Improper Request Routing

http-proxy-middleware is vulnerable to improper request routing. The vulnerability is due to unanchored substring matching in the host+path router selector logic, where configured host+path entries are matched against attacker-controlled request metadata using partial string comparisons instead o...

Astra Linux – Vulnerability in Firefox

The Remote Agent, used in WebDriver, did not validate the Host or Origin headers. This could have allowed websites to connect back locally to the user’s browser to control it. This bug only affected Firefox when WebDriver was enabled, which is not the default configuration.. This vulnerability...

Astra Linux – Vulnerability in Twisted

Twisted is an event-based framework for internet applications. It was introduced with version 0.9.4. At that time, when the host header did not match a configured host using twisted.web.vhost.NameVirtualHost, a “NoResource” resource would be returned. This caused the Host header to be rendered...

Astra Linux - Vulnerability in Golang-1.19

The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With this fix, the HTTP/1 client will now refuse to send requests that contain an invalid Request.Host or Request.URL.Host value...

Astra Linux – Vulnerability in python-webob

WebOb provides objects for HTTP requests and responses. When WebOb normalizes the HTTP Location header to include the request hostname, it does so by parsing the URL that the user will be redirected to using Python’s urlparse function, and joining that parsed URL to the base URL. However, the...

Astra Linux – Vulnerability in HAPProxy

A issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. This issue can lead to a situation where the HTTP Host header is controlled by an attacker, due to a mismatch between the Host field and its corresponding authority value being mishandled...

GHSA-4JGR-PG2M-M988 Heimdall: Forwarded Header Injection via Unsanitized Host Header in Proxy Mode

Summary When Heimdall operates in proxy mode, it constructs the Forwarded HTTP header after executing the matched rule pipeline by inserting the incoming request's Host header value directly into the header string without sanitizing commas or semicolons. This allows an attacker to inject addition...

GHSA-64MM-VXMG-Q3VJ http-proxy-middleware `router` host+path substring matching allows Host-header-driven backend routing bypass

Summary http-proxy-middleware documents router proxy-table entries as host, path, or host+path selectors, but the host+path implementation uses unanchored substring matching on attacker-controlled request metadata. As a result, a crafted Host header that is only a superstring match for a configur...
