Description

Scientific Linux defines additional security enhancements for OpenGroup Pegasus WBEM services in addition to those defined by the upstream OpenGroup Pegasus release.

After re-basing to version 2.7.0 of the OpenGroup Pegasus code, these additional security enhancements were no longer being applied. As a consequence, access to OpenPegasus WBEM services was not restricted to the dedicated users. An attacker able to authenticate using a valid user account could use this flaw to send requests to WBEM services. (CVE-2008-4313)

Note: default SELinux policy prevents tog-pegasus from modifying system files. This flaw's impact depends on whether or not tog-pegasus is confined by SELinux, and on any additional CMPI providers installed and enabled on a particular system.

Failed authentication attempts against the OpenPegasus CIM server were not logged to the system log. An attacker could use this flaw to perform password guessing attacks against a user account without leaving traces in the system log. (CVE-2008-4315)
