Description:
Cybsec S.A. has reported some vulnerabilities in SAP Web Application Server, which can be exploited by malicious people to conduct cross-site scripting, phishing, and HTTP response splitting attacks.
1) Input passed to the "sap-syscmd" parameter in "fameset.htm" and the "BspApplication" field in the "SYSTEM PUBLIC" test application isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerabilities have been reported in versions 6.10, 6.20, 6.40, and 7.00, and affect the BSP runtime of SAP Web Application Server. Other versions may also be affected.
2) Input passed to the query string in pages generating error messages isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability has been reported in version 6.10 and affects the BSP runtime of SAP Web Application Server. Prior versions may also be affected.
3) The problem is that an absolute URL for an external site can be specified in the "sapexiturl" parameter passed to "fameset.htm". This can be exploited to trick users into visiting a malicious web site by following a specially crafted link with a trusted hostname redirecting to the malicious web site.
The vulnerabilities have been reported in versions 6.10, 6.20, 6.40, and 7.00, and affect the BSP runtime of SAP Web Application Server. Other versions may also be affected.
4) Input passed to the "sap-exiturl" parameter isn't properly sanitised before being returned to the user. This can be exploited to inject arbitrary HTTP headers, which will be included in the response sent to the user.
The vulnerabilities have been reported in versions 6.10, 6.20, 6.40, and 7.00, and affect the BSP runtime of SAP Web Application Server. Other versions may also be affected.

The vendor has reportedly provided a solution for the vulnerabilities. Customers should contact the SAP's support for further information.
