Summary
Red Hat Security Advisory: mod_cluster-native security update
Severity
Important
Notes
Topic: An update for the Native components for JBoss Enterprise Application Platform 5.1.2 that fixes one security issue is now available from the Red Hat Customer Portal. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Details: Part of the Native components for JBoss Enterprise Application Platform is mod_cluster, an Apache HTTP Server (httpd) based load balancer. Like mod_jk, it uses a communication channel to forward requests from httpd to an application server node. It was found that mod_cluster allowed worker nodes to register on any virtual host (vhost), regardless of the security constraints applied to other vhosts. In a typical environment, there will be one vhost configured internally for worker nodes, and another configured externally for serving content. A remote attacker could use this flaw to register an attacker-controlled worker node via an external vhost that is not configured to apply security constraints, then use that worker node to serve malicious content, intercept credentials, and hijack user sessions. (CVE-2011-4608) All users of JBoss Enterprise Application Platform 5.1.2 as provided from the Red Hat Customer Portal are advised to apply this update. Refer to the Solution section for installation instructions.

CVE-2011-4608

mod_cluster in JBoss Enterprise Application Platform 5.1.2 for Red Hat Linux allows worker nodes to register with arbitrary virtual hosts, which allows remote attackers to bypass intended access restrictions and provide malicious content, hijack sessions, and steal credentials by registering from an external vhost that does not enforce security constraints.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
