Germany-based cybersecurity company Genua has fast-tracked a fix for a critical flaw in one of its firewall products. Affected by the critical flaws is the GenuGate High Resistance Firewall, which Genua touts as a two-tier firewall that includes an application-level gateway and a packet filter for blocking malicious data.
A critical, easy to exploit vulnerability may allow attackers to remotely connect to a number of Rockwell Automation's programmable logic controllers and to install new firmware, alter the device's configuration, and so on. Rockwell Automation's PLCs are used around the world to control industrial equipment.
Cisco has addressed a maximum severity vulnerability in its Application Centric Infrastructure Multi-Site Orchestrator that could allow an unauthenticated, remote attacker to bypass authentication on vulnerable devices. Separately, the company also patched multiple flaws in Cisco Application Services Engine that could grant a remote attacker to access a privileged service or specific APIs, resulting in capabilities to run containers or invoke host-level operations, and learn "Device-specific information, create tech support files in an isolated volume, and make limited configuration changes."
Project Zero, Google's 0day bug-hunting team, shared technical details and proof-of-concept exploit code for a critical remote code execution bug affecting a Windows graphics component. The Project Zero researchers discovered the vulnerability, tracked as CVE-2021-24093, in a high-quality text rendering Windows API named Microsoft DirectWrite.
A critical vulnerability in Cisco Systems' intersite policy manager software could allow a remote attacker to bypass authentication. The flaw stems from improper token validation on an API endpoint in Cisco's ACI MSO. "A successful exploit could allow the attacker to receive a token with administrator-level privileges that could be used to authenticate to the API on affected MSO and managed Cisco Application Policy Infrastructure Controller devices," said Cisco on Wednesday.
Just one day after VMware announced the availability of patches for a critical vulnerability affecting vCenter Server, hackers have started scanning the internet for vulnerable servers. The flaw, tracked as CVE-2021-21972, affects the vSphere Client component of vCenter Server and it can be exploited by a remote, unauthenticated attacker to execute arbitrary commands with elevated privileges on the operating system that hosts vCenter Server.
The day after VMware released fixes for a critical RCE flaw found in a default vCenter Server plugin, opportunistic attackers began searching for publicly accessible vulnerable systems. We've detected mass scanning activity targeting vulnerable VMware vCenter servers.
In 2020 attackers were observed pivoting their attacks to businesses for which global COVID-19 response efforts heavily relied, such as hospitals, medical and pharmaceutical manufacturers, as well as energy companies powering the COVID-19 supply chain. "In essence, the pandemic reshaped what is considered critical infrastructure today, and attackers took note. Many organizations were pushed to the front lines of response efforts for the first time - whether to support COVID-19 research, uphold vaccine and food supply chains, or produce personal protective equipment," said Nick Rossmann, Global Threat Intelligence Lead, IBM Security X-Force.
VMware has patched three vulnerabilities in its virtual-machine infrastructure for data centers, the most serious of which is a remote code execution flaw in its vCenter Server management platform. The researcher found the most critical of the flaws, which is being tracked as CVE-2021-21972 and has a CVSS v3 score of 9.8, in a vCenter Server plugin for vROPs in the vSphere Client functionality, according to an advisory posted online Tuesday by VMware.
VMware on Tuesday informed customers that its vCenter Server product is affected by a critical vulnerability that can be exploited by an attacker to execute commands with elevated privileges. vCenter Server is a management software designed to provide a centralized platform for controlling VMware vSphere environments.
