Dell iDRAC6 / iDRAC7 / iDRAC8 Path Traversal Authentication Bypass

high Nessus Plugin ID 90265

Language:

Synopsis

The remote device is affected by a path traversal vulnerability that allows an authentication bypass.

Description

The remote Dell Remote Access Controller (iDRAC6 / iDRAC7 / iDRAC8) is affected by a path traversal vulnerability. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to bypass authentication and gain privileged access to the iDRAC controller.

Note that the application is also reportedly affected by several additional vulnerabilities, including a format string vulnerability, an SSH authentication issue with usernames larger than 62 characters, SSH shell buffer overflows, and an unspecified XML external entity (XXE) vulnerability; however, Nessus has not tested for these additional issues.

Solution

Upgrade to firmware version 2.80 (iDRAC6) / 2.21.21.21 (iDRAC7 and iDRAC8) or later.
