Microsoft warned today that ransomware gangs are actively exploiting a VMware ESXi authentication bypass vulnerability in attacks. Ransomware groups have focused on creating lockers dedicated to encrypting ESXi VMs rather than targeting specific ESXi vulnerabilities that would provide them a quicker way of acquiring and maintaining access to a victim's hypervisors.

Hundreds of UEFI products from 10 vendors are susceptible to compromise due to a critical firmware supply-chain issue known as PKfail, which allows attackers to bypass Secure Boot and install malware. As the Binarly Research Team found, affected devices use a test Secure Boot "Master key"-also known as Platform Key-generated by American Megatrends International, which was tagged as "DO NOT TRUST" and that upstream vendors should've replaced with their own securely generated keys.

A critical-severity Docker Engine vulnerability may be exploited by attackers to bypass authorization plugins via specially crafted API request, allowing them to perform unauthorized actions, including privilege escalation. "An attacker could exploit a bypass using an API request with Content-Length set to 0, causing the Docker daemon to forward the request without the body to the AuthZ plugin, which might approve the request incorrectly," Docker Senior Security Engineer Gabriela Georgieva explained.

Docker is warning of a critical flaw impacting certain versions of Docker Engine that could allow an attacker to sidestep authorization plugins under specific circumstances. "An attacker could exploit a bypass using an API request with Content-Length set to 0, causing the Docker daemon to forward the request without the body to the AuthZ plugin, which might approve the request incorrectly," the Moby Project maintainers said in an advisory.

Netgear warned customers to update their devices to the latest available firmware, which patches stored cross-site scripting and authentication bypass vulnerabilities in several WiFi 6 router models. The stored XSS security flaw impacts the XR1000 Nighthawk gaming router.

Juniper Networks has released an emergency update to address a maximum severity vulnerability that leads to authentication bypass in Session Smart Router, Session Smart Conductor, and WAN Assurance Router products. "An Authentication Bypass Using an Alternate Path or Channel vulnerability in Juniper Networks Session Smart Router or Conductor running with a redundant peer allows a network-based attacker to bypass authentication and take full control of the device," reads the description of the vulnerability.

Open-source Rafel RAT steals info, locks Android devices, asks for ransomThe open-source Rafel RAT is being leveraged by multiple threat actors to compromise Android devices and, in some cases, to lock them, encrypt their contents, and demand money to restore the device to its original state. Future trends in cyber warfare: Predictions for AI integration and space-based operationsIn this Help Net Security interview, Morgan Wright, Chief Security Advisor at SentinelOne, discusses how AI is utilized in modern cyber warfare by state and non-state actors.

Threat actors are already trying to exploit a critical authentication bypass flaw in Progress MOVEit Transfer, less than a day after the vendor disclosed it. MOVEit Transfer is a managed file transfer solution used in enterprise environments to securely transfer files between business partners and customers using the SFTP, SCP, and HTTP protocols.

A novel Android attack vector from a piece of malware tracked as Snowblind is abusing a security feature to bypass existing anti-tampering protections in apps that handle sensitive user data. [...]
