IBM Spectrum Protect Plus hostname Command Injection

critical Nessus Plugin ID 139330
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

A web application running on the remote host is affected by a remote code execution vulnerability.

Description

The IBM Spectrum Protect Plus (SPP) administrative console running on the remote host is affected by a remote command injection vulnerability due to improper validation of user-supplied data when processing a 'set hostname' HTTP request. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request, to execute arbitrary code on the system with root privileges.

Note that this plugin does not flag SPP 10.1.5 build 2218 having the spp-emi-10.1.5-227 RPM package as vulnerable because it partially fixed the vulnerabilities by enabling authentication for URL /emi/api/hostname. A full fix is in spp-emi-10.1.6-21 in SPP 10.1.6 build 1974, which performs additional checking on the hostname parameter in the HTTP request to prevent authenticated command injection.

Also note that the application is reportedly affected by other vulnerabilities; however, this plugin has not tested for those issues.

Solution

Update the IBM Spectrum Protect Plus RPM package spp-emi to 10.1.6-21 or later. That spp-emi package should be in the IBM Spectrum Protect Plus 10.1.6 build 1974.
