CVE-2022-22783
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in Zoom On-Premise Meeting Connector Controller version 4.8.102.20220310 and On-Premise Meeting Connector MMR version 4.8.102.20220310 exposes process memory fragments to connected clients, which could be observed by a passive attacker.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an information disclosure vulnerability in Zoom On-Premise Meeting Connector Controller and MMR version 4.8.102.20220310 where process memory fragments are inadvertently exposed to connected clients. A passive network attacker observing traffic or receiving these exposed memory fragments could potentially extract sensitive information from the process memory space.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Zoom On-Premise Meeting Connector Controller installationLocate the Meeting Connector Controller component in your environment - typically installed on a dedicated server. Check installed software or service information to confirm presence.Affected if The component is present in the environment
-
Check Meeting Connector Controller versionInspect the installed version of the Zoom On-Premise Meeting Connector Controller. This may be visible in the software itself, associated service metadata, or version logs. Compare against 4.8.102.20220310.Affected if The installed version is exactly 4.8.102.20220310
-
Identify Zoom On-Premise Meeting Connector MMR installationLocate the Meeting Connector MMR (Multipoint Mixer Router) component in your environment. Check installed software or service information to confirm presence.Affected if The component is present in the environment
-
Check Meeting Connector MMR versionInspect the installed version of the Zoom On-Premise Meeting Connector MMR. This may be visible in the software itself, associated service metadata, or version logs. Compare against 4.8.102.20220310.Affected if The installed version is exactly 4.8.102.20220310
-
Assess network accessibility of affected componentsDetermine whether the Meeting Connector Controller and MMR components are network-accessible to client systems. Review firewall rules, network segmentation, and access policies controlling client connections to these components.Affected if The components are network-accessible to clients (the vulnerability allows passive attackers to receive exposed memory fragments via client connections)
You are affected if either the Meeting Connector Controller or MMR component is exactly version 4.8.102.20220310 AND is accessible to network clients, since the flaw allows process memory fragments to be exposed to connected clients.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of Zoom On-Premise Meeting Connector (both Controller and MMR components) as specified in Zoom's security advisory. If immediate patching is not feasible, implement strict network access controls and segment the affected components to limit client exposure.
