CVE-2022-22783Network attack vector

Process memory disclosure via uninitialized variable

Published Apr 28, 2022 · Updated Sep 17, 2024

Information disclosure in Zoom Meeting Connector Controller and MMR 4.8.102.20220310 allows remote authenticated users to read process memory. Zoom attributes the exposure to a variable that is used without initialization, causing fragments of server-process memory to be included in client-visible data. The affected client must be connected to the on-premise service; published material does not identify the variable, code locus, or data types exposed.
