Summary
A vulnerability in the web interface for specific feature sets of
Cisco Integrated Management Controller (IMC) Supervisor and Cisco UCS
Director could allow an authenticated, remote attacker to access sensitive
information.
The vulnerability is due to an authorization check that does not properly
include the access level of the web interface user. An attacker who has
valid application credentials could exploit this vulnerability by sending a
crafted HTTP request to the web interface. A successful exploit could allow
the attacker to view sensitive information that belongs to other users. The
attacker could then use this information to conduct additional
reconnaissance attacks.
There are no workarounds that address this vulnerability.

Cisco Security Advisory
Cisco Integrated Management Controller Supervisor and Cisco UCS Director System
Resources Denial of Service Vulnerability
Priority: Medium
Advisory ID: cisco-sa-20181003-imcs-ucsd-dos
First Published: 2018 October 3 16:00 GMT
Version 1.0: Final

CVSS Score: Base 6.5
CVSS: 3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:X/RL:X/RC:X
Summary
A vulnerability in the web interface of Cisco Integrated Management
Controller (IMC) Supervisor and Cisco UCS Director could allow an
authenticated, remote attacker to cause a denial of service (DoS) condition
on an affected system.
The vulnerability is due to insufficient restrictions on the size or total
amount of resources allowed via the web interface. An attacker who has
valid credentials for the application could exploit this vulnerability by
sending a crafted or malformed HTTP request to the web interface. A
successful exploit could allow the attacker to cause oversubscription of
system resources or cause a component to become unresponsive, resulting in
a DoS condition.
There are no workarounds that address this vulnerability.
