Dell EMC IdentifierDSA-2020-191
CVE Identifier:CVE-2020-5366


Severity Rating:CVSSv3 Base Score: 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L)
Affected Products:RSA NetWitness Logs & Network, hardware appliance deployments only
Summary:Dell EMC iDRAC has been updated to address a vulnerability that may be exploited to compromise the affected systems.
  • Improper Limitation of a Pathname to a Restricted Directory ("Path Traversal")

Dell EMC iDRAC9 versions prior to contain a Path Traversal Vulnerability. A remote authenticated malicious user with low privileges could potentially exploit this vulnerability by manipulating input parameters to gain unauthorized read access to the arbitrary files.


The following Dell EMC iDRAC firmware releases contain resolutions to these vulnerabilities:

  • iDRAC9

Customers can obtain the firmware upgrade instructions via the following link:


RSA recommends all customers upgrade at the earliest opportunity.

Dell EMC Best Practices regarding iDRAC:

  • The iDRAC is intended to be on a separate management network. The iDRAC is not designed nor intended to be placed on, nor connected directly to the Internet. Doing so could expose the connected system to security and other risks for which Dell EMC is not responsible.
  • Dell EMC recommends using the Dedicated Gigabit Ethernet port available on rack and tower servers to connect the iDRAC to a separate management network.
  • Along with locating iDRAC on a separate management network, users should isolate the management subnet/vLAN with technologies such as firewalls, and limit access to the subnet/vLAN to authorized server administrators.
  • Dell EMC recommends using 256-bit encryption strength as well as TLS 1.2 or higher. For tighter control, additional ciphers may be removed via "Cipher Select" – see the iDRAC User Guide for more details.
  • Dell EMC recommends additional settings such as IP range filtering and System Lockdown Mode.
  • Dell EMC recommends using additional security authentication options such as Microsoft Active Directory or LDAP.
  • Dell EMC recommends keeping iDRAC firmware up to date.
