Advisory ID: cisco-sa-roomos-infodisc-YOTz9Ct7
First Published: 2022 July 6 16:00 GMT

Summary
o A vulnerability in the logging component of Cisco TelePresence
Collaboration Endpoint (CE) and RoomOS Software could allow an
authenticated, remote attacker to view sensitive information in clear text
on an affected system.
This vulnerability is due to the storage of certain unencrypted
credentials. An attacker could exploit this vulnerability by accessing the
audit logs on an affected system and obtaining credentials that they may
not normally have access to. A successful exploit could allow the attacker
to use those credentials to access confidential information, some of which
may contain personally identifiable information (PII).
Note: To access the logs that are stored in the RoomOS Cloud, an attacker
would need valid Administrator -level credentials.
Cisco has released software updates that address this vulnerability. There
are workarounds that address this vulnerability.
This advisory is available at the following link:

Affected Products
o Vulnerable Products
At the time of publication, this vulnerability affected Cisco devices if
they were running a vulnerable release of the following Cisco software and
had extended logging mode enabled:
TelePresence CE Software
RoomOS Software in Cloud-Aware On-Premises operation, which is cloud
based
Note: Extended logging mode is disabled by default. If it is enabled, a
full capture of network traffic will be included in the logs. PII will also
be included.
For information about which Cisco software releases were vulnerable at the
time of publication, see the Fixed Software section of this advisory. See
the Details section in the bug ID(s) at the top of this advisory for the
most complete and current information.
Determine Whether Extended Logging Mode is Enabled
To determine whether extended logging mode is enabled, complete the
following steps:
1. Choose the Cisco device name or address.
For all products except Board Pro, Desk Mini, and Desk Hub, it is
at the top of the interface.
For Board Pro and Desk Mini, swipe in from the right to open the
Control Panel.
For Desk Hub, tap the controls icon in the upper right corner to
open the Control Panel.
2. Choose Device settings (Board Pro, Desk Mini, or Desk Hub) or Settings
(other products).
3. Open Issues and diagnostics and check the extended logging toggle
button.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Workarounds
o There is a workaround that addresses this vulnerability. Administrators can
disable extended logging mode it by completing the following steps:
1. Choose the Cisco device name or address.
For all products except Board Pro, Desk Mini, and Desk Hub, it is
at the top of the interface.
For Board Pro and Desk Mini, swipe in from the right to open the
Control Panel.
For Desk Hub, tap the controls icon in the upper right corner to
open the Control Panel.
2. Choose Device settings (Board Pro, Desk Mini, or Desk Hub) or Settings
(other products).
3. Open Issues and diagnostics and find the extended logging toggle button
and turn it off .
While this workaround has proven successful in a test environment,
customers should determine the applicability and effectiveness in their own
environment and under their own use conditions. Customers should be aware
that any workaround or mitigation that is implemented may negatively impact
the functionality or performance of their network based on intrinsic
customer deployment scenarios and limitations. Customers should not deploy
any workarounds or mitigations before first evaluating the applicability to
their own environment and any impact to such environment.

o When considering software upgrades , customers are advised to regularly
consult the advisories for Cisco products, which are available from the
Cisco Security Advisories page , to determine exposure and a complete
upgrade solution.
In all cases, customers should ensure that the devices to be upgraded
contain sufficient memory and confirm that current hardware and software
configurations will continue to be supported properly by the new release.
If the information is not clear, customers are advised to contact the Cisco
Technical Assistance Center (TAC) or their contracted maintenance
providers.
