to protect our customers.
