Fortinet FortiGate CVE-2024-23113 - A Super Complex Vulnerability In A Super Secure Appliance In 2024
Fortinet FortiGate CVE-2024-23113 - A Super Complex Vulnerability In A Super Secure Appliance In 2024
It affected (before patching) all currently-maintained branches, and recently was highlighted by CISA as being exploited-in-the-wild. This must be the first time real-world attackers have reversed a patch, and reproduced a vulnerability, before some dastardly researchers released a detection artefact generator tool of their own. /s At watchTowr's core, we're all about identifying and validating ways into organisations - sometimes through vulnerabilities in network border appliances - without requiring such luxuries as credentials or asset lists.
