Multiple NETGEAR Smart Switches Vulnerable to Input Validation Errors

GC108P and other smart switch products from Netgear, U.S.A. Several of Netgear's smart switches are vulnerable to an input validation error, which stems from a failure of the daemon to check for validation when an authentication TLV is missing from an incoming NSDP packet. An unauthenticated...

CVE-2021-40866: Undefined Security Weakness

Certain NETGEAR smart switches are affected by a remote admin password change by an unauthenticated attacker via the disabled by default /sqfs/bin/sccd daemon, which fails to check authentication when the authentication TLV is missing from a received NSDP packet. This affects GC108P before 1.0.8....

lldpd: buffer overflow in the lldp_decode function in daemon/protocols/lldp.c

A buffer overflow was found in the lldpdecode function in daemon/protocols/lldp.c in lldpd. This flaw allows remote attackers to cause a denial of service daemon crash and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries. This threatens the...
