CVE-2023-30312 (GCVE-0-2023-30312)

Vulnerability from cvelistv5 – Published: 2024-05-28 00:00 – Updated: 2024-11-07 11:15
VLAI
Summary
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.
