CVE-2020-7043

OpenFortiVPN (openfortivpn) 1.11.0 with OpenSSL before 1.0.2 is vulnerable to CVE-2020-7043. In tunnel.c, hostname validation mishandles null bytes, allowing a crafted hostname like good.example.com\x00evil.example.com to bypass validation. This affects builds using affected OpenSSL versions and ...

CVE-2020-7042

CVE-2020-7042 affects openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. In tunnel.c, the hostname check operates on uninitialized memory, causing certificate validation to malfunction and resulting in a valid certificate never being accepted (only malformed certs may be accepted). The is...

CVE-2020-7041

CVE-2020-7041

CVE-2020-7041 affects openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later; tunnel.c incorrectly treats an X509_check_host negative error as success, bypassing certificate hostname validation. This can permit an attacker to misverify credentials. Public advisories indicate fixes in later ope...
