Detailsinfo

A vulnerability classified as problematic has been found in EMC NetWorker up to 8.0.4.4/8.1.3.5/8.2.2.1/9.0. This affects an unknown part of the component RPC Authentication Message Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

EMC NetWorker before 8.0.4.5, 8.1.x before 8.1.3.6, 8.2.x before 8.2.2.2, and 9.0 before build 407 allows remote attackers to cause a denial of service (process outage) via malformed RPC authentication messages.

The weakness was published 12/05/2015 (Website). The advisory is shared at seclists.org. This vulnerability is uniquely identified as CVE-2015-6849 since 09/10/2015. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 87309 (EMC NetWorker < 8.0.4.4 / 8.1.x < 8.1.3.6 / 8.2.x < 8.2.2.2 / 9.0.x < 9.0.0.2 RPC Authentication DoS), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context l.

Upgrading to version 8.0.4.5, 8.1.3.6, 8.2.2.2 or 9.0 Build 407 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (87309), SecurityFocus (BID 78519†) and Vulnerability Center (SBV-55515†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
