Version Summary:Cisco Unified Communications management products contain a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks on a targeted system. Updates are not available.
 
 
Description
A vulnerability in the web framework of Cisco unified communications management products could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface on the affected system.

The vulnerability is due to insufficient input validation of a parameter. An attacker could exploit this vulnerability by convincing a user to access a malicious link.

Cisco has confirmed the vulnerability in a security bug report. However, software updates are not available.
 
Warning Indicators
The following Cisco Unified Communications management products are vulnerable:
  • Cisco Unified Operations Manager 8.6 and prior.
  • Cisco Unified Service Monitor 8.6 and prior.
 
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 in an attempt to persuade the user to follow the malicious link.
 
Vendor Announcements
Cisco has released a security notice for bug IDs CSCuh47574 and CSCuh95997 at the following link: CVE-2013-3416
 
Impact
An unauthenticated, remote attacker could exploit the vulnerability to execute arbitrary HTML or script code in the user's browser session in the security context of the affected site. An exploit  could allow the attacker to obtain sensitive information such as authentication cookies or recently submitted data.
 
Technical Information
The web framework component of the affected software fails to perform sufficient validation of user-supplied input to certain parameters when processing crafted URLs.

An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to follow a crafted URL that is designed to submit malicious input to the vulnerable script. If successful, the attacker could  access sensitive browser-based information or execute actions on the site with the privileges of the user.

Further technical information is not available.
 
Safeguards
Administrators are advised to contact the vendor regarding future updates and releases.

Users should verify that unsolicited links are safe to follow.

Users are advised not to visit websites or follow links that have suspicious characteristics or cannot be verified as safe.

For additional information about cross-site scripting attacks and potential methods of mitigation, see the Cisco Applied Mitigation Bulletin Understanding Cross-Site Scripting (XSS) Threat Vectors.

Administrators are advised to monitor affected systems.
