Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to 2.3.2, the POST /host/db/proxy/test endpoint accepts the singleProxy, proxyChain, and testTarget request fields without validating their destination addresses. The testProxyConnectivity path uses raw TCP and SOCKS connections to attacker-selected hosts and ports, allowing an authenticated user to probe localhost, private networks, link-local metadata services, and other infrastructure reachable from the Termix server. Structured connection errors disclose host reachability and timing information, and successful metadata access can expose cloud credentials. This issue is fixed in version 2.3.2.

AI Analysis

Impact

Termix’s POST /host/db/proxy/test endpoint accepts proxy configuration parameters without validating destination addresses, allowing an authenticated user to open raw TCP or SOCKS connections to any host and port reachable from the Termix server. This enables the user to probe localhost, private networks, and cloud metadata services, with error messages revealing reachability and timing information. Successful access to metadata endpoints can expose cloud credentials, while arbitrary internal hosts can be contacted, making it a classic SSRF flaw (CWE‑918).

Affected Systems

The vulnerability affects Termix server‑management platform versions prior to 2.3.2. Any deployment running an older release is susceptible; the issue is fixed in the 2.3.2 release.

Risk and Exploitability

The CVSS score of 7.7 indicates high severity, but the EPSS score is not available and it is not listed in the CISA KEV catalog. Exploitation requires a legitimate authenticated session; the attack vector is a Server‑Side Request Forgery via the proxy test endpoint. Once authenticated, an attacker can execute arbitrary connectivity tests to internal hosts, glean metadata, and potentially exfiltrate credentials from cloud environments.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Termix to version 2.3.2 or later, which contains the required input validation fix.
  • Restrict or disable the /host/db/proxy/test endpoint for untrusted users or enforce access control so only privileged administrators can invoke it.
  • Implement network segmentation or firewall rules that block the Termix server from reaching internal IP ranges or cloud metadata service addresses.
