SAP HANA database is vulnerable to privilege escalation allowing an attacker with valid credentials of any user to switch to another user potentially gaining administrative access. This exploit could result in a total compromise of the system�s confidentiality, integrity, and availability.
SAP CommonCryptoLib does not perform necessary authentication checks, which may result in missing or wrong authorization checks for an authenticated user, resulting in escalation of privileges. Depending on the application and the level of privileges acquired, an attacker could abuse functionality restricted to a particular user group as well as read, modify or delete restricted data.
SAP CommonCryptoLib allows an unauthenticated attacker to craft a request, which when submitted to an open port causes a memory corruption error in a library which in turn causes the target component to crash making it unavailable. There is no ability to view or modify any information.
SAP HANA Database, versions - 1.0, 2.0, accepts SAML tokens with MD5 digest, an attacker who manages to obtain an MD5-digest signed SAML Assertion issued for an SAP HANA instance might be able to tamper with it and alter it in a way that the digest continues to be the same and without invalidating the digital signature, this allows them to impersonate as user in HANA database and be able to read the contents in the database.
SAP HANA Database, version - 2.0, does not correctly validate the username when performing SAML bearer token-based user authentication. It is possible to manipulate a valid existing SAML bearer token to authenticate as a user whose name is identical to the truncated username for whom the SAML bearer token was issued.
SAP HANA Database, versions 1.0, 2.0, allows an unauthorized attacker to send a malformed connection request, which crashes the indexserver of an SAP HANA instance, leading to Denial of Service
SAP UI5 did not validate user input before adding it to the DOM structure. This may lead to malicious user-provided JavaScript code being added to the DOM that could steal user information. Software components affected are: SAP Hana Database 1.00, 2.00; SAP UI5 1.00; SAP UI5 (Java) 7.30, 7.31, 7.40, 7,50; SAP UI 7.40, 7.50, 7.51, 7.52, and version 2.0 of SAP UI for SAP NetWeaver 7.00
The user self-service tools of SAP HANA extended application services, classic user self-service, a part of SAP HANA Database versions 1.00 and 2.00, can be misused to enumerate valid and invalid user accounts. An unauthenticated user could use the error messages to determine if a given username is valid.
