An issue was discovered in IO FinNet tss-lib before 2.0.0. The parameter ssid for defining a session id is not used through the MPC implementation, which makes replaying and spoofing of messages easier. In particular, the Schnorr proof of knowledge implemented in sch.go does not utilize a session id, context, or random nonce in the generation of the challenge. This could allow a malicious user or an eavesdropper to replay a valid proof sent in the past.

Missing Token Replay Detection

Saml2 Authentication services for ASP.NET (NuGet package Sustainsys.Saml2) greater than 2.0.0, and less than version 2.5.0 has a faulty implementation of Token Replay Detection. Token Replay Detection is an important defence in depth measure for Single Sign On solutions. The 2.5.0 version is patched. Note that version 1.0.1 is not affected. It has a correct Token Replay Implementation and is safe to use.

A vulnerability has been identified in Mendix Applications using Mendix 10 (All versions < V10.4.0), Mendix Applications using Mendix 7 (All versions < V7.23.37), Mendix Applications using Mendix 8 (All versions < V8.18.27), Mendix Applications using Mendix 9 (All versions < V9.24.10). A capture-replay flaw in the platform could have an impact to apps built with the platform, if certain preconditions are met that depend on the app's model and access control design. This could allow authenticated attackers to access or modify objects without proper authorization, or escalate privileges in the context of the vulnerable app.
