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.

https://notcve.org/view.php?id=CVE-2023-36049
.NET, .NET Framework, and Visual Studio Elevation of Privilege Vulnerability Vulnerabilidad de elevación de privilegios en .NET, .NET Framework y Visual Studio A vulnerability was found in FormatFtpCommand in the .NET package that may result in a CRLF injection arbitrary file write and deletion. This vulnerability allows remote attackers to create or delete arbitrary files on FTP servers implemented using affected versions of Microsoft .NET. Interaction with the .NET framework is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the FormatFtpCommand method. The issue results from the incorrect neutralization of CRLF sequences. An attacker can leverage this vulnerability to write or delete files in the context of the FTP server. • https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-36049 https://access.redhat.com/security/cve/CVE-2023-36049 https://bugzilla.redhat.com/show_bug.cgi?id=2248883 • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •
