Description
Ikaros 1.2.0 through 1.2.5 contains an authentication bypass vulnerability that allows attackers with a valid password to skip TOTP verification by reusing the login temp token. Attackers can present the temp token from the jwt/apply endpoint as a bearer JWT, refresh it, or use HTTP Basic login to gain full account access, including the master administrator.
