What is CVE-2023-30312?
CVE-2023-30312 is a high-severity vulnerability in n/a, published on 28 May 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
An issue discovered in OpenWrt 18.06, 19.07, 21.02, 22.03, and beyond allows off-path attackers to hijack TCP sessions, which could lead to a denial of service, impersonating the client to the server (e.g., for access to files over FTP), and impersonating the server to the client (e.g., to deliver false information from a finance website). This occurs because nf_conntrack_tcp_no_window_check is true by default.
Weakness: CWE-203
