CVE-2022-44608
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 · uneditedUncontrolled resource consumption vulnerability in Cybozu Remote Service 4.0.0 to 4.0.3 allows a remote authenticated attacker to consume huge storage space, which may result in a denial-of-service (DoS) condition.
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 · high confidenceUncontrolled resource consumption vulnerability in Cybozu Remote Service versions 4.0.0 to 4.0.3 allows a remote authenticated attacker to consume excessive storage space through unspecified vectors, potentially leading to disk exhaustion and denial of service.

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 installed Cybozu Remote Service versionCheck the product version through the system administration console, installed programs list, or product-specific version query command provided by Cybozu Remote ServiceAffected if The installed version is 4.0.0, 4.0.1, 4.0.2, or 4.0.3
-
Verify the product is exposed to network accessConfirm that Cybozu Remote Service is accessible from network segments accessible to authenticated users or potential attackersAffected if The service is reachable without additional network isolation or authentication barriers beyond the application login
-
Review storage consumption patternsMonitor disk space usage on the server hosting Cybozu Remote Service, looking for abnormal or rapid growth in storage usage that cannot be attributed to legitimate dataAffected if Unexpected storage growth is observed that correlates with user activity or occurs without clear cause
You are affected if Cybozu Remote Service version 4.0.0 through 4.0.3 is installed and the service is network-accessible to authenticated users.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedUpgrade Cybozu Remote Service to version 4.0.4 or later which contains the fix, and implement storage quotas or monitoring to detect abnormal storage consumption patterns.
Cybozu Remote Service 4.0.4 or later
- Upgrade Cybozu Remote Service to a version newer than 4.0.3 to remediate the uncontrolled resource consumption vulnerability.
- Verify the upgrade in a test environment before deploying to production.
- After upgrading, monitor storage usage to confirm the vulnerability is mitigated.
