SAP NetWeaver multiple vulnerabilities
Posted on 15 November 2011.
Digital Security Research Group has reported multiple vulnerabilities in SAP NetWeaver, which can be exploited by malicious users to conduct script insertion attacks, manipulate certain data, bypass certain security restrictions, and compromise a vulnerable system and by malicious people to conduct cross-site scripting and cross-site request forgery attacks, according to Secunia.


1. Input passed via certain transactions to the BAPI Explorer is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.

2. Input passed to the "instname" parameter in the VsiTestScan servlet and "name" parameter in the VsiTestServelet servlet within the Virus Scan Interface is not 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.

3. Input passed to the "page" parameter in /SAP/BW/DOC/METADATA/ is not 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.

4. An error in the RSTXSCRP report when using transaction "sa38" can be exploited to insert an arbitrary UNC path via the "File Name" field.

5. An error in the TH_GREP report when handling certain SOAP requests can be exploited to inject arbitrary shell commands via a "" parameter.

Successful exploitation of this vulnerability may allow execution of arbitrary code.

6. The SPML service allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. create an arbitrary user if a logged-in administrative user visits a malicious web site.

7. An error in the CTC service when performing certain authentication checks can be exploited to gain access to user management and OS command execution functionality.

Successful exploitation of this vulnerability may allow execution of arbitrary code.

Solution: Fixes are available.
