CVE-2021-29004: rConfig 3.9.6 is affected by SQL Injection.

rConfig 3.9.6 is affected by SQL Injection. A user must be authenticated to exploit the vulnerability. If --secure-file-priv in MySQL server is not set and the Mysql server is the same as rConfig, an attacker may successfully upload a webshell to the server and access it remotely.

Security readout for executives and security teams

Plain-English summary

CVE-2021-29004 is an authenticated SQL injection in rConfig 3.9.6. The public description says it can, under specific MySQL conditions, lead to remote webshell access. Because rConfig manages network configuration data, a compromised instance could create operational and security risk beyond the application itself.

Executive priority

Treat as high priority if rConfig 3.9.6 is in use, especially on systems managing network device configurations. The main decision is rapid containment and vendor-guided remediation, not broad panic.

Technical view

The CVE describes SQL injection reachable by an authenticated user in rConfig 3.9.6. If MySQL runs on the same host and --secure-file-priv is not set, the issue may allow writing a webshell and remote access. No CVSS, CWE, vendor advisory, or patch details are provided in the bundle.

Likely exposure

Organizations running rConfig 3.9.6 are the stated exposure. Risk is higher where untrusted users can authenticate and MySQL is co-hosted with permissive file-write settings.

Exploitation context

The bundle includes public proof-of-concept references, but KEV is false and no cited source states active exploitation. Exploitation requires authentication, and webshell impact depends on the MySQL deployment conditions described in the CVE.

Researcher notes

Evidence is limited to the CVE description and public PoC links. The affected product is identified as rConfig 3.9.6, but the bundle lacks CVSS, exact vulnerable endpoint details, patch status, and vendor-confirmed remediation.

Mitigation direction

  • Check rConfig vendor guidance for fixed versions or supported remediation.
  • Prioritize upgrade or replacement if rConfig 3.9.6 is present.
  • Restrict rConfig access to trusted administrative networks and users.
  • Review MySQL secure-file-priv exposure with database administrators.
  • Monitor the rConfig host for unexpected web files or process activity.

Validation and detection

  • Inventory rConfig deployments and confirm whether version 3.9.6 is running.
  • Review rConfig user accounts for unnecessary or untrusted access.
  • Confirm whether MySQL is co-hosted with the rConfig server.
  • Check MySQL secure-file-priv configuration against vendor guidance.
  • Review web server and application logs for suspicious authenticated activity.
