Three days have passed since Microsoft's latest Patch Tuesday, and CVE-2022-26809 has emerged as the vulnerability with the most exploitation potential. CVE-2022-26809 is a remote code execution vulnerability in Microsoft Remote Procedure Call runtime and affects a wide variety of Windows and Windows Server versions.
The embargo period is over for a proof-of-concept tool to test for the recently revealed BrakTooth flaws in Bluetooth devices, and the researchers who discovered them have released both the test kit and full exploit code for the bugs. BrakTooth is a collection of flaws affecting commercial Bluetooth stacks on more than 1,400 chipsets used in billions of devices - including smartphones, PCs, toys, internet-of-things devices and industrial equipment - that rely on Bluetooth Classic for communication.
New details have been revealed about a recently remediated critical vulnerability in Netgear smart switches that could be leveraged by an attacker to potentially execute malicious code and take control of vulnerable devices. The disclosure comes weeks after NETGEAR released patches to address the vulnerabilities earlier this month, on September 3.
Networking, storage and security solutions provider Netgear on Friday issued patches to address three security vulnerabilities affecting its smart switches that could be abused by an adversary to gain full control of a vulnerable device. The flaws, which were discovered and reported to Netgear by Google security engineer Gynvael Coldwind, impact the following models -.
Cisco has patched a critical security vulnerability impacting its Enterprise Network Function Virtualization Infrastructure Software that could be exploited by an attacker to take control of an affected system. The network equipment maker said it's aware of a publicly available proof-of-concept exploit code targeting the vulnerability, but added it's not detected any successful weaponization attempts in the wild.
A critical vulnerability that affects Cisco Enterprise NFV Infrastructure Software has been patched and Cisco is urging enterprise admins to quickly upgrade to a fixed version, as proof-of-concept exploit code is already available. The bug could be exploited by remote attackers to bypass authentication and log in to an affected device as an administrator.
Microsoft was quick to respond with a fix to an attack dubbed "PetitPotam" that could force remote Windows systems to reveal password hashes that could then be easily cracked. The PetitPotam PoC is a form of manipulator-in-the-middle attack against Microsoft's NTLM authentication system.
PoC for critical Windows Print Spooler flaw leakedMicrosoft has confirmed that the so-called PrintNightmare vulnerability is not the same flaw as the previously patched CVE-2021-1675, and that the leaked PoC exploits can be used to exploit this RCE zero-day. Cisco security devices targeted with CVE-2020-3580 PoC exploitAttackers and bug hunters are leveraging an exploit for CVE-2020-3580 to compromise vulnerable security devices running Cisco ASA or FTD software.
A proof-of-concept exploit related to a remote code execution vulnerability affecting Windows Print Spooler and patched by Microsoft earlier this month was briefly published online before being taken down. The Windows maker addressed the vulnerability as part of its Patch Tuesday update on June 8, 2021.
UPDATE. A proof-of-concept for a critical Windows security vulnerability that allows remote code execution was dropped on GitHub on Tuesday - and while it was taken back down within a few hours, the code was copied and is still out there circulating on the platform. The bug exists in the Windows Print Spooler and has been dubbed "PrintNightmare" by researchers.
