CVE-2021-4199· NVD / CVE Program· CNA Bitdefender

Incorrect Permission Assignment for Critical Resource vulnerability in BDReinit.exe (VA-10017)

Noroxi assessment

Priority: Monitor (action score 31/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.75% (FIRST EPSS); higher than 54.7% of all records.
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
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.
