- Date Discovered:
- 10 July 2018
- Microsoft Windows PowerShell is prone to a remote code-execution vulnerability. Successfully exploiting this issue may result in the execution of arbitrary code in the context of the affected process. Failed exploit attempts will likely result in denial-of-service conditions.
- Microsoft PowerShell Editor Services
- Microsoft PowerShell Extension for Visual Studio Code
Run all software as a nonprivileged user with minimal access rights.To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits
Do not follow links provided by unknown or untrusted sources.Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Implement multiple redundant layers of security.Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.
