CVE-2019-17596

CVE-2019-17596 is a vulnerability that was discovered in 2019. It is a flaw that affects the VPN software developed by Fortinet, which is widely used by businesses and organizations for secure remote access to their networks. The vulnerability allows an attacker with limited access to the target network to execute arbitrary code and gain full control over the affected system. When the vulnerability was first discovered, Fortinet released a patch to address the issue. However, it soon became clear that many organizations had not applied the patch, leaving them vulnerable to attack. In December 2019, the US National Security Agency (NSA) issued an advisory warning about the vulnerability, highlighting its potential impact and urging organizations to take immediate action to apply the patch. Despite these warnings, the vulnerability continued to be exploited by cybercriminals. In April 2021, the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) issued a joint alert, warning of ongoing attacks targeting Fortinet VPNs. The alert urged organizations to apply the patch and implement other security measures to protect against the vulnerability. As of now, organizations are advised to ensure that their Fortinet VPN software is up-to-date and to follow best practices for securing remote access to their networks.
