Summary

Zoraxy: Authenticated Path Traversal in Config Import leads to RCE

Details

Authenticated Path Traversal to RCE via Configuration Import

Summary

An authenticated path traversal vulnerability in the configuration import endpoint allows an authenticated user to write arbitrary files outside the config directory, which can lead to RCE by creating a plugin.

Details

The vulnerable endpoint is POST /api/conf/import.

The zip entry names sanitization is bypassed by embedding ../ inside a longer sequence so the replacement produces a new ../:

conf/..././..././entrypoint.py
  → ReplaceAll("../", "")  (match found at index 1 of "..././", leaving "../")
  → conf/../../entrypoint.py   ← passes HasPrefix check, escapes conf/

Using this endpoint, a new plugin can be written (persistent) and the entrypoint (non-persistent) can be edited to add execution permissions to the plugin. When the database is provided in the import, the program should exit to trigger a container restart (which does not happen because the entrypoint does not monitor the Zoraxy exit code). As a result, the container was manually restarted for the PoC to work.

Impact

Arbitrary file write leads to RCE by an authenticated user. Given that the Docker socket might be mapped, this issue can lead to full host takeover.

Severity

3.3 (Low)

CVE-2026-33529 (GCVE-0-2026-33529)

Vulnerability from cvelistv5 – Published: 2026-03-26 19:26 – Updated: 2026-03-27 19:48

Title

Zoraxy: Authenticated Path Traversal in Config Import leads to RCE

Summary

Zoraxy is a general purpose HTTP reverse proxy and forwarding tool. Prior to version 3.3.2, an authenticated path traversal vulnerability in the configuration import endpoint allows an authenticated user to write arbitrary files outside the config directory, which can lead to RCE by creating a plugin. Version 3.3.2 patches the issue.

Severity

3.3 (Low)

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
