Summary
Red Hat Security Advisory: Red Hat JBoss Enterprise Application Platform 7.0 security update
Severity
Moderate
Notes
Topic: A security update is now available for Red Hat JBoss Enterprise Application Platform 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. [Updated 6th November 2017] Previously, this erratum was marked as having a security impact of Critical. This was incorrect; Red Hat JBoss Enterprise Application Platform 7 was affected with a security impact of Moderate. This advisory has been updated to that effect.
Details: Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server. This asynchronous patch is a security update for lucene package in Red Hat JBoss Enterprise Application Platform 7.0.8 Security Fix(es): * It was found that Apache Lucene would accept an object from an unauthenticated user that could be manipulated through subsequent post requests. An attacker could use this flaw to assemble an object that could permit execution of arbitrary code if the server enabled Apache Solr's Config API. (CVE-2017-12629) For more information regarding CVE-2017-12629, see the article linked in the references section.

However, it does ship the vulnerable Lucene class in a dependency to another component. Customers who reuse the lucene-queryparser jar in their applications may be vulnerable to the External Entity Expansion aspect of this flaw. This will be patched in a forthcoming release.\n\nRed Hat JBoss Fuse is not affected by this flaw, as it does not use the vulnerable functionality of either aspect of this flaw. Fuse customers who may be running external Solr servers, while not affected from the Fuse side, are advised to secure their Solr servers as recommended in the mitigation provided.\n\nThe following products ship only the Lucene components relevant to this flaw, and are not vulnerable to the second portion of the vulnerability, the code execution exploit. As such, the impact of this flaw has been determined to be Moderate for these respective products:\nRed Hat JBoss Data Grid 7 \nRed Hat Enterprise Linux 6\nRed Hat Software Collections 2.4\n\nThis issue did not affect the versions of lucene as shipped with Red Hat Enterprise Linux 5.\n\nThis issue does not affect Elasticsearch as shipped in OpenShift Container Platform.",

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.
