Vulnerability Details

CVEID:   CVE-2024-24785
DESCRIPTION:   Golang Go could allow a remote attacker to bypass security restrictions, caused by a flaw in the MarshalJSON methods in the html/template package. By sending a specially crafted request, an attacker could exploit this vulnerability to inject unexpected content into templates.
CWE:   CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
CVSS Source:   IBM X-Force
CVSS Base score:   6.5
CVSS Vector:   (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N)

CVEID:   CVE-2023-48795
DESCRIPTION:   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.
