Description:
Justin Samuel has reported a security issue in ModernBill, which can be exploited by malicious people to conduct man-in-the-middle (MITM) attacks.
The problem is caused due to the application calling CURL with CURLOPT_SSL_VERIFYPEER
and CURLOPT_SSL_VERIFYHOST set to false when communicating with a payment gateway over SSL. This causes the CURL library to not properly verifying the peer's certificate and can potentially be exploited in a man-in-the-middle attack to decrypt all communications between ModernBill and the payment gateway.
The security issue has been reported in version 5.0.1. Other versions may also be affected.
Solution:
The security issue has been fixed in version 5.0.4 by introducing a configuration setting.
