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 · unedited
Single 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 confidence

The 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.

MitigationImplement 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.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Wellchoose SSO Portal installation
    Locate the Wellchoose Single Sign On Portal System in your environment and confirm the product name matches exactly
    Affected if The product is Wellchoose Single Sign On Portal System and the version is less than iftop_p4_181
  2. Check the installed version
    Use the application's version check command, about page, or configuration files to determine the current version number
    Affected if The installed version is unknown or falls below iftop_p4_181
  3. Verify authenticated endpoint access
    Confirm that authenticated user accounts exist and the SSO portal admin/user endpoints are accessible on the network
    Affected if Authenticated endpoints are exposed and reachable
  4. Inspect input handling in SSO modules
    Review the SSO portal configuration and look for input fields in authenticated areas that interact with system commands or external executables
    Affected if The portal contains authenticated input fields that invoke system shell execution functions without proper sanitization
  5. Check for command injection vectors
    Examine logs or capture traffic to identify any user-supplied input being passed directly to system shell commands in SSO-related functions
    Affected 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.

Mitigation

Implement 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.
