Cisco Unified Communications Domain Manager contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks on a targeted system. Updates are available.
Cisco Unified Communications Domain Manager contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks.
The vulnerability exists because the web framework component of the affected software fails to perform sufficient validation and sanitation of user-supplied input when processing crafted URLs. An unauthenticated, remote attacker could exploit the vulnerability 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 and allow the attacker to access sensitive browser-based information.
Cisco has confirmed the vulnerability in a security notice and has released software updates.
At the time this alert was first published, Cisco Unified Communications Domain Manager versions 8.6, 8.6.2, 9.0, and 9.0.1 were vulnerable. Later versions of Cisco Unified Communications Domain Manager may also be affected.
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 a user to follow the malicious link.
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary script or HTML code in the user's browser in the security context of the affected application. This action could allow the attacker to steal sensitive browser-based information, including authentication cookies and recently submitted data, or to take actions on the site as the affected user.
The web framework component of the affected software fails to perform sufficient validation and sanitation of user-supplied input to certain parameters when processing crafted URLs before returning the input to the user's browser session. When returned to the browser, the malicious parameters may execute in the security context of the affected site.
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. The script may return that input to the user's browser without proper sanitation and render the input in the security context of the affected site. The attacker could include arbitrary script or HTML code that could allow the attacker to access sensitive browser-based information or execute actions on the site with the privileges of the user.
Administrators are advised to apply the appropriate updates.
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.
Administrators are advised to monitor affected systems.
