Juniper Networks has patched critical-rated bugs across its Junos Space, Contrail Networking and NorthStar Controller products that are serious enough to prompt CISA to weigh in and advise admins to update the software as soon as possible. "CISA encourages users and administrators to review the Juniper Networks security advisories page and apply the necessary updates," according to the Feds' warning this week.
CISA has added an actively exploited local privilege escalation vulnerability in the Windows Client/Server Runtime Subsystem to its list of bugs abused in the wild.This high severity security flaw impacts both server and client Windows platforms, including the latest Windows 11 and Windows Server 2022 releases.
NPower, a US-based non-profit participating in a cybersecurity workforce development program started by the Cybersecurity and Infrastructure Agency, is looking for recruits for a free cybersecurity training program aimed at underserved populations in the US, including women, people of color, young adults, and military veterans and their spouses. We've asked Nelson Abbott, Senior Director of Advanced Program Operations at NPower, and Chris Starling, a US Marine Corps veteran and Assistant VP at NPower California, to tell us more about it.
CISA has re-added a security bug affecting Windows devices to its list of bugs exploited in the wild after removing it in May due to Active Directory certificate authentication issues caused by Microsoft's May 2022 updates. The flaw is an actively exploited Windows LSA spoofing vulnerability tracked as CVE-2022-26925 and confirmed to be a new PetitPotam Windows NTLM Relay attack vector.
The U.S. Cybersecurity and Infrastructure Security Agency this week moved to add a Linux vulnerability dubbed PwnKit to its Known Exploited Vulnerabilities Catalog, citing evidence of active exploitation. Polkit is a toolkit for controlling system-wide privileges in Unix-like operating systems, and provides a mechanism for non-privileged processes to communicate with privileged processes.
The Cybersecurity and Infrastructure Security Agency has added a high-severity Linux vulnerability known as PwnKit to its list of bugs exploited in the wild. PwnKit is a memory corruption bug that unprivileged users can exploit to gain full root privileges on Linux systems with default configurations.
CISA has urged government agencies and private sector organizations using Microsoft's Exchange cloud email platform to expedite the switch from Basic Authentication legacy authentication methods without multifactor authentication support to Modern Authentication alternatives. Basic Auth is an HTTP-based auth scheme used by apps to send credentials in plain text to servers, endpoints, or online services.
If your organization is running VMware Horizon and Unified Access Gateway servers and you haven't implemented the patches or workarounds to fix/mitigate the Log4Shell vulnerability in December 2021, you should threat all those systems as compromised, the Cybersecurity and Infrastructure Security Agency has advised on Thursday. According to the CISA, cyber threat actors, including state-sponsored advanced persistent threat actors, have continued to exploit Log4Shell in unpatched, internet-facing VMware Horizon and Unified Access Gateway servers to obtain initial access to organizations.
CISA warned today that threat actors, including state-backed hacking groups, are still targeting VMware Horizon and Unified Access Gateway servers using the Log4Shell remote code execution vulnerability. Attackers can exploit Log4Shell remotely on vulnerable servers exposed to local or Internet access to move laterally across networks until they gain access to internal systems containing sensitive data.
Fifty-six vulnerabilities - some deemed critical - have been found in industrial operational technology systems from ten global manufacturers including Honeywell, Ericsson, Motorola, and Siemens, putting more than 30,000 devices worldwide at risk, according to the US government's CISA and private security researchers. Forescout's Vedere Labs discovered the bugs in devices built by ten vendors in use across the security company's customer base, and collectively named them OT:ICEFALL. According to the researchers, the vulnerabilities affect at least 324 organizations globally - and in reality this number is probably much larger since Forescout only has visibility into its own customers' OT devices.
