SAP » Netweaver : Security Vulnerabilities, CVEs, CVSS score >= 6

The ABAP Application Server of SAP NetWeaver as well as ABAP Platform allows an attacker to prevent legitimate users from accessing a service, either by crashing or flooding the service. This leads to a considerable impact on availability.

Self-Registration and Modify your own profile in User Admin Application of NetWeaver AS Java does not enforce proper security requirements for the content of the newly defined security answer. This can be leveraged by an attacker to cause profound impact on confidentiality and low impact on both integrity and availability.

SAP NetWeaver AS Java (CAF - Guided Procedures) - version 7.50, allows an unauthenticated attacker to submit a malicious request with a crafted XML file over the network, which when parsed will enable him to access sensitive files and data but not modify them. There are expansion limits in place so that availability is not affected.

Under certain conditions, Internet Communication Manager (ICM) or SAP Web Dispatcher - versions KERNEL 7.22, KERNEL 7.53, KERNEL 7.54, KRNL64UC 7.22, KRNL64UC 7.22EXT, KRNL64UC 7.53, KRNL64NUC 7.22, KRNL64NUC 7.22_EXT, WEBDISP 7.22_EXT, WEBDISP 7.53, WEBDISP 7.54, could allow an attacker to access information which would otherwise be restricted causing high impact on confidentiality.

Due to programming error in function module and report, IS-OIL component in SAP ECC and SAP S/4HANA allows an authenticated attacker to inject an arbitrary operating system command into an unprotected parameter in a common (default) extension.  On successful exploitation, the attacker can read or modify the system data as well as shut down the system.

SAP NetWeaver Enterprise Portal - version 7.50, does not sufficiently encode user-controlled inputs over the network, resulting in reflected Cross-Site Scripting (XSS) vulnerability, therefore changing the scope of the attack. On successful exploitation, an attacker can view or modify information causing a limited impact on confidentiality and integrity of the application.

SAP NetWeaver (Design Time Repository) - version 7.50, returns an unfavorable content type for some versioned files, which could allow an authorized attacker to create a file with a malicious content and send a link to a victim in an email or instant message. Under certain circumstances, this could lead to Cross-Site Scripting vulnerability.

In SAP NetWeaver (BI CONT ADDON) - versions 707, 737, 747, 757, an attacker can exploit a directory traversal flaw in a report to upload and overwrite files on the SAP server. Data cannot be read but if a remote attacker has sufficient (administrative) privileges then potentially critical OS files can be overwritten making the system unavailable.

SAP GUI for HTML - versions KERNEL 7.22, 7.53, 7.54, 7.77, 7.81, 7.85, 7.89, 7.91, KRNL64UC, 7.22, 7.22EXT, KRNL64UC 7.22, 7.22EXT does not sufficiently encode user-controlled inputs, resulting in a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could craft a malicious URL and lure the victim to click, the script supplied by the attacker will execute in the victim user's browser. The information from the victim's web browser can either be modified or read and sent to the attacker.

Due to insufficient encoding of user input, SAP NetWeaver - versions 700, 701, 702, 731, 740, 750, allows an unauthenticated attacker to inject code that may expose sensitive data like user ID and password, which could lead to reflected Cross-Site scripting. These endpoints are normally exposed over the network and successful exploitation can partially impact confidentiality of the application.

Due to an uncontrolled recursion in SAP Web Dispatcher and SAP Internet Communication Manager, the application may crash, leading to denial of service, but can be restarted automatically.

By overlong input values an attacker may force overwrite of the internal program stack in SAP Web Dispatcher - versions 7.53, 7.77, 7.81, 7.85, 7.86, or Internet Communication Manager - versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, which makes these programs unavailable, leading to denial of service.

Some part of SAP NetWeaver (EP Web Page Composer) does not sufficiently validate an XML document accepted from an untrusted source, which allows an adversary to exploit unprotected XML parking at endpoints, and a possibility to conduct SSRF attacks that could compromise system?s Availability by causing system to crash.

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.

SAP NetWeaver - versions 700, 701, 702, 730, does not sufficiently encode user-controlled inputs, allowing an attacker to cause a potential victim to supply a malicious content to a vulnerable web application, which is then reflected to the victim and executed by the web browser, resulting in Cross-Site Scripting vulnerability.

SAP NetWeaver (Visual Composer 7.0 RT) versions - 7.30, 7.31, 7.40, 7.50, without restriction, an attacker authenticated as a non-administrative user can upload a malicious file over a network and trigger its processing, which is capable of running operating system commands with the privilege of the Java Server process. These commands can be used to read or modify any information on the server or shut the server down making it unavailable.

The MigrationService, which is part of SAP NetWeaver versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not perform an authorization check. This might allow an unauthorized attacker to access configuration objects, including such that grant administrative privileges. This could result in complete compromise of system confidentiality, integrity, and availability.

SAP NetWeaver - XML Toolkit for JAVA (ENGINEAPI) (versions- 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50), under certain conditions allows an attacker to access information which would otherwise be restricted, leading to Information Disclosure.

SAP NetWeaver UDDI Server (Services Registry), versions- 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50; 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, leading to Path Traversal.

Under certain conditions, ABAP Online Community in SAP NetWeaver (SAP_BASIS version 7.40) and SAP S/4HANA (SAP_BASIS versions 7.50, 7.51, 7.52, 7.53, 7.54), does not sufficiently encode user-controlled inputs, resulting in Reflected Cross-Site Scripting (XSS) vulnerability.

A remote code execution vulnerability exists in the SAP NetWeaver UDDI Server (Services Registry), versions 7.10, 7.20, 7.30, 7.31, 7.40, 7.50. Because of this, an attacker can exploit Services Registry potentially enabling them to take complete control of the product, including viewing, changing, or deleting data by injecting code into the working memory which is subsequently executed by the application. It can also be used to cause a general fault in the product, causing the product to terminate.

Knowledge Management (XMLForms) in SAP NetWeaver, versions 7.30, 7.31, 7.40 and 7.50 does not sufficiently validate an XML document accepted from an untrusted source.

Due to insufficient URL Validation in forums in SAP NetWeaver versions 7.30, 7.31, 7.40, an attacker can redirect users to a malicious site.

In SAP NetWeaver Application Server for ABAP, from 7.0 to 7.02, 7.30, 7.31, 7.40 and from 7.50 to 7.53, applications do not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.

SAP WebDynpro Java, versions 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs, resulting in a stored Cross-Site Scripting (XSS) vulnerability.
