Vulnerability
===============
During our research we discovered a stack-based buffer overflow in
the Extended Passport (EPP) processing, kernel code shared by
several SAP components: the SAP Internet Communication Manager
(ICM), the SAP Web Dispatcher, and the disp+work work processes of
the ABAP application server. Missing bounds validation on
externally supplied metadata corrupts stack memory and allows an
unauthenticated remote attacker to redirect the execution flow,
gaining full control of the SAP server.
The vulnerable code is reachable through several protocols, all of
them before authentication: HTTP and HTTPS, the WebSocket RFC
(NGRFC) protocol, classic RFC, and the SAP GUI (DIAG) protocol.
This advisory demonstrates three of these paths in the laboratory:
1. HTTP(S) into the ICM: the overflow executes inside the Internet
Communication Manager itself.
2. WebSocket RFC (NGRFC) into a disp+work dialog work process: the
Internet-facing ICM terminates the WebSocket connection and
hands the crafted NGRFC login envelope to a dialog work process,
which parses it before any logon check. With an SAP Web
Dispatcher in front, it tunnels the upgraded connection to the
ICM first.
3. Classic RFC into a disp+work dialog work process: the gateway
accepts the same TLV login structure, including the crafted
passport, before sign-on.
NGRFC, SAP's WebSocket-based Next Generation RFC, tunnels classic
RFC (a protocol family from the R/2 and R/3 era) over WebSocket and
HTTPS. Until NGRFC, work processes were reachable only through the
internal DIAG and classic RFC ports. NGRFC exposes the work
process, the component that executes the ABAP business logic and
holds database connections, credentials and active user sessions,
through the Internet-facing HTTPS port for the first time. Systems
whose administrators disabled WebSocket support, believing this
path to be closed, remain fully exposed: laboratory tests showed
the vulnerable code is still reachable without authentication over
the Internet-facing port. The classic RFC protocol carries the same
Extended Passport processing, so transport-level switches cannot
substitute for the kernel patch.
In the laboratory, nullFaktor escalated the overflow over the
network to full remote code execution, in the context of the ICM
process or, via the WebSocket RFC path, of a disp+work dialog work
process. The code execution chain combines control of the saved
instruction pointer with a memory leak that resolves process
addresses and defeats ASLR. The memory-leak primitive, the resolved
address data, the payload and the detailed trigger conditions are
withheld from this advisory for now and will be published at a
later time. The leak will be covered in a separate advisory.
Because the EPP processing code is part of the kernel library linked
into the work processes themselves, the same input also reaches a
disp+work process over classic RFC (gateway port 33<NN>) and over
the DIAG protocol (SAP GUI logons, dispatcher port 32<NN>). The
classic RFC path is confirmed in the laboratory (see the Proof of
Concept section); the DIAG path follows from the same shared code.
The affected stack frame is not protected by a stack canary,
although the binary is compiled with canary support, so the
overwrite continues uninterrupted until the function returns into
the chosen address. The Proof of Concept section verifies this
against the binary and at runtime.
The EPP component and the missing boundary validation are identified
in SAP Security Note 3747649.

Tested Environment:
====================
Product: SAP NetWeaver AS ABAP (S/4HANA)
Kernel: 793, patch 101 (Aug 2 2024)
SAP_BASIS: 757 SP 3
Platform: Linux x86_64
Affected Products and Correction Levels:
========================================
The following vendor scope and correction levels are taken from SAP
Security Note 3747649, version 7, released September 8, 2026.
Affected products according to SAP:
- SAP NetWeaver AS ABAP and Java with kernel patch levels below the
applicable correction level listed in the note.
- SAP Web Dispatcher 9.16 with patch levels below 100.
SAP explicitly excludes other SAP Web Dispatcher versions and the Web
Dispatcher included in SAP HANA Extended Application Services.
All kernel releases named in the note are listed with their correction
levels in the table below.
Correction entries from the note's Support Package Patches section:
Software component / variant Support Package Patch Level
------------------------------------------- --------------- -----------
SAP KERNEL 7.22 EXT, 64-BIT / 64-BIT UC SP1518 001518

SAP KERNEL 9.20, 64-BIT UNICODE SP004 000004
SAP WEB DISPATCHER 9.16 SP100 000100
SAP states that higher patch levels also contain the correction for
the applicable release. For kernel 7.93, the note lists both patch 401
and patch 412 without explaining the distinction. Both entries are
preserved here. Consult SAP's package applicability when selecting the
update for a particular installation.
As of note version 7 (September 8, 2026), no separate correction entry
exists for plain kernel 7.22 or kernel 7.89, so no fixed patch level
can be stated for these releases. SAP advises that kernels that are
out of maintenance and for which no correction is available be
upgraded to the corresponding downward-compatible kernel (DCK). See
SAP Note 2083594.
The note's Software Components section also lists WEBDISP 9.18,
9.19 and 9.20. The note does not explain these entries. Because
SAP's explicit affected-release statement limits the affected Web
Dispatcher product to version 9.16 and states that other Web
Dispatcher versions are not affected, these component entries are
not treated as affected Web Dispatcher versions in this advisory.

Title
[SYSS-2026-004] SAP NetWeaver SAML XML Signature Wrapping
Summary
Advisory ID: SYSS-2026-004
Product: SAP NetWeaver ABAP / SAP_BASIS
Manufacturer: SAP SE
Affected Version(s): SAP_BASIS 700 - 918
Tested Version(s): 7.93 Patch 300
Vulnerability Type: CWE-347: Improper Verification of Cryptographic Signature
Risk Level: High
Solution Status: Fixed
Manufacturer Notification: 2025-11-06
Solution Date: 2026-02-10
Public Disclosure: 2026-06-08
CVE Reference: CVE-2026-23687
Author of Advisory: Moritz Bechler, SySS GmbH
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overview:
SAP NetWeaver is the software stack powering SAP's business applications,
including S4/HANA.
The manufacturer describes the product as follows (see [1]):
"SAP NetWeaver provides an open integration and application platform and
facilitates the implementation of the Enterprise Services Architecture.
You can standardize business processes across technological boundaries,
integrate applications for your employees as required, and access and edit
simple information easily and in a structured manner.
[...]
SAP NetWeaver is the basis for SAP solutions."
SAML response validation in NetWeaver's SAML Service Provider is susceptible
to XML Signature wrapping attacks, specifically through Signature/Object tags.
This allows an attacker to manipulate SAML assertion data returned by the
identity provider, therefore enabling logging in as an arbitrary user.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Vulnerability Details:
In SAML authentication responses, the SAML assertion/user identity attributes
are cryptographically signed by the identity provider using the XML Signature
(XMLDSig) standard. In web single sign-on contexts, the SAML response is
passed through the authenticating user's browser and therefore very susceptible
to modification.
When verifying a specially crafted SAML response, the SAMP service provider
implementation verifies the signature over one part of the XML document while
using information from another element to identify the authenticated user.
Providing original, legitimate information from any valid SAML response in
the first part and the corresponding signature, along with a manipulated
alternative part, authentication to the SAP system as an arbitrary
SAML-enabled / mapped user is possible.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
A typical (non-encrypted, assertion signing) SAML response will have a structure
like the following (various irrelevant elements are removed for brevity):
<samlp:Response>
<Assertion ID="MyID">
<Signature>
<SignedInfo>
<Reference URI="#MyID">
<DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"; />
<DigestValue>[...]</DigestValue>
</Reference>
</SignedInfo>
<SignatureValue>[...]</SignatureValue>
<KeyInfo>
<X509Data><X509Certificate>[...]</X509Certificate></X509Data>
</KeyInfo>
</Signature>
<Subject><...></Subject>
<AttributeStatement>
<Attribute Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name";>
<AttributeValue>originaluser@mydomain.example</AttributeValue>
</Attribute>
<...>
</AttributeStatement>
</Assertion>
</samlp:Response>
The XML Signature specification is very flexible (read: complex), leaving
significant room for ambiguities and implementation errors. Apart from
referencing the data to be signed/verified through the <Reference> element,
the signed data can also be directly included in the <Signature> element
through an <Object> tag (see [4]).
Doing so is fully specified and conformant with the XML schema.
Transforming the SAML response to use the <Object> syntax yields the following:
<samlp:Response>
<Assertion ID="MyID">
<Signature>
<SignedInfo>
<Reference URI="#MyID">
<DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"; />
<DigestValue>[...]</DigestValue>
</Reference>
</SignedInfo>
<SignatureValue>[...]</SignatureValue>
<KeyInfo>
<X509Data><X509Certificate>[...]</X509Certificate></X509Data>
</KeyInfo>
<Object>
<Assertion ID="MyID">
<Subject><...></Subject>
<AttributeStatement>
<Attribute Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name";>
<AttributeValue>originaluser@mydomain.example</AttributeValue>
</Attribute>
<...>
</AttributeStatement>
</Assertion>
</Object>
</Signature>
<Subject><...></Subject>
<AttributeStatement>
<Attribute Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name";>
<AttributeValue>myadmin@mydomain.example</AttributeValue>
</Attribute>
<...>
</AttributeStatement>
</Assertion>
</samlp:Response>
This is a well-known and published attack vector against XML signatures.
A graphical representation of this transformation is given in [5], also
the Burp SAML Raider extension provides a convenient way to execute the
attack (XSW8).
As the signed elements have not changed, the XML Signature element is still
valid and can be verified. The XML Signature implementation used in NetWeaver
now calculates the hash value for verification of the signature over the
<Object> element's contents.
Now, the original copy of the data within the outer <Assertion> element
can be modified without invalidating the signature, and this is the
information extracted and used by NetWeaver to determine the identity of
the authenticated SAP user.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not sufficiently validate certain incoming requests before forwarding them to backend destinations. Due to the complexity of the required conditions, an attacker with low privileges could send specially crafted requests to bypass authorization checks and reach protected resources beyond their assigned scope. Successful exploitation could allow the attacker to read sensitive data and perform limited modifications on protected resources, resulting in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not consistently enforce integrity verification on certain session-related request headers under specific conditions. An attacker with low privileges could send a specially crafted request that bypasses the integrity check and loads another user's session context. Successful exploitation requires the attacker to have previously observed matching session values out-of-band, which makes the attack complex to execute. This could result in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not enforce cross-site request forgery protection on the authentication flow by default. An unauthenticated attacker could craft a malicious link and trick a victim into following it. Successful exploitation could allow the attacker to bind the victim's session to an attacker-controlled identity, resulting in a low impact on integrity. There is no impact on confidentiality and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not consistently handle certain error conditions. An attacker with low privileges could exploit this under a non-default configuration. Successful exploitation is highly complex, as it depends on conditions outside the attacker's control. This could result in a low impact on availability. There is no impact on confidentiality and integrity.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not correctly validate client certificates in certain callback flows. An attacker with low privileges, holding a certificate from the same trusted authority with matching subject values, could bypass the identity check. This complexity makes the attack difficult to execute. Successful exploitation could allow impersonation of a trusted internal component, resulting in a high impact on integrity and a low impact on confidentiality and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not sufficiently validate tenant context in inbound requests. An unauthenticated attacker could send specially crafted requests to spoof the tenant context under conditions not fully within their control. Successful exploitation could allow limited access to another tenant's information, resulting in a low impact on confidentiality. There is no impact on integrity and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not sufficiently validate certain token content under specific configurations. An unauthenticated attacker could send a specially crafted token to cause sensitive credential material to be sent to an attacker-controlled destination. The attack complexity is high due to non-default preconditions required in the target environment. This results in a high impact on confidentiality and a low impact on integrity and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not sufficiently validate certain incoming requests before forwarding them to backend destinations. Due to the complexity of the required conditions, an attacker with low privileges could send specially crafted requests to bypass authorization checks and reach protected resources beyond their assigned scope. Successful exploitation could allow the attacker to read sensitive data and perform limited modifications on protected resources, resulting in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not consistently enforce integrity verification on certain session-related request headers under specific conditions. An attacker with low privileges could send a specially crafted request that bypasses the integrity check and loads another user's session context. Successful exploitation requires the attacker to have previously observed matching session values out-of-band, which makes the attack complex to execute. This could result in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.

Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not enforce cross-site request forgery protection on the authentication flow by default. An unauthenticated attacker could craft a malicious link and trick a victim into following it. Successful exploitation could allow the attacker to bind the victim's session to an attacker-controlled identity, resulting in a low impact on integrity. There is no impact on confidentiality and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not correctly validate client certificates in certain callback flows. An attacker with low privileges, holding a certificate from the same trusted authority with matching subject values, could bypass the identity check. This complexity makes the attack difficult to execute. Successful exploitation could allow impersonation of a trusted internal component, resulting in a high impact on integrity and a low impact on confidentiality and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not sufficiently validate tenant context in inbound requests. An unauthenticated attacker could send specially crafted requests to spoof the tenant context under conditions not fully within their control. Successful exploitation could allow limited access to another tenant's information, resulting in a low impact on confidentiality. There is no impact on integrity and availability.

Title
Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Summary
SAP Approuter does not sufficiently validate certain token content under specific configurations. An unauthenticated attacker could send a specially crafted token to cause sensitive credential material to be sent to an attacker-controlled destination. The attack complexity is high due to non-default preconditions required in the target environment. This results in a high impact on confidentiality and a low impact on integrity and availability.
