CVE-2021-40867

Public Exploit

Description

Certain NETGEAR smart switches are affected by an authentication hijacking race-condition vulnerability by an unauthenticated attacker who uses the same source IP address as an admin in the process of logging in (e.g., behind the same NAT device, or already in possession of a foothold on an admin's machine). This occurs because the multi-step HTTP authentication process is effectively tied only to the source IP address. This affects GC108P before 1.0.8.2, GC108PP before 1.0.8.2, GS108Tv3 before 7.0.7.2, GS110TPP before 7.0.7.2, GS110TPv3 before 7.0.7.2, GS110TUP before 1.0.5.3, GS308T before 1.0.3.2, GS310TP before 1.0.3.2, GS710TUP before 1.0.5.3, GS716TP before 1.0.4.2, GS716TPP before 1.0.4.2, GS724TPP before 2.0.6.3, GS724TPv2 before 2.0.6.3, GS728TPPv2 before 6.0.8.2, GS728TPv2 before 6.0.8.2, GS750E before 1.0.1.10, GS752TPP before 6.0.8.2, GS752TPv2 before 6.0.8.2, MS510TXM before 1.0.4.2, and MS510TXUP before 1.0.4.2.
