Red Hat Administration Server is an HTTP agent that provides management
features for Red Hat Directory Server, an LDAPv3 compliant server.
A shell command injection flaw was discovered in the Red Hat Administration
Server replication monitor CGI script used by Red Hat Directory Server 8.0.
An attacker with access to the replication monitor web page could execute
arbitrary shell commands with the privileges of the Administration Server.
Please Note: by default, the Red Hat Administration Server is run as the
unprivileged user, "nobody". (CVE-2008-0892)
It was discovered that the Red Hat Administration Server did to properly
restrict access to CGI scripts. An unauthenticated remote user with access
to the TCP port used by the Administration Server could access information
or perform certain tasks that should have been restricted to Directory
Server administrative users. Please note: by default the Red Hat
Administration Server uses port 9830, although this can be changed by the
Red Hat Directory Server administrator. (CVE-2008-0893)
In combination, these two flaws allowed an unauthenticated remote attacker
able to access the Red Hat Administration Server TCP port to run arbitrary
code as the user "nobody".
All users of Red Hat Directory Server should upgrade to this updated
package, which addresses these vulnerabilities.
