SAP NetWeaver AS JAVA (P2P Cluster Communication), versions - 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, allows arbitrary connections from processes because of missing authentication check, that are outside the cluster and even outside the network segment dedicated for the internal cluster communication. As result, an unauthenticated attacker can invoke certain functions that would otherwise be restricted to system administrators only, including access to system administration functions or shutting down the system completely.

Standalone clients connecting to SAP NetWeaver AS Java via P4 Protocol, versions (SAP-JEECOR 7.00, 7.01; SERVERCOR 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50; CORE-TOOLS 7.00, 7.01, 7.02, 7.05, 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50) do not perform any authentication checks for operations that require user identity leading to Authentication Bypass.

SAP NetWeaver AS JAVA, versions - (ENGINEAPI 7.10; WSRM 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50; J2EE-FRMW 7.10, 7.11), does not perform any authentication checks for a web service allowing the attacker to send several payloads and leading to complete denial of service.

SAP NetWeaver AS for Java (Http Service Monitoring Filter), versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, allows an attacker to send multiple HTTP requests with different method types thereby crashing the filter and making the HTTP server unavailable to other legitimate users leading to denial of service vulnerability.

By default, the SAP NetWeaver AS Java keystore service does not sufficiently restrict the access to resources that should be protected. This has been fixed in SAP NetWeaver AS Java (ServerCore versions 7.11, 7.20, 7.30, 7.31, 7.40, 7.50).

SAP NetWeaver Application Server Java, versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, and 7.50 allows an unauthenticated attacker to include JavaScript blocks in any web page or URL with different symbols which are otherwise not allowed. On successful exploitation an attacker can steal authentication information of the user, such as data relating to his or her current session and limitedly impact confidentiality and integrity of the application, leading to Reflected Cross Site Scripting.

SAP Netweaver Application Server Java (Applications based on WebDynpro Java) versions 7.00, 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, allow an attacker to redirect users to a malicious site due to Reverse Tabnabbing vulnerabilities.

The logon application of SAP NetWeaver AS Java 7.10 to 7.11, 7.20, 7.30, 7.31, 7.40, 7.50 does not sufficiently encode user-controlled inputs, resulting in a cross-site scripting (XSS) vulnerability.

SAP NetWeaver AS Java, versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, Start Page allows an unauthenticated remote attacker to redirect users to a malicious site due to insufficient reverse tabnabbing URL validation. The attacker could execute phishing attacks to steal credentials of the victim or to redirect users to untrusted web pages containing malware or similar malicious exploits.

SAP NetWeaver AS Java Web Container service does not validate against whitelist the HTTP host header which can result in HTTP Host Header Manipulation or Cross-Site Scripting (XSS) vulnerability. This is fixed in versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50.

SAP NetWeaver AS JAVA (IIOP service) (SERVERCORE), versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, and SAP NetWeaver AS JAVA (IIOP service) (CORE-TOOLS), versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, allows an attacker to send a crafted request from a vulnerable web application. It is usually used to target internal systems behind firewalls that are normally inaccessible to an attacker from the external network, resulting in a Server-Side Request Forgery vulnerability.

SAP AS JAVA (Key Storage Service), versions - 7.10, 7.11, 7.20 ,7.30, 7.31, 7.40, 7.50, has the key material which is stored in the SAP NetWeaver AS Java Key Storage service stored in the database in the DER encoded format and is not encrypted. This enables an attacker who has administrator access to the SAP NetWeaver AS Java to decode the keys because of missing encryption and get some application data and client credentials of adjacent systems. This highly impacts Confidentiality as information disclosed could contain client credentials of adjacent systems.

SAP NetWeaver AS Java (Applications based on HTMLB for Java) allows a basic-level authorized attacker to store a malicious file on the server. When a victim tries to open this file, it results in a Cross-Site Scripting (XSS) vulnerability and the attacker can read and modify data. However, the attacker does not have control over kind or degree.

SAML 1.1 SSO Demo Application in SAP NetWeaver Java Application Server (J2EE-APPS), versions 7.10 to 7.11, 7.20, 7.30, 7.31, 7.40 and 7.50, does not sufficiently encode user-controlled inputs, which results in cross-site scripting (XSS) vulnerability.

SAP NetWeaver Application Server Java(HTTP Service), versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently validate logon group in URLs, resulting in a content spoofing vulnerability when directory listing is enabled.
