From the folly of stockpiling 0-day exploits to that of failing to apply security updates in a timely manner, it does seem with hindsight that much of the damage from WannaCry and NotPetya to who-knows-what-comes-next could have been largely avoided. A CVE number uniquely identifies one vulnerability from the list. In this post, we explain why and take a closer look at Eternalblue. To exploit the vulnerability, an unauthenticated attacker only has to send a maliciously-crafted packet to the server, which is precisely how WannaCry and NotPetya ransomware were able to propagate. BlueKeep (CVE-2019-0708) is a security vulnerability that was discovered in Microsoft's Remote Desktop Protocol (RDP) implementation, which allows for the possibility of remote code execution. | This query will identify if a machine has active SMB shares, is running an OS version impacted by this vulnerability, check to see if the disabled compression mitigating keys are set, and see if the system is patched.

On 12 September 2014, Stphane Chazelas informed Bash's maintainer Chet Ramey of his discovery of the original bug, which he called "Bashdoor". An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory, aka "Win32k Elevation of Privilege Vulnerability.". PAN-OS may be impacted by the Dirty COW (CVE-2016-5195) attack. Initial solutions for Shellshock do not completely resolve the vulnerability. Although a recent claim by the New York Times that Eternalblue was involved in the Baltimore attack seems wide of the mark, theres no doubt that the exploit is set to be a potent weapon for many years to come. This means that after the earlier distribution updates, no other updates have been required to cover all the six issues. The vulnerabilities, tracked as CVE-2021-44228 and CVE-2021-45046 and referred to as "Log4Shell," affects Java-based applications that use Log4j 2 versions 2.0 through 2.15.0. .
