Version Summary: Cisco Unified Communications Manager contains a vulnerability
that could allow an unauthenticated, remote attacker to conduct cross-site
scripting attacks. Updates are available.
A vulnerability in several parameters of the ccmivr page of Cisco Unified
Communications Manager, formerly known as CallManager, could allow an
unauthenticated, remote attacker to conduct a cross-site scripting (XSS)
attack against a user of the web interface on an affected system.
The vulnerability is due to insufficient input validation of some parameters
used by the ccmivr page of the affected software. An attacker could exploit
this vulnerability by convincing the user of the system to follow an
attacker-supplied link. An exploit could allow the attacker to cause arbitrary
script or HTML to be executed on the user's browser within the context of the
Cisco has confirmed the vulnerability and released software updates.
At the time this alert was first published, Cisco Unified Communications
Manager release 10.5(2.10000.5) was vulnerable. Later releases of Cisco
Unified Communications Manager may also be vulnerable.
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 provided link.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
Cisco has released bug ID CSCut19580 for registered users, which contains
additional details and an up-to-date list of affected product versions.
An unauthenticated, remote attacker could exploit the vulnerability to execute
arbitrary script or HTML in the user's browser in the context of the affected
application, which could be used to access sensitive browser-based information
such as authentication cookies.
The vulnerability is due to insufficient input validation of certain
parameters used by the ccmivr page of the affected software.
An unauthenticated, remote attacker could exploit this vulnerability by
convincing the user of a targeted system to follow a malicious link. A
successful exploit could allow the attacker to execute arbitrary script or
HTML in the user's session, which could be used to access sensitive
browser-based information such as authentication cookies.
Administrators are advised to apply the appropriate updates.
Users should verify that unsolicited links are safe to follow.
Users are advised not to open email messages from suspicious or unrecognized
sources. If users cannot verify that links or attachments included in email
messages are safe, they are advised not to open them.
For additional information about cross-site scripting attacks and the methods
used to exploit these vulnerabilities, see the Cisco Applied Mitigation
Bulletin Understanding Cross-Site Scripting (XSS) Threat Vectors.
Administrators are advised to monitor affected systems.
