The host is installed with Apache SSHD through 2.11.0, PuTTY before 0.80, WinSCP before 6.2.2, SecureCRT before 9.4.3, FileZilla before 3.66.4, OpenSSH before 9.6, Oracle Database Server 19c, or 21c and is prone to a security bypass vulnerability. A flaw is present in the application, which fails to properly handle issues in the SSH Binary Packet Protocol. Successful exploitation allows remote attackers to bypass integrity checks such that some packets are omitted, and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack.
