By manipulating sequence numbers during the handshake, an attacker can remove the initial messages on the secure channel without causing a MAC failure. For example, an attacker could disable the ping extension and thus disable the new countermeasure in OpenSSH 9.5 against keystroke timing attacks.", "title": "Vulnerability description" }, { "category": "summary", "text": "ssh: Prefix truncation attack on Binary Packet Protocol (BPP)", "title": "Vulnerability summary" }, { "category": "other", "text": "This CVE is classified as moderate because the attack requires an active Man-in-the-Middle (MITM) who can intercept and modify the connection\u0027s traffic at the TCP/IP layer.\n\nAlthough the attack is cryptographically innovative, its security impact is fortunately quite limited. It only allows the deletion of consecutive messages, and deleting most messages at this protocol stage prevents user authentication from proceeding, leading to a stalled connection.\n\nThe most significant identified impact is that it enables a MITM to delete the SSH2_MSG_EXT_INFO message sent before authentication begins. This allows the attacker to disable a subset of keystroke timing obfuscation features. However, there is no other observable impact on session secrecy or session integrity.", "title": "Statement" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not

\"kex-strict-c-v00@openssh.com\" is not provided by clients or \"kex-strict-s-v00@openssh.com\" is absent in the server\u0027s reply, you can disable the following ciphers and HMACs as a workaround on

through crypto-policies, one can apply a subpolicy with the following content:\n```\ncipher@SSH = -CHACHA20-POLY1305\nssh_etm = 0\n```\ne.g., by putting these lines into `/etc/crypto-policies/policies/modules/CVE-2023-48795.pmod`, applying the resulting subpolicy with `update-crypto-policies --set $(update-crypto-policies --show):CVE-2023-48795` and restarting openssh server.\n\nOne can verify that the changes are in effect by ensuring the ciphers listed above are missing from both `/etc/crypto-policies/back-ends/openssh.config` and `/etc/crypto-policies/back-ends/opensshserver.config`.\n\nFor more details on using crypto-policies, please refer to https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/security_hardening/using-the-system-wide-cryptographic-policies_security-hardening\n\nNote that this procedure does limit the interoperability of the host and is only suggested as a temporary mitigation until the issue is fully resolved with an update.\n\nFor RHEL-7: \nWe can recommend to use strict MACs and Ciphers on RHEL7 in both files /etc/ssh/ssh_config and /etc/ssh/sshd_config.\n\nBelow strict set of Ciphers and MACs can be used as mitigation for RHEL 7.\n\n```\nCiphers
