Description

This security bulletin contains information about 5 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2020-6287)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber


The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to multiple unspecified issues within the SAP NetWeaver AS JAVA (LM Configuration Wizard). A remote non-authenticated attacker can send specially crafted request to the application and execute arbitrary code on the system.


2) Information disclosure (CVE-ID: CVE-2020-6285)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear


The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to unspecified error within the SAP NetWeaver (XML Toolkit for JAVA). A remote authenticated user can gain unauthorized access to sensitive information on the system.


3) Cross-site request forgery (CVE-ID: CVE-2020-6282)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin within SAP NetWeaver AS JAVA (IIOP service) for both service core and core-tools deployments. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
