CVSS 2 Score 
10
Impacted Systems 
Apache Struts
Description 
The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 has incorrect exception handling and error-message generation during file-upload attempts, which allows remote attackers to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header, as exploited in the wild in March 2017 with a Content-Type header containing a #cmd= string.
Impact 
  • A remote user can execute arbitrary operating system commands on the target system.
Threat Actor

4. CVE-2017-5715 - Also known as Spectre
CVSS 2 Score 
4.7
Impacted Systems 
ARM, Intel
Description: 
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
Impact:  
A local user can run specially crafted code to cause the CPU to speculatively execute an indirect branch to leak memory contents from another process into a CPU cache and then read the contents of the cache [CVE-2017-5715]. A local user can view arbitrary virtual memory contents on the target CPU device [which can lead to elevated privileges on the target system]
Threat Actor 
Unknown

5
Impacted Systems 
Oracle WebLogic Server
Description 
A remote user can exploit a flaw in the Oracle WebLogic Server WLS Security component to gain elevated privileges.
Impact 
  • A remote authenticated user can obtain data on the target system.
  • A remote user can modify data on the target system.
  • A remote user can cause denial of service conditions
Threat Actor
