Dell iDRAC
CVE-2019-3705
Dell EMC iDRAC6 versions prior to 2.92, iDRAC7/iDRAC8 versions prior to 2.61.60.60, and iDRAC9 versions prior to 3.20.21.20, 3.21.24.22, 3.21.26.22 and 3.23.23.23 contain a stack-based buffer overflow vulnerability. An unauthenticated remote attacker may potentially exploit this vulnerability to crash the webserver or execute arbitrary code on the system with privileges of the webserver by sending specially crafted input data to the affected system.
Affected versions (NVD)
| Product | Versions |
|---|---|
| idrac6_firmware | < 2.92 |
| idrac7_firmware | < 2.61.60.60 |
| idrac8_firmware | < 2.61.60.60 |
| idrac9_firmware | < 3.20.21.20 |
What to do
NVD marks firmware before these versions as affected: idrac6_firmware before 2.92; idrac7_firmware before 2.61.60.60; idrac8_firmware before 2.61.60.60; idrac9_firmware before 3.20.21.20. The usual fix is to update to that version or later. Vendors patch each firmware branch separately, so confirm the fixed build for your branch in the advisory.
