Vulnerabilities exist in EMC NMM that could potentially be exploited by a malicious user to execute arbitrary code. Also, there is a risk that sensitive information could be disclosed under specific circumstances described in the details below.
EMC NetWorker Module for Microsoft Applications Remote Code Execution Vulnerability (CVE-2012-2290)
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
A vulnerability exists in EMC NMM where the communication channel between the NMM components can remain unprotected in certain circumstances. This may allow a remote unauthenticated user to connect over TCP to a NMM Client and send a specially-crafted message to execute arbitrary code on the affected systems. This impacts all NMM clients including each client within a cluster.
EMC NetWorker Module for Microsoft Applications Information Disclosure Vulnerability (CVE-2012-2284)
CVSS v2 Base Score: 6.8 (AV:L/AC:L/Au:S/C:C/I:C/A:C)
When installing or upgrading EMC NetWorker Module for Microsoft Applications on a Microsoft Exchange Server, sensitive administrator credentials are visible in clear text after completion of the install/upgrade. This will occur regardless of successful or failed installations.
NOTE: This vulnerability only affects NMM when using Exchange Server.
The following EMC NMM products contain a resolution for these issues:
EMC NetWorker Module for Microsoft Applications 2.3 build 122 and later
EMC NetWorker Module for Microsoft Applications 2.4 build 375 and later
For customers using Microsoft Exchange Server who are impacted by the Information Disclosure Vulnerability (CVE-2012-2284), the above fixed builds will not expose sensitive credentials in new installations and subsequent upgrades. For existing Exchange installations, customers must refer to EMC Knowledgebase solution esg130356 for additional mitigation steps. EMC strongly recommends all customers upgrade to above builds on all NMM clients. Link to Remedies: Registered EMC Online Support customers can download software from Online Support.
