Exploitation Probability (EPSS)

Low risk
0.36%

29th percentile - higher than 29% of all known CVEs

Summary

In openhole 0.1.1 and earlier, the server forwarded r.URL.Path instead of the original request target, allowing percent-encoded dot segments and separators to perform path traversal in tunneled local services.

Risk Assessment

An attacker can access local files and services beyond the intended tunnel, leading to data confidentiality and integrity breaches.

Recommendation

Update openhole to version 0.1.2 or later, which includes a fix preventing path traversal.

Original NVD description (English source)

openhole exposes localhost to the internet in one command. In 0.1.1 and earlier, openhole-server in internal/server/public_proxy.go forwarded r.URL.Path instead of preserving the original request target with r.URL.EscapedPath(), allowing percent encoded dot segments %2e and separators %2f to reach tunneled local services as ../ and / for path traversal. This issue is fixed in version 0.1.2.
