Dell NetVault Backup 10.0.x < 10.0.5 RCE

Critical Nessus Plugin ID 84006

Synopsis

The remote backup server is affected by a remote code execution vulnerability.

Description

The Dell NetVault Backup installed on the remote host is version 10.0.x prior to 10.0.5. It is, therefore, affected by the following vulnerabilities :

- A flaw exists in the libnv6 module due to an integer overflow condition. A remote attacker, by manipulating a serialized object's template string specifiers, can exploit this to cause an overflow, resulting in a denial of service or the execution of arbitrary code.
(CVE-2015-4067)

- A denial of service vulnerability exists in nvpmgr.exe related to the handling of specially crafted strings, which a remote attacker can exploit to cause crash.
(CVE-2015-5696)

Note that both of these issues may be caused by the same underlying flaw and are both fixed by upgrading to the version specified by Dell.

Solution

Upgrade to Dell NetVault Backup 10.0.5 or later.
