CVE-2026-3422
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 · uneditedU-Office Force developed by e-Excellence has a Insecure Deserialization vulnerability, allowing unauthenticated remote attackers to execute arbitrary code on the server by sending maliciously crafted serialized content.
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 confidenceU-Office Force by e-Excellence contains an insecure deserialization vulnerability where the application deserializes untrusted data without proper validation. An unauthenticated attacker can send maliciously crafted serialized content (e.g., PHP object injection, Java serialized objects, or similar) to achieve remote code execution on the server.

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 U-Office Force versionLocate the application version through the product's built-in about page, admin panel, or version information file typically found in the installation directory. Check the vendor documentation for version lookup methods specific to Edetw U Office Force.Affected if The installed version is lower than 29.50 or exactly equals 29.50
-
Confirm application network exposureDetermine if the U-Office Force web interface or API endpoints are accessible from untrusted networks or the internet. Review firewall rules, reverse proxy configurations, and network ACLs controlling access to the application.Affected if The application is directly exposed to unauthenticated network attackers without proper network segmentation or authentication barriers
-
Identify deserialization endpointsReview application documentation or traffic logs to identify endpoints that accept serialized data (Java serialized objects, PHP serialized data, or similar). Common indicators include content-type headers like application/x-java-serialized-object or usage of deserialization functions in application code.Affected if The application processes serialized data from unauthenticated requests without class whitelisting or input validation
A user is affected if their U-Office Force installation is version 29.50 or below and the application is accessible to unauthenticated attackers who can send malicious serialized payloads to deserialization endpoints.

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 data29.50
Replace insecure deserialization mechanisms with safe alternatives such as JSON, implement whitelisting for allowed classes, or use secure serialization libraries with integrity checks.
