Version Summary: Cisco TelePresence Collaboration Desk and Room Endpoints
running TC software contain a vulnerability that could allow an
unauthenticated, remote attacker to conduct cross-site scripting attacks.
Updates are available.
Description
A vulnerability within the login page of the web user interface of Cisco
TelePresence Collaboration Desk and Room Endpoints devices running TC Software
could allow an unauthenticated, remote attacker to conduct cross-site
scripting attacks.
The vulnerability is due to improper input validation of certain parameters
passed to an affected device. An unauthenticated, remote attacker could
exploit this vulnerability by convincing a user to follow a malicious link or
visit an attacker-controlled site. A successful exploit could allow the
attacker the ability to gain access to sensitive information or modify the
settings of the device.
Cisco has confirmed the vulnerability and released software updates.
Warning Indicators
Cisco TelePresence Collaboration Desk and Room Endpoints devices running TC
Software prior to version 7.1.0 are affected.
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a
user to a malicious site and use misleading language or instructions to
persuade the user to follow the link.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
Vendor Announcements
Cisco has released bug ID CSCuq94977 for registered users that contains
additional details and an up-to-date list of affected product versions.
Impact
An unauthenticated, remote attacker could exploit this vulnerability to
execute arbitrary script or HTML code in the user's browser session in the
context of the affected site. This could allow the attacker to access
sensitive browser-based information such as authentication cookies and
recently submitted data.
Technical Information
The vulnerability is due to insufficient validation of user-supplied input
passed to an affected device.
An unauthenticated, remote attacker could exploit this vulnerability by
convincing a user to follow a malicious link or visit an attacker-controlled
site. A successful exploit could allow the attacker the ability to execute
arbitrary script or HTML code in the user's browser session in the context of
the affected site, which could be leveraged to conduct further attacks.
Safeguards
Administrators are advised to apply the appropriate updates.
Users should verify that unsolicited links are safe to follow.
For additional information about XSS attacks and the methods used to exploit
these vulnerabilities, see the Cisco Applied Mitigation Bulletin Understanding
Cross-Site Scripting (XSS) Threat Vectors.
