SAP Releases February 2022 Security Updates

CVE-2021-44228

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

CVE-2021-44832

Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2.

CVE-2021-45046

It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

CVE-2021-45105

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

CVE-2022-22528

SAP Adaptive Server Enterprise (ASE) - version 16.0, installation makes an entry in the system PATH environment variable in Windows platform which, under certain conditions, allows a Standard User to execute malicious Windows binaries which may lead to privilege escalation on the local system. The issue is with the ASE installer and does not impact other ASE binaries.

CVE-2022-22530

The F0743 Create Single Payment application of SAP S/4HANA - versions 100, 101, 102, 103, 104, 105, 106, does not check uploaded or downloaded files. This allows an attacker with basic user rights to inject dangerous content or malicious code which could result in critical information being modified or completely compromise the availability of the application.

CVE-2022-22531

The F0743 Create Single Payment application of SAP S/4HANA - versions 100, 101, 102, 103, 104, 105, 106, does not check uploaded or downloaded files. This allows an attacker with basic user rights to run arbitrary script code, resulting in sensitive information being disclosed or modified.

CVE-2022-22532

In SAP NetWeaver Application Server Java - versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC, 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, an unauthenticated attacker could submit a crafted HTTP server request which triggers improper shared memory buffer handling. This could allow the malicious payload to be executed and hence execute functions that could be impersonating the victim or even steal the victim's logon session.

CVE-2022-22533

Due to improper error handling in SAP NetWeaver Application Server Java - versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC, 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, an attacker could submit multiple HTTP server requests resulting in errors, such that it consumes the memory buffer. This could result in system shutdown rendering the system unavailable.

CVE-2022-22534

Due to insufficient encoding of user input, SAP NetWeaver allows an unauthenticated attacker to inject code that may expose sensitive data like user ID and password. These endpoints are normally exposed over the network and successful exploitation can partially impact confidentiality of the application.

CVE-2022-22535

SAP ERP HCM Portugal - versions 600, 604, 608, does not perform necessary authorization checks for a report that reads the payroll data of employees in a certain area. Since the affected report only reads the payroll information, the attacker can neither modify any information nor cause availability impacts.

CVE-2022-22536

SAP NetWeaver Application Server ABAP, SAP NetWeaver Application Server Java, ABAP Platform, SAP Content Server 7.53 and SAP Web Dispatcher are vulnerable for request smuggling and request concatenation. An unauthenticated attacker can prepend a victim's request with arbitrary data. This way, the attacker can execute functions impersonating the victim or poison intermediary Web caches. A successful attack could result in complete compromise of Confidentiality, Integrity and Availability of the system.

CVE-2022-22537

When a user opens a manipulated Tagged Image File Format (.tiff, 2d.x3d)) received from untrusted sources in SAP 3D Visual Enterprise Viewer - version 9.0, the application crashes and becomes temporarily unavailable to the user until restart of the application. The file format details along with their CVE relevant information can be found below.

CVE-2022-22538

When a user opens a manipulated Adobe Illustrator file format (.ai, ai.x3d) received from untrusted sources in SAP 3D Visual Enterprise Viewer - version 9.0, the application crashes and becomes temporarily unavailable to the user until restart of the application. The file format details along with their CVE relevant information can be found below.

CVE-2022-22539

When a user opens a manipulated JPEG file format (.jpg, 2d.x3d) received from untrusted sources in SAP 3D Visual Enterprise Viewer - version 9.0, the application crashes and becomes temporarily unavailable to the user until restart of the application. The file format details along with their CVE relevant information can be found below.

CVE-2022-22540

SAP NetWeaver AS ABAP (Workplace Server) - versions 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 756, 787, allows an attacker to execute crafted database queries, that could expose the backend database. Successful attacks could result in disclosure of a table of contents from the system, but no risk of modification possible.

CVE-2022-22542

S/4HANA Supplier Factsheet exposes the private address and bank details of an Employee Business Partner with Supplier Role, AND Enterprise Search for Customer, Supplier and Business Partner objects exposes the private address fields of Employee Business Partners, to an actor that is not explicitly authorized to have access to that information, which could compromise Confidentiality.

CVE-2022-22543

SAP NetWeaver Application Server for ABAP (Kernel) and ABAP Platform (Kernel) - versions KERNEL 7.22, 8.04, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, KRNL64UC 8.04, 7.22, 7.22EXT, 7.49, 7.53, KRNL64NUC 7.22, 7.22EXT, 7.49, does not sufficiently validate sap-passport information, which could lead to a Denial-of-Service attack. This allows an unauthorized remote user to provoke a breakdown of the SAP Web Dispatcher or Kernel work process. The crashed process can be restarted immediately, other processes are not affected.

CVE-2022-22544

Solution Manager (Diagnostics Root Cause Analysis Tools) - version 720, allows an administrator to execute code on all connected Diagnostics Agents and browse files on their systems. An attacker could thereby control the managed systems. It is considered that this is a missing segregation of duty for the SAP Solution Manager administrator. Impacts of unauthorized execution of commands can lead to sensitive information disclosure, loss of system integrity and denial of service.

CVE-2022-22546

Due to improper HTML encoding in input control summary, an authorized attacker can execute XSS vulnerability in SAP Business Objects Web Intelligence (BI Launchpad) - version 420.
