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

At least one password is stored in the registry by the client software for the IBM iSeries system.

Description

The client software for the IBM iSeries system can automatically connect to an iSeries system without prompting for user credentials.
It does so by storing a default user and its associated password in the registry. The password is protected by a weak encoding algorithm and a known key. A remote attacker can exploit this by accessing the encoded password value in the registry, allowing the attacker to recover the password in plaintext.

Solution

Upgrade to IBM iSeries version 7.1 service pack SI60523 or later.
