Unpatched zero-day flaws have led to a spike in cyberattacks and a majority of these is attributed to a critical zero-day authentication bypass vulnerability discovered in the Pulse Secure Connect gateway. The flaw has been used as a part of the initial infection vector to distribute 12 malware families across multiple government and law enforcement agencies.
Moreover, exploitation of three zero-day vulnerabilities affecting SonicWall ES/Hosted Email Security has also come to the light. Users are advised to apply security patches to stay safe from these attacks.
Amid these threats, major security updates that compromise fixes for around 390 flaws have been announced by Oracle. Around 200 of these flaws can be exploited remotely without authentication.
