Internet Bug Bounty: TLS client authentication can be bypassed due to ticket resumption

The TLS client authentication can be bypassed due to ticket resumption. The issue was that TLS session tickets were not properly isolated for multiple virtual hosts in one server. This allowed a ticket issued for one virtual host to be resumed at a different virtual host, circumventing client...

The vulnerability of the Secure Client Authentication (SCA) server, a software solution for voice call authentication and message exchange in BlackBerry SecuSUITE, allows attackers to circumvent security restrictions and execute brute-force attacks.

The vulnerability of the Secure Client Authentication SCA server, a software solution for voice call authentication and message exchange, developed by BlackBerry SecuSUITE, stems from the lack of limits on the number of authentication attempts. Exploiting this vulnerability allows a malicious act...

lxd CA certificate sign check bypass

Summary If a server.ca file is present in LXDDIR at LXD start up, LXD is in "PKI mode". In this mode, only TLS clients that have a CA-signed certificate should be able to authenticate with LXD. We have discovered that if a client that sends a non-CA signed certificate during the TLS handshake, th...
