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). For additional details on OpenShift

Weak session management in DB Elettronica Telecomunicazioni SpA SFT DAB 600/C Firmware: 1.9.3 Bios firmware: 7.1 (Apr 19 2021) Gui: 2.46 FPGA: 169.55 uc: 6.15 allows attackers on the same network to bypass authentication by re-using the IP address assigned to the device by the NAT protocol.

A buffer overflow vulnerability in the SecureBootDXE BIOS driver of some Lenovo Desktop and ThinkStation models could allow an attacker with local access to elevate their privileges to execute arbitrary code.

Cybersecurity researchers have found "backdoor-like behavior" within Gigabyte systems, which they say enables the UEFI firmware of the devices to drop a Windows executable and retrieve updates in an unsecure format. Firmware security firm Eclypsium said it first detected the anomaly in April 2023. Gigabyte has since acknowledged and addressed the issue. "Most Gigabyte firmware includes a Windows

Dell VxRail versions earlier than 7.0.450, contain(s) an OS command injection vulnerability in VxRail Manager. A local authenticated attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying OS, with the privileges of the vulnerable application. Exploitation may lead to a system take over by an attacker.

Suprema BioStar 2 before 2022 Q4, v2.9.1 has Insecure Permissions. A vulnerability in the web application allows an authenticated attacker with "User Operator" privileges to create a highly privileged user account. The vulnerability is caused by missing server-side validation, which can be exploited to gain full administrator privileges on the system.

Dell PowerEdge 14G server BIOS versions prior to 2.18.1 and Dell Precision BIOS versions prior to 2.18.2, contain an Out of Bounds write vulnerability. A local attacker with low privileges could potentially exploit this vulnerability leading to exposure of some SMRAM stack/data/code in System Management Mode, leading to arbitrary code execution or escalation of privilege.
