An issue was discovered in Ada Web Server 20.0. When configured to use SSL (which is not the default setting), the SSL/TLS used to establish connections to external services is done without proper hostname validation. This is exploitable by man-in-the-middle attackers.

An issue was discovered in AdaCore ada_web_services 20.0 allows an attacker to escalate privileges and steal sessions via the Random_String() function in the src/core/aws-utils.adb module.

AdaCore Ada Web Services (AWS) before 2.10.2 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
