Versions of the package sinatra from 0.0.0 are vulnerable to Reliance on Untrusted Inputs in a Security Decision via the X-Forwarded-Host (XFH) header. When making a request to a method with redirect applied, it is possible to trigger an Open Redirect Attack by inserting an arbitrary address into this header. If used for caching purposes, such as with servers like Nginx, or as a reverse proxy, without handling the X-Forwarded-Host header, attackers can potentially exploit Cache Poisoning or Routing-based SSRF.

### Impact When a user disables two-factor authentication via the Panel, a `DELETE` request with their current password in a query parameter will be sent. While query parameters are encrypted when using TLS, many webservers (including ones officially documented for use with Pterodactyl) will log query parameters in plain-text, storing a user's password in plain text. If a malicious user obtains access to these logs they could *potentially* authenticate against a user's account; assuming they are able to discover the account's email address or username **separately**. ### Patches This problem has been patched by <https://github.com/pterodactyl/panel/commit/8be2b892c3940bdc0157ccdab16685a72d105dd1> on the `1.0-develop` branch and released under `v1.11.8` as a single commit on top of `v1.11.7` <https://github.com/pterodactyl/panel/commit/75b59080e2812ced677dab516222b2a3bb34e3a4> Patch file: <https://github.com/pterodactyl/panel/commit/8be2b892c3940bdc0157ccdab16685a72d105dd1.patch> ...

# Description ## Path traversal This vulnerability allows an attacker to craft a request which is able to traverse the server file system and retrieve the contents of arbitrary files, including sensitive data such as configuration files, environment variables, and other critical data stored on the server. From Rajesh Sharma who discovered the vulnerability: POC: `curl --path-as-is http://localhost:3000/assets/../package.json` gives you the content of package.json present in the local directory. The vulnerability stems from usage of decodedReqPath directly in path.join without performing any path normalization i.e path.normalize in node.js https://github.com/vendure-ecommerce/vendure/blob/801980e8f599c28c5059657a9d85dd03e3827992/packages/asset-server-plugin/src/plugin.ts#L352-L358 If the vendure service is behind some server like nginx, apache, etc. Path normalization is performed on the root server level but still the actual client's request path will be sent to vendure service ...

Ubuntu Security Notice 7014-3 - USN-7014-1 fixed a vulnerability in nginx. This update provides the corresponding update for Ubuntu 14.04 LTS. It was discovered that the nginx ngx_http_mp4 module incorrectly handled certain malformed mp4 files. In environments where the mp4 directive is in use, a remote attacker could possibly use this issue to cause nginx to crash, resulting in a denial of service.

Ubuntu Security Notice 7014-2 - USN-7014-1 fixed a vulnerability in nginx. This update provides the corresponding updates for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. It was discovered that the nginx ngx_http_mp4 module incorrectly handled certain malformed mp4 files. In environments where the mp4 directive is in use, a remote attacker could possibly use this issue to cause nginx to crash, resulting in a denial of service.

Gentoo Linux Security Advisory 202409-32 - Multiple vulnerabilities have been discovered in nginx, the worst of which could result in denial of service. Versions greater than or equal to 1.26.2-r2 are affected.

### Impact Clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users trusting headers set by their proxy may be affected. Attackers may be able to downgrade connections to HTTP (non-SSL) or redirect responses, which could cause confidentiality leaks if combined with a separate MITM attack. ### Patches v6.4.3/v5.6.9 now discards any headers using underscores if the non-underscore version also exists. Effectively, allowing the proxy defined headers to always win. ### Workarounds Nginx has a [underscores_in_headers](https://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers) configuration variable to discard these headers at the proxy level. Any users that are implicitly trusting the proxy defined headers for security or availability should immediately cease doing so until upgraded to the fixed versions.

For modern applications built on Kubernetes and microservices, platform engineering is not just about building functional systems but also about embedding security into the fabric of those systems.
