Cross-site Scripting occurrences in Unified Contact Center Express
A vulnerability in the web-based management interface of Cisco Unified Intelligence Center could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information. (2021-06-16, CVE-2021-1395)
A vulnerability in the web-based management interface of Cisco Unified Intelligence Center Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. (2021-04-08, CVE-2021-1463)
A vulnerability in the web-based management interface of Cisco Finesse could allow an unauthenticated, remote attacker to bypass authorization and access sensitive information related to the device. The vulnerability exists because the software fails to sanitize URLs before it handles requests. An attacker could exploit this vulnerability by submitting a crafted URL. A successful exploit could allow the attacker to gain unauthorized access to sensitive information. (2020-01-26, CVE-2019-15278)
A vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker needs valid administrator credentials. (2019-08-21, CVE-2019-12626)
Multiple vulnerabilities in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. Cisco Bug IDs: CSCvg70904. (2018-07-18, CVE-2018-0400)
Multiple vulnerabilities in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. Cisco Bug IDs: CSCvg70967. (2018-07-18, CVE-2018-0401)
Why Cross-site Scripting can be dangerous
Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.
The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:
https://server.com/confirmation?message=Transaction+Complete
what results in:
<span>Confirmation: Transaction Complete</span>
In that case the message can be modified to become a valid Javascript code, e.g.:
https://server.com/confirmation?message=<script>dangerous javascript code here</script>
and it will be executed locally by the user's browser with full access to the user's personal application/browser data:
<span>Confirmation: <script>dangerous javascript code here</script></span>
