Windows Media Center in Microsoft Windows Vista SP2, Windows 7 SP1, Windows 8, and Windows 8.1 allows remote attackers to read arbitrary fil
Noroxi assessment
Priority: Monitor (action score 31/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 46% (FIRST EPSS); higher than 98.7% of all records.
- According to the record, no fixed version is available yet.
Low priority for now. 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
Windows Media Center in Microsoft Windows Vista SP2, Windows 7 SP1, Windows 8, and Windows 8.1 allows remote attackers to read arbitrary files via a crafted .mcl file, aka "Windows Media Center Information Disclosure Vulnerability."
