Noroxi assessment
Priority: Plan (action score 45/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 27.3% (FIRST EPSS); higher than 98% of all records.
- According to the record, no fixed version is available yet.
Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
UsbCharger.dll in the Energizer DUO USB battery charger software contains a backdoor that is implemented through the Arucer.dll file in the %WINDIR%\system32 directory, which allows remote attackers to download arbitrary programs onto a Windows PC, and execute these programs, via a request to TCP port 7777.
