Vulnerability from github – Published: 2020-09-04 17:59 – Updated: 2024-01-29 20:57
VLAI
Summary
Denial of Service in http-proxy
Details

Versions of http-proxy prior to 1.18.1 are vulnerable to Denial of Service. An HTTP request with a long body triggers an ERR_HTTP_HEADERS_SENT unhandled exception that crashes the proxy server. This is only possible when the proxy server sets headers in the proxy request using the proxyReq.setHeader function.

For a proxy server running on http://localhost:3000, the following curl request triggers the unhandled exception:
curl -XPOST http://localhost:3000 -d "$(python -c 'print("x"*1025)')"

Recommendation

Upgrade to version 1.18.1 or later

Severity
7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
