Detailsinfo

A vulnerability has been found in Google AngularJS 1.2.0-rc.3 and classified as critical. Affected by this vulnerability is an unknown functionality of the file angularjs.org of the component Regular Expression Handler. The manipulation with an unknown input leads to a incomplete filtering of special elements vulnerability. The CWE definition for the vulnerability is CWE-791. The product receives data from an upstream component, but does not completely filter special elements before sending it to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A flaw in AngularJS' Strict Contextual Escaping (SCE) logic allows bypassing certain SCE policies for resource URLs and can lead to arbitrary JavaScript execution within the context of the victim's browser session. SCE's purpose is to ensure that only trusted or safe values are used in certain security-sensitive contexts, such as resource URLs, including URLs that define executable JavaScript scripts, '' documents, route templates, etc. A flaw in the logic that tries to match entire URLs against regular expression matchers can result in partial matches for certain types of regular expressions, effectively bypassing the policies and allowing the use of unsafe values as resource URLs. This issue affects AngularJS versions greater than or equal to 1.2.0-rc.3. Note: The AngularJS project was already End-of-Life when this CVE was published and will not receive any updates to address this issue. For more information see the  End-of-Life announcement https://docs.angularjs.org/misc/version-support-status .
