| Titel | TOTOLINK TOTOLINK NR1800X V9.1.0u.6279_B20210910 V9.1.0u.6279_B20210910 Buffer Overflow |
|---|
| Beschreibung | TOTOLINK NR1800X firmware V9.1.0u.6279_B20210910 contains an unauthenticated stack-based buffer overflow in the vendor-customized lighttpd binary (/usr/sbin/lighttpd). The issue is reachable in Form_Logout because userloginAuth() matches the URI with strstr("formLogout.htm") before authentication checks. A remote attacker can send a crafted request with an oversized Host header to trigger the overflow. |
