CVE-2023-35085Network attack vector

Unauthenticated code execution via SNMP integer overflow

Published Aug 10, 2023 · Updated Dec 4, 2024

Integer overflow in Ubiquiti UniFi Access Points and Switches allows remote attackers to execute code through SNMP Monitoring. Ubiquiti identifies the locus only as SNMP Monitoring and does not disclose the overflowing calculation, affected field, or function. The reachable gate is SNMP Monitoring with default settings enabled; successful exploitation runs attacker-controlled code on the appliance.
