Website with the vulnerability information blastradius.fail The original vulnerability has been assigned CVE-2024-3596 Case in vince: https://kb.cert.org/vuls/id/456537
There is no known proof-of-concept except for the attack shown in the paper from the researchers
An attacker can trigger an authentication flow with a RADIUS-backed token, intercept the RADIUS packet sent by eduMFA and modify the RADIUS server's answer, which would lead eduMFA to believe that the token is valid, even though the RADIUS servers answer was a reject.
