The Ivanti vulnerability timeline reveals that multiple critical vulnerabilities were discovered in the software products Ivanti Connect Secure and Ivanti Policy Secure, with at least 30,000 instances of these products across the internet creating a significant opportunity for threat actors to exploit them. The US Cybersecurity and Infrastructure Security Agency (CISA) has mandated that federal agencies disconnect all Ivanti VPN appliances by February 2, 2024, due to the high risk of exploitation and potential impact. This unprecedented move highlights the severity of the issue and emphasizes the need for organizations across various industries to take immediate action to patch these vulnerabilities and protect themselves against potential attacks.
