CVE-2022-30981
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 · uneditedAn issue was discovered in Gentics CMS before 5.43.1. By uploading a malicious ZIP file, an attacker is able to deserialize arbitrary data and hence can potentially achieve Java code execution.
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 confidenceGentics CMS before 5.43.1 contains an insecure deserialization vulnerability where uploading a malicious ZIP file allows attackers to deserialize arbitrary data, potentially achieving arbitrary Java code execution.

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 Gentics CMS installed versionLocate the Gentics CMS installation directory and check the version file or system information. Typical locations include the admin panel, version manifest, or the cms-core jar/war file properties.Affected if The installed version is lower than 5.43.1
-
Verify ZIP file upload functionality is accessibleCheck if the file upload feature that accepts ZIP archives is enabled and exposed in the Gentics CMS web interface or API endpoints.Affected if ZIP upload functionality is enabled and accessible to users
-
Confirm Java deserialization is in useInspect the Gentics CMS configuration files (such as application.properties or web.xml) to determine if Java object deserialization is configured for handling uploaded ZIP files.Affected if The system uses Java deserialization for processing uploaded ZIP files without strict type filtering
-
Check network exposure of upload endpointsReview the web server or reverse proxy configuration to determine if the file upload endpoints are exposed to untrusted users or the public internet.Affected if Upload endpoints are reachable from untrusted network segments or the internet
A system is affected if it runs Gentics CMS version 5.43.0 or earlier AND has ZIP file upload functionality enabled and accessible, allowing deserialization of malicious payload data.
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 · scoped5.43.1
Upgrade to Gentics CMS version 5.43.1 or later. Until upgrade is possible, disable or restrict ZIP file upload functionality and implement strict input validation on the server side.
Gentics CMS 5.43.1
- Upgrade Gentics CMS to version 5.43.1 or later to address the deserialization vulnerability
- Verify the upgrade in a staging environment before deploying to production
- After upgrading, ensure that ZIP file upload functionality is properly tested to confirm the vulnerability is resolved
