Vendor description:  
-------------------  
"SAP is one of the world’s leading producers of software for the management of  
business processes."[1]

[1] https://www.sap.com/about/what-is-sap.html

Business recommendation:  
------------------------  
By exploiting the vulnerability documented in this advisory, attackers  
can redirect users to arbitrary sites. Targeted users of such an  
attack may be victims of successful phishing attempts jeopardizing the  
confidentiality of logon information or other data.

SEC Consult recommends to implement the security note 3258950, where the  
documented issue is fixed according to the vendor. We advise installing  
the correction as a matter of priority to keep business-critical data secure.

Vulnerability overview/description:  
-----------------------------------  
1) Open Redirect Vulnerability (Patch bypass of CVE-2020-6215)  
The sample Business Server Pages (BSP) application it00 suffers from an open  
redirect vulnerability that is referred to by CVE-2020-6215 [2]. A patch  
for this issue was made available via SAP Security Note 2872782 [3].  
During analysis, it was identified that the patch is insufficient and can  
be bypassed.

[2] https://nvd.nist.gov/vuln/detail/CVE-2020-6215  
[3] https://me.sap.com/notes/2872782

Proof of concept:  
-----------------  
1) Open Redirect Vulnerability (Patch bypass of CVE-2020-6215)  
The following source code excerpt of event handler OnInputProcessing() of  
BSP subpage transition_navigation.htm shows that by the implementation of  
SAP Security Note 2872782, an additional check was introduced that validates  
the HTTP request parameter ‘applicationUrl’ against pseudo-headers ~server_name,  
respectively ~server_name_expanded. Thus, to verify that the provided URL  
complies with these values to only allow redirects to the local server,  
the IF condition checks if the specified ‘applicationUrl’ parameter contains  
the host name of the local server. Only if this check is evaluated successfully,  
the browser of the calling user gets redirected to the intended page.

---------------------------------------------------------------------------  
[...]  
when 'call'.  
     data: url1      type string,  
           url2      type string,  
           host_name type string.  
     host_name = request->get_header_field( '~server_name' ).  
     if host_name is initial.  
       host_name = request->get_header_field( '~server_name_expanded' ).  
     endif.  
     url = request->get_form_field( 'applicationUrl' ).  
     if url cs host_name.  
       split url at '?' into url1 url2.  
       url2 = cl_abap_dyn_prg=>escape_xss_url( url2 ).  
       concatenate url1 '?' url2 into url.  
       navigation->call_application( url = url ).  
     endif.  
* negative test cases  
   when 'error_no_such_exit'.  
     navigation->next_page( 'NAVFAIL' ).

endcase.  
---------------------------------------------------------------------------

It was observed that this check can be bypassed, for example, by crafting  
special HTTP requests that contain the host name of the target application  
server (the PoC uses the <app server hostname> placeholder) within the query string  
part of the URL provided via parameter ‘applicationUrl’. To validate this issue,  
the following URL can be browsed to in order to trigger the vulnerability and  
circumvent the implemented patch.

---------------------------------------------------------------------------  
http[s]://<app server hostname>:<ICM port>/sap/bc/bsp/sap/it00/transition_  
navigation.htm?ApplicationURL=http://127.0.0.1:8080/?<app server hostname>  
&onInputProcessing%28call%29=Start+Application  
---------------------------------------------------------------------------

For demonstration purposes, after a successful login, the browser is redirected  
by the application server to localhost on port 8080 (any other host/port pair  
could by specified by the attacker).

The server replies with a "302 Found" message redirecting the browser to the  
localhost address defined in the response Location header field:

---------------------------------------------------------------------------  
HTTP/2 302 Found  
Content-Type: text/html  
Content-Length: 0  
Location: http://127.0.0.1:8080/?<app server hostname>&sap-params=[...]  
---------------------------------------------------------------------------

An attacker can create a URL which would redirect the victim to a malicious  
site, for example, a phishing site convincing the victim to login once again.

Vulnerable / tested versions:  
-----------------------------  
The following version has been tested and found to be vulnerable:

- SAP_BASIS release 755, SP level 01

According to the vendor the following releases and versions  
are affected by the discovered vulnerability:

- SAP_BASIS 700-702  
- SAP_BASIS 731  
- SAP_BASIS 740  
- SAP_BASIS 750-757

Vendor contact timeline:  
------------------------  
2022-10-03: Contacting vendor through vulnerability submission web form.  
2022-10-04: Vendor confirms receipt and assigns internal ID #2270141902.  
2022-10-19: Vendor confirms vulnerability and proposes new CVSS score of  
             5.4 (NLNR|U|LLN).  
2022-10-24: Asking vendor why new CVSS rating differs from initial  
             vulnerability rating. No response.  
2022-11-24: Asking vendor for update.  
2022-11-30: Vendor states that the patch is about to be released with the  
             upcoming Patch Tuesday December 2022.  
2022-12-13: Vendor releases patch with SAP Security Note 3258950.  
2023-10-05: Release of security advisory.

Solution:  
---------  
The vendor provides a patched version which should be installed immediately.  
Patches are available in form of SAP Security Notes which can be accessed  
via the SAP Customer Launchpad [4]. More information can also be found in  
the Official SAP Security Patchday Blog [5].

The following Security Note needs to be implemented: 3258950

[5] https://dam.sap.com/mac/app/e/pdf/preview/embed/ucQrx6G?ltr=a&rc=10

Workaround:  
-----------  
Disable BSP test application it00 in the ICF service tree in transaction  
SICF.
