Version Summary: Cisco Unified Communications Manager contains multiple
vulnerabilities that could allow an unauthenticated, remote attacker to
conduct cross-site scripting, cross-site request forgery, and phishing
attacks. Updates are available.
Description
Multiple vulnerabilities in Cisco Unified Communications Manager could allow
an unauthenticated, remote attacker to conduct cross-site scripting (XSS),
cross-site request forgery (XSRF), and phishing attacks on the affected
software.
The vulnerabilities are due to improper input validation of certain parameters
passed to the affected software. An attacker could exploit these
vulnerabilities by convincing a user to follow a malicious link. A successful
exploit could allow the attacker to execute arbitrary script code in the
context of the affected site or allow the attacker to access sensitive
browser-based information.
Cisco has confirmed these vulnerabilities and software updates are available.
Warning Indicators
At the time this alert was first published, Cisco Unified Communications
Manager 10.5(2.10000.5) was vulnerable. Later versions of Cisco Unified
Communications Manager may also be vulnerable.
IntelliShield Analysis
To exploit these vulnerabilities, 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.
Vendor Announcements
Cisco has released bug ID CSCut66725 for registered users, which contains
additional details and an up-to-date list of affected product versions.
Impact
An unauthenticated, remote attacker could exploit these vulnerabilities to
execute arbitrary script code in the context of the affected site or allow the
attacker to access sensitive browser-based information.
Technical Information
The vulnerabilities are due to improper input validation of certain parameters
passed to the affected software.
An attacker could exploit these vulnerabilities by convincing a user to follow
a malicious link. A successful exploit could allow the attacker to execute
arbitrary script code in the context of the affected site or allow the
attacker to access sensitive browser-based information.
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.
For additional information about CSRF attacks and potential mitigation
methods, see the Cisco Applied Mitigation Bulletin Understanding Cross-Site
Request Forgery Threat Vectors.
Administrators are advised to monitor affected systems.
