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 SS1 installed versionLocate the SS1 application and check its version information through the software's built-in about dialog, installation directory version file, or by querying the application via its administrative interface or command-line tool if available.Affected if The installed version is 16.0.0.10 or any earlier version.
-
Confirm file upload functionality is accessibleReview the SS1 configuration settings or service documentation to determine whether the file upload module or endpoint is enabled and accessible. This may be found in the web interface, configuration files, or by reviewing exposed API endpoints.Affected if The file upload feature is enabled and exposed without authentication.
-
Verify network exposure of SS1 serviceDetermine which network interfaces and ports the SS1 service is bound to by reviewing service configuration, firewall rules, or network binding settings. Check if the service is listening on public-facing IP addresses or only on internal interfaces.Affected if The SS1 service is directly accessible from untrusted networks or the internet without network-level access controls.
A system is affected if SS1 version 16.0.0.10 or earlier is installed, the file upload functionality is enabled, and the service is exposed to untrusted network access.
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 · scopedImmediately upgrade to a version newer than 16.0.0.10, apply available patches, and implement network-level access controls to restrict exposure of the affected service to untrusted networks until the fix is applied.
Contact vendor for fixed release (version higher than 16.0.0.10)
- Identify the current installed version of SS1 by checking the application or system documentation
- Contact the vendor (DOS Office Osaka) directly or visit their official website (www.dos-osaka.co.jp) to obtain the patched version
- Obtain the fixed release which addresses CVE-2025-54762 - the vendor has released a patch for this critical unrestricted file upload vulnerability
- Apply the vendor-provided patch or upgrade to the fixed version following their official installation instructions
- Verify the patch was applied successfully and the vulnerability is remediated
