CVE-2022-22277Network attack vector

Wireless access point data disclosure via SNMP

Published Apr 27, 2022 · Updated Aug 3, 2024

Information disclosure in SonicWall SonicOS affected releases allows remote attackers to read wireless access point data through SNMP. SonicWall identifies the SNMP service and cleartext exposure but has not published the request, object identifier, or incorrect operation that returns the data. The service must be network-reachable, and the disclosed consequence is limited to confidentiality with no reported data modification or service interruption.
