Information Disclosure in LVM 2.1 and LaMa 3.0, SAP security note 2531241

Description

UPDATE 14th November 2017: This note has been re-released with updated CVSS Information and Priority.

Under certain conditions LVM 2.1 and LaMa 3.0 allows an attacker with LaMa J2EE Database administrator rights to read passwords or confidential management information of managed systems. The information disclosed are:

  1. Secure parameters transferred to Custom Hooks for HANA Live Cylce Management Operations starting with the prefix hdblcm*,
  2. Secure parameters transferred to Custom Hooks for Software Provisioning Manager Operations starting with the prefix SAPINST_*.

This may give an attacker the chance to connect to instances installed/modified by HANA Live Cylce Manager and/or Software Provisioning Manager since administrative passwords are part of the secure parameters.

The information is stored without encryption in the LVM/LaMa database.

Note: Check Reasons and Prerequisites to see if the impact is relevant to your Lama Usage Scenario.
