mod_perl is vulnerable to information disclosure. It was discovered that Red Hat Network Satellite Server shipped with an XML-RPC script, manzier.pxt, which had a single hard-coded authentication key. A remote attacker who is able to connect to the Satellite Server XML-RPC service could use this flaw to obtain limited information about Satellite Server users, such as login names, associated email addresses, internal user IDs, and partial information about entitlements.
