tog-pegasus in OpenGroup Pegasus 2.7.0 on Red Hat Enterprise Linux (RHEL) 5, Fedora 9, and Fedora 10 does not log failed authentication attempts to the OpenPegasus CIM server, which makes it easier for remote attackers to avoid detection of password guessing attacks.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2008-1001 advisory.

    [2.7.0-2.0.1.el5_2.1]
    - Added pegasus-enterprise.patch to allow detection of enterprise-release

    [2.7.0-2.el5_2.1]
    - Fix local-or-remote-auth patch and enhance PAM security settings       Resolves: #471370

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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)

Updated tog-pegasus packages that fix security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The tog-pegasus packages provide OpenPegasus Web-Based Enterprise Management (WBEM) services. WBEM is a platform and resource independent Distributed Management Task Force (DMTF) standard that defines a common information model and communication protocol for monitoring and controlling resources.

Red Hat defines additional security enhancements for OpenGroup Pegasus WBEM services in addition to those defined by the upstream OpenGroup Pegasus release. For details regarding these enhancements, refer to the file 'README.RedHat.Security', included in the Red Hat tog-pegasus package.

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 as described in README.RedHat.Security. An attacker able to authenticate using a valid user account could use this flaw to send requests to WBEM services. (CVE-2008-4313)

Failed authentication attempts against the OpenPegasus CIM server were not logged to the system log as documented in README.RedHat.Security.
