A group of researchers has revealed what it says is a vulnerability in a specific implementation of CRYSTALS-Kyber, one of the encryption algorithms chosen by the U.S. government as quantum-resistant last year. The exploit relates to "side-channel attacks on up to the fifth-order masked implementations of CRYSTALS-Kyber in ARM Cortex-M4 CPU," Elena Dubrova, Kalle Ngo, and Joel Gärtner of KTH

KioWare through 8.33 on Windows sets KioScriptingUrlACL.AclActions.AllowHigh for the about:blank origin, which allows attackers to obtain SYSTEM access via KioUtils.Execute in JavaScript code.

### Summary Directus versions <=9.22.4 is vulnerable to Server-Side Request Forgery (SSRF) when importing a file from a remote web server (POST to `/files/import`). An attacker can bypass the security controls that were implemented to patch vulnerability [CVE-2022-23080](https://security.snyk.io/vuln/SNYK-JS-DIRECTUS-2934713) by performing a [DNS rebinding attack](https://en.wikipedia.org/wiki/DNS_rebinding) and view sensitive data from internal servers or perform a local port scan (eg. can access internal metadata API for AWS at `http://169.254.169.254` event if `169.254.169.254` is in the deny IP list). ### Details DNS rebinding attacks work by running a DNS name server that resolves two different IP addresses when a domain is resolved simultaneously. This type of attack can be exploited to bypass the IP address deny list validation that was added to [`/api/src/services/file.ts`](https://github.com/directus/directus/blob/main/api/src/services/files.ts) for the function `importOne` t...

Directus is a real-time API and App dashboard for managing SQL database content. Directus is vulnerable to Server-Side Request Forgery (SSRF) when importing a file from a remote web server (POST to `/files/import`). An attacker can bypass the security controls by performing a DNS rebinding attack and view sensitive data from internal servers or perform a local port scan. An attacker can exploit this vulnerability to access highly sensitive internal server(s) and steal sensitive information. This issue was fixed in version 9.23.0.

A vulnerability in the nginx configurations that are provided as part of the VPN-less reverse proxy for Cisco Finesse could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition for new and existing users who are connected through a load balancer. This vulnerability is due to improper IP address filtering by the reverse proxy. An attacker could exploit this vulnerability by sending a series of unauthenticated requests to the reverse proxy. A successful exploit could allow the attacker to cause all current traffic and subsequent requests to the reverse proxy through a load balancer to be dropped, resulting in a DoS condition.

The Biden administration today issued its vision for beefing up the nation's collective cybersecurity posture, including calls for legislation establishing liability for software products and services that are sold with little regard for security. The White House's new national cybersecurity strategy also envisions a more active role by cloud providers and the U.S. military in disrupting cybercriminal infrastructure, and names China as the single biggest cyber threat to U.S. interests.

A code injection vulnerability was identified in GitHub Enterprise Server that allowed setting arbitrary environment variables from a single environment variable value in GitHub Actions when using a Windows based runner. To exploit this vulnerability, an attacker would need existing permission to control the value of environment variables for use with GitHub Actions. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.8.0 and was fixed in versions 3.4.15, 3.5.12, 3.6.8, 3.7.5. This vulnerability was reported via the GitHub Bug Bounty program.

Overcoming the obstacles of this security principle can mitigate the damages of an attack.
