Servicenow Servicenow San Diego Patch 3 Hotfix 1

ServiceNow has released upgrades and patches that address a Reflected Cross-Site scripting (XSS) vulnerability that was identified in the ServiceNow Polaris Layout. This vulnerability would enable an authenticated user to inject arbitrary scripts.

ServiceNow has released patches and an upgrade that address an Access Control List (ACL) bypass issue in ServiceNow Core functionality.

Additional Details

This issue is present in the following supported ServiceNow releases:

* Quebec prior to Patch 10 Hot Fix 8b
* Rome prior to Patch 10 Hot Fix 1
* San Diego prior to Patch 7
* Tokyo prior to Tokyo Patch 1; and
* Utah prior to Utah General Availability

If this ACL bypass issue were to be successfully exploited, it potentially could allow an authenticated user to obtain sensitive information from tables missing authorization controls.

Cross-Site Scripting (XSS) vulnerabilities exist in ServiceNow records allowing an authenticated attacker to inject arbitrary scripts.

There exists an open redirect within the response list update functionality of ServiceNow. This allows attackers to redirect users to arbitrary domains when clicking on a URL within a service-now domain.

A XSS vulnerability was identified in the ServiceNow UI page assessment_redirect. To exploit this vulnerability, an attacker would need to persuade an authenticated user to click a maliciously crafted URL. Successful exploitation potentially could be used to conduct various client-side attacks, including, but not limited to, phishing, redirection, theft of CSRF tokens, and use of an authenticated user's browser or session to attack other systems.
