CVE-2026-1428
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 · uneditedSingle Sign-On Portal System developed by WellChoose has a OS Command Injection vulnerability, allowing authenticated remote attackers to inject arbitrary OS commands and execute them on the server.
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 confidenceThe WellChoose Single Sign-On Portal System contains an OS Command Injection vulnerability in its authenticated endpoints. Attackers with valid credentials can inject arbitrary OS commands through unsanitized input fields that get passed to system shell execution functions, leading to complete server compromise.

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 the Wellchoose SSO Portal installationLocate the Wellchoose Single Sign On Portal System in your environment and confirm the product name matches exactlyAffected if The product is Wellchoose Single Sign On Portal System and the version is less than iftop_p4_181
-
Check the installed versionUse the application's version check command, about page, or configuration files to determine the current version numberAffected if The installed version is unknown or falls below iftop_p4_181
-
Verify authenticated endpoint accessConfirm that authenticated user accounts exist and the SSO portal admin/user endpoints are accessible on the networkAffected if Authenticated endpoints are exposed and reachable
-
Inspect input handling in SSO modulesReview the SSO portal configuration and look for input fields in authenticated areas that interact with system commands or external executablesAffected if The portal contains authenticated input fields that invoke system shell execution functions without proper sanitization
-
Check for command injection vectorsExamine logs or capture traffic to identify any user-supplied input being passed directly to system shell commands in SSO-related functionsAffected if User input from authenticated sessions is being passed to shell execution functions without validation
You are affected if Wellchoose Single Sign On Portal System is installed with a version below iftop_p4_181 and authenticated users can access endpoints that pass unsanitized input to system shell commands.

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 · scopedImplement strict input validation and whitelist approaches, replace dynamic command execution with parameterized APIs or library calls, and apply principle of least privilege to the application service account.
