Summary
Red Hat Security Advisory: JBoss Enterprise SOA Platform 5.3.0 security update
Severity
Important
Notes
Topic: An update for the JBoss Web Services component in JBoss Enterprise SOA Platform 5.3.0 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: JBoss Enterprise SOA Platform is the next-generation ESB and business process automation infrastructure. JBoss Enterprise SOA Platform allows IT to leverage existing (MoM and EAI), modern (SOA and BPM-Rules), and future (EDA and CEP) integration methodologies to dramatically improve business process execution speed and quality. An attack technique was found against the W3C XML Encryption Standard when block ciphers were used in cipher-block chaining (CBC) mode. A remote attacker could use this flaw to conduct chosen-ciphertext attacks, leading to the recovery of the entire plain text of a particular cryptogram by examining the differences between SOAP (Simple Object Access Protocol) responses sent from JBoss Web Services. (CVE-2011-1096) Red Hat would like to thank Juraj Somorovsky of Ruhr-University Bochum for reporting this issue. Note: Manual action is required to apply this update. The CVE-2011-1096 issue is an attack on the WS-Security standard itself. Using new Galois/Counter Mode (GCM) based algorithms for WS-Security encryption is the W3C suggested way of dealing with this issue. The WS-SecurityPolicy specification has not yet been updated to include the new algorithms. Consequently, Apache CXF independently added support for such GCM based algorithms through AlgorithmSuites called "Basic128GCM", "Basic192GCM", and "Basic256GCM" in the namespace "http://cxf.apache.org/custom/security-policy". To apply these policies to your applications that use WS-Security encryption, specify them in the application's WSDL file. Refer to Red Hat Bugzilla bug 681916 for an example. All users of JBoss Enterprise SOA Platform 5.3.0 as provided from the Red Hat Customer Portal are advised to install this update.

CVE-2011-1096

The W3C XML Encryption Standard, as used in the JBoss Web Services (JBossWS) component in JBoss Enterprise Portal Platform before 5.2.2 and other products, when using block ciphers in cipher-block chaining (CBC) mode, allows remote attackers to obtain plaintext data via a chosen-ciphertext attack on SOAP responses, aka "character encoding pattern attack."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

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.
Vulnerability timeline

Sightings and recorded dates, grouped by day · UTC

JSON
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.
