CVE-2021-36347
Status: ModifiedHigh (7.2)—
iDRAC9 versions prior to 5.00.20.00 and iDRAC8 versions prior to 2.82.82.82 contain a stack-based buffer overflow vulnerability. An authenticated remote attacker with high privileges could potentially exploit this vulnerability to control process execution and gain access to the iDRAC operating system.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
- Base score: 7.2
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.21%
- Percentile among all scored CVEs: 82
- Score date: 10/5/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
