CVE-2026-70555 · Severity: medium · CVSS 6.5 · Published 2026-11-09

rConfig Core is a configuration management system that stores SSH, Telnet, and enable passwords for managed network devices. An authenticated user can retrieve cleartext credentials for all managed devices through the REST API due to missing authorization checks and automatic decryption, allowing an attacker to exfiltrate stored plaintext credentials and compromise managed infrastructure.

Technologies: [rConfig Core](https://junglewise.ai/threats/technologies/rconfig-core). Vendors: [Rconfig](https://junglewise.ai/threats/vendors/rconfig).

## How to fix

- Fixed in rConfig Core 8.2.13

## Technical details

The vulnerability exists in the device-credentials API endpoints (GET /api/device-credentials, GET /api/device-credentials/{id}, and GET /api/v1/device-credentials) which automatically decrypt stored credentials on read without performing proper authorization checks. An authenticated user with any valid token (including those seeded as the administrator account) can statelessly request these endpoints to retrieve all plaintext device passwords. The external v1 API endpoint accepts any valid token as the seeded administrator account, bypassing expected access controls.

## Affected products

- rConfig Core 8.2.3 to before 8.2.13

## Timeline

- 2026-11-09: disclosed
- 2026-08-10: patched: rConfig Core 8.2.13 released with credential masking in v1 API
