Security researchers have released a proof-of-concept exploit for a critical-severity vulnerability in Fortinet's FortiNAC network access control suite. Proof-of-concept exploit code is also available from the company's repository on GitHub.

Horizon3's Attack Team has released a PoC exploit for CVE-2022-39952, a critical vulnerability affecting FortiNAC, Fortinet's network access control solution. "Similar to the weaponization of previous archive vulnerability issues that allow arbitrary file write, we use this vulnerability to write a cron job to /etc/cron.d/payload. This cron job gets triggered every minute and initiates a reverse shell to the attacker," shared Zach Hanley, Chief Attack Engineer at Horizon3.

Cybersecurity solutions company Fortinet has released security updates for its FortiNAC and FortiWeb products, addressing two critical-severity vulnerabilities that may allow unauthenticated attackers to perform arbitrary code or command execution.FortiNAC is a network access control solution that helps organizations gain real-time network visibility, enforce security policies, and detect and mitigate threats.

Cisco has rolled out security updates to address a critical flaw reported in the ClamAV open source antivirus engine that could lead to remote code execution on susceptible devices."This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write," Cisco Talos said in an advisory.

We counted 75 CVE-numbered bugs dated 2023-02-14, given that this year's February updates arrived on Valentine's Day. We extracted a list and included it below, sorted so that the bugs dubbed Critical are at the top.

Horizon3 security researchers have released proof-of-concept code for a VMware vRealize Log Insight vulnerability chain that allows attackers to gain remote code execution on unpatched appliances. Earlier today, Horizon3 published the PoC exploit and explained that the RCE exploit "Abuses the various Thrift RPC endpoints to achieve an arbitrary file write."

How to tackle the cybersecurity skills shortage in the EUIn this Help Net Security Dritan Saliovski, Director - Nordic Head of Cyber M&A, Transaction Advisory Services at Aon, offers some pointers, as well as advice to organizations on how to attract and retain the best cybersecurity talent. ENISA gives out toolbox for creating security awareness programsThe European Union Agency for Cybersecurity has made available Awareness Raising in a Box, a "Do it yourself" toolbox to help organizations in their quest to create and implement a custom security awareness raising program.

Security researchers with Horizon3's Attack Team will release an exploit targeting a vulnerability chain next week for gaining remote code execution on unpatched VMware vRealize Log Insight appliances. Now known as VMware Aria Operations for Logs, vRealize Log Insight makes it easier for VMware admins to analyze and manage terabytes of infrastructure and application logs.

Lexmark has released a security firmware update to fix a severe vulnerability that could enable remote code execution on more than 100 printer models. "Lexmark is not aware of any malicious use against Lexmark products of the vulnerability described in this advisory, but proof of concept code has been publicly published" - Lexmark.

Over 19,000 end-of-life Cisco VPN routers on the Internet are exposed to attacks targeting a remote command execution exploit chain. By chaining two security flaws disclosed last week, threat actors can bypass authentication and execute arbitrary commands on the underlying operating system of Cisco Small Business RV016, RV042, RV042G, and RV082 routers.
