Detailsinfo

A vulnerability was found in Cisco Switch (affected version not known). It has been classified as critical. This affects some unknown functionality of the component Web Framework. The manipulation with an unknown input leads to a response splitting vulnerability (HTTP Response Splitting). CWE is classifying the issue as CWE-113. The product receives data from an HTTP agent/component (e.g., web server, proxy, browser, etc.), but it does not neutralize or incorrectly neutralizes CR and LF characters before the data is included in outgoing HTTP headers.
