Summary

Appium Java Client from version 8.2.1 to 10.1.0 has a vulnerability in the directConnect mechanism. When directConnect(true) is enabled, the client reads directConnectHost, directConnectPort, and directConnectPath from the NEW_SESSION response and rebuilds the server URL, validating only the https protocol. A malicious server can redirect traffic to any destination, enabling session interception and SSRF attacks on internal hosts.

Risk Assessment

The risk includes full interception of test session traffic and credential theft from cloud metadata (IMDS) via SSRF.

Recommendation

Upgrade Appium Java Client to version 10.1.1, which fixes the issue.

Original NVD description (English source)

Appium Java Client is the Java language binding for writing Appium tests that conform to the W3C WebDriver protocol. From 8.2.1 until 10.1.1, when directConnect(true) is enabled, AppiumCommandExecutor.setDirectConnect() reads the directConnectHost, directConnectPort, and directConnectPath fields from the server's NEW_SESSION response and rebuilds the client's server URL from them, validating only that the protocol is https, with no host allowlist or IP validation; a rogue or compromised server can therefore redirect all subsequent session traffic to an arbitrary destination, enabling full interception of session traffic and a server-side request forgery pivot to internal hosts, including cloud metadata (IMDS) credential theft. This vulnerability is fixed in 10.1.1.
