CVSS: 5.9EPSS: 96%CPEs: 79EXPL: 1CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), 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. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Software Foundation Apache MINA. In SFTP servers implemented using Apache MINA SSHD that use a RootedFileSystem, logged users may be able to discover "exists/does not exist" information about items outside the rooted tree via paths including parent navigation ("..") beyond the root, or involving symlinks. This issue affects Apache MINA: from 1.0 before 2.10. Users are recommended to upgrade to 2.10 A flaw was found in Apache Mina SSHD that could be exploited on certain SFTP servers implemented using the Apache Mina RootedFileSystem. This issue could permit authenticated users to view information outside of their permissions scope. • https://lists.apache.org/thread/b9qgtqvhnvgfpn0w1gz918p21p53tqk2 https://access.redhat.com/security/cve/CVE-2023-35887 https://bugzilla.redhat.com/show_bug.cgi?id=2240036 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
