This Tech Tip outlines the steps enterprise defenders should take as they protect their data in cloud environments in response to the security incident with the CI/CD platform.

## Summary RSSHub is vulnerable to Server-Side Request Forgery (SSRF) attacks. This vulnerability allows an attacker to send arbitrary HTTP requests from the server to other servers or resources on the network. ## Description An attacker can exploit this vulnerability by sending a request to the affected routes with a malicious URL. For example, if an attacker controls the `ATTACKER.HOST` domain, they can send a request to affected routes with the value set to `ATTACKER.HOST%2F%23`. The `%2F` and `%23` characters are URL-encoded versions of the forward-slash (`/`) and pound (`#`) characters, respectively. In this context, an attacker could use those characters to append the base URL (i.e. `https://${input}.defined.host`) to be modified to `https://ATTACKER.HOST/#.defined.host`. This will cause the server to send a request to the attacker-controlled domain, allowing the attacker to potentially gain access to sensitive information or perform further attacks on the server. ## Proof o...

Cargo is a Rust package manager. The Rust Security Response WG was notified that Cargo did not perform SSH host key verification when cloning indexes and dependencies via SSH. An attacker could exploit this to perform man-in-the-middle (MITM) attacks. This vulnerability has been assigned CVE-2022-46176. All Rust versions containing Cargo before 1.66.1 are vulnerable. Note that even if you don't explicitly use SSH for alternate registry indexes or crate dependencies, you might be affected by this vulnerability if you have configured git to replace HTTPS connections to GitHub with SSH (through git's [`url.<base>.insteadOf`][1] setting), as that'd cause you to clone the crates.io index through SSH. Rust 1.66.1 will ensure Cargo checks the SSH host key and abort the connection if the server's public key is not already trusted. We recommend everyone to upgrade as soon as possible.

Updated RHV packages that fix several bugs and add various enhancements are now available. Red Hat Product Security has rated this update as having a security impact of Important.

The Rust Security Response WG was notified that Cargo did not perform SSH host key verification when cloning indexes and dependencies via SSH. An attacker could exploit this to perform man-in-the-middle (MITM) attacks. This vulnerability has been assigned CVE-2022-46176. ## Overview When an SSH client establishes communication with a server, to prevent MITM attacks the client should check whether it already communicated with that server in the past and what the server's public key was back then. If the key changed since the last connection, the connection must be aborted as a MITM attack is likely taking place. It was discovered that Cargo never implemented such checks, and performed no validation on the server's public key, leaving Cargo users vulnerable to MITM attacks. ## Affected Versions All Rust versions containing Cargo before 1.66.1 are vulnerable. Note that even if you don't explicitly use SSH for alternate registry indexes or crate dependencies, you might be affected b...
