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 that allows authenticated remote attackers to inject and execute arbitrary operating system commands on the server through the application.

MitigationImplement strict input validation and sanitization for all user-supplied parameters, and use parameterized APIs or safe library functions instead of constructing OS commands from user input.

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 if WellChoose SSO Portal is installed
    Check for WellChoose Single Sign-On Portal System in your environment. Look for web services running on common ports (80, 443, 8080) that present a WellChoose SSO login page, or check installed software listings for WellChoose components.
    Affected if The product is present in the environment
  2. Determine the installed version
    Access the admin interface, check the system information page, or review installation/upgrade documentation files for the version number. Compare the version against the threshold 'iftop_p4_181'.
    Affected if Version is lower than iftop_p4_181 (e.g., iftop_p4_180, iftop_p3_xxx, or any version number that comes before iftop_p4_181)
  3. Verify if the web interface is network-accessible
    Check firewall rules, network configurations, and reverse proxies to determine if the SSO portal web interface is accessible from network segments outside the trusted internal network.
    Affected if The portal is exposed to untrusted networks
  4. Confirm authentication is required for the vulnerable parameter
    Review access controls and authentication requirements for the SSO portal. The vulnerability requires an authenticated session - check if default credentials are in use or if weak authentication is configured.
    Affected if Authentication can be obtained (valid credentials exist, default credentials work, or authentication is weak/bypassable)

The environment is affected if WellChoose SSO Portal System is installed with a version lower than iftop_p4_181, the web interface is accessible, and an attacker can obtain valid authentication credentials.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement strict input validation and sanitization for all user-supplied parameters, and use parameterized APIs or safe library functions instead of constructing OS commands from user input.

Recommended fix Moderate confidence

iftop_p4_181 or later

  1. 1. Identify the current version of the Single Sign-On Portal System by WellChoose currently deployed in your environment.
  2. 2. Contact WellChoose vendor directly to obtain the fixed release (iftop_p4_181 or later) and any upgrade packages.
  3. 3. Review any release notes or documentation provided by the vendor for the fixed version.
  4. 4. Perform a full backup of the current SSO Portal System configuration, database, and related data.
  5. 5. Test the upgrade in a non-production/staging environment first to verify functionality.
  6. 6. Schedule a maintenance window and apply the upgrade to production systems.
  7. 7. After upgrade, verify that the OS Command Injection vulnerability is no longer present.
  8. 8. Monitor the system for any anomalies post-upgrade.
