SAP Note Assistant tool (SAP BASIS from 7.00 to 7.02, from 7.10 to 7.11, 7.30, 7.31,7.40, from 7.50 to 7.52) supports upload of digitally signed note file of type 'SAR'. The digital signature verification is done together with the extraction of note file contained in the SAR archive. It is possible to append a tampered file to the SAR archive using SAPCAR tool and during the extraction, digital signature verification fails but the tampered file is extracted.

Necessary authorization checks for an authenticated user, resulting in escalation of privileges, have been fixed in SAP Basis AS ABAP of SAP NetWeaver 700 to 750, from 750 onwards delivered as ABAP Platform.

ABAP File Interface in, SAP BASIS, from 7.00 to 7.02, from 7.10 to 7.11, 7.30, 7.31, 7.40, from 7.50 to 7.52, allows an attacker to exploit insufficient validation of path information provided by users, thus characters representing "traverse to parent directory" are passed through to the file APIs.

SAP NetWeaver, SAP BASIS from 7.00 to 7.02, from 7.10 to 7.11, 7.30, 7.31, 7.40, from 7.50 to 7.52, contains code that allows you to execute arbitrary program code of the user's choice. A malicious user can therefore control the behaviour of the system or can potentially escalate privileges by executing malicious code without legitimate credentials.

SAP Kernel (ABAP Debugger), versions KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, KRNL64UC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.73, KERNEL 7.21, 7.49, 7.53, 7.73, 7.75, 7.76, 7.77, allows a user to execute “Go to statement” without possessing the authorization SDEVELOP DEBUG 02, resulting in Missing Authorization Check

FTP Function of SAP NetWeaver AS ABAP Platform, versions- KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, KRNL64UC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.73, KERNEL 7.21, 7.45, 7.49, 7.53, 7.73, allows an attacker to inject code or specifically manipulated command that can be executed by the application. An attacker could thereby control the behaviour of the application.

ABAP BASIS function modules INSTCREATER3RFCDEST, INSTCREATETCPIPRFCDEST, and INSTCREATETCPIPRFCDEST in SAP BASIS (fixed in versions 7.0 to 7.02, 7.10 to 7.30, 7.31, 7.40, 7.50 to 7.53) do not perform necessary authorization checks in all circumstances for an authenticated user, resulting in escalation of privileges.

ABAP Server (used in NetWeaver and Suite/ERP) and ABAP Platform does not sufficiently validate an XML document accepted from an untrusted source, leading to an XML External Entity (XEE) vulnerability. Fixed in Kernel 7.21 or 7.22, that is ABAP Server 7.00 to 7.31 and Kernel 7.45, 7.49 or 7.53, that is ABAP Server 7.40 to 7.52 or ABAP Platform. For more recent updates please refer to Security Note 2870067 (which supersedes the solution of Security Note 2736825) in the reference section below.

ABAP Server of SAP NetWeaver and ABAP Platform fail to perform necessary authorization checks for an authenticated user, resulting in escalation of privileges. This has been corrected in the following versions: KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.74, KRNL64UC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.73, 7.74, 8.04, KERNEL 7.21, 7.45, 7.49, 7.53, 7.73, 7.74, 7.75, 8.04.

SLD Registration of ABAP Platform allows an attacker to prevent legitimate users from accessing a service, either by crashing or flooding the service. Fixed in versions KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT,KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49,KRNL64UC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49. 7.73 KERNEL from 7.21 to 7.22, 7.45, 7.49, 7.53, 7.73, 7.75.

SAP NetWeaver AS ABAP Platform, Krnl64nuc 7.74, krnl64UC 7.73, 7.74, Kernel 7.73, 7.74, 7.75, fails to validate type of installation for an ABAP Server system correctly. That behavior may lead to situation, where business user achieves access to the full SAP Menu, that is 'Easy Access Menu'. The situation can be misused by any user to leverage privileges to business functionality.
