SAP Web Application Server Multiple Cross Site Scripting Vulnerabilities

Description

Multiple vulnerabilities were identified in SAP Web Application Server, which may be exploited by attackers to conduct cross site scripting, HTTP response splitting and phishing attacks.
The first issue is due to an input validation error in the BSP runtime when processing a specially crafted "sap-exiturl" parameter, which may be exploited by attackers to perform HTTP response splitting and cause arbitrary scripting code to be executed by the user's browser.
The second vulnerability is due to an input validation error in the BSP runtime when processing a specially crafted "sapexiturl" parameter passed to the "menu/fameset.htm" script, which could be exploited by attackers to redirect a user from the application to a malicious Web page.
The third flaw is due to input validation errors in the BSP runtime when displaying certain error pages and when processing a specially crafted "syscmd" or "BspApplication" parameter, which may be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser.
