Mike Kienenberger commented on TRINIDAD-2542:
---------------------------------------------
The "information disclosure vulnerability" was a cut&paste error. It should
be "deserialization security vulnerability" -- I'll see what I can do to get
that corrected.
> CVE-2016-5019: MyFaces Trinidad view state deserialization security
> vulnerability
> ---------------------------------------------------------------------------------
>
> Key: TRINIDAD-2542
> URL: https://issues.apache.org/jira/browse/TRINIDAD-2542
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Components
> Affects Versions: 1.2.14-core , 1.0.13-core , 2.0.1-core, 2.1.1-core
> Reporter: Mike Kienenberger
> Assignee: Leonardo Uribe
> Priority: Critical
> Fix For: 1.2.15-core , 2.0.2-core, 2.1.2-core
>
>
> Trinidad’s CoreResponseStateManager both reads and writes view state strings
> using ObjectInputStream/ObjectOutputStream directly. By doing so, Trinidad
> bypasses the view state security features provided by the JSF implementations
> - ie. the view state is not encrypted and is not MAC’ed.
> Trinidad’s CoreResponseStateManager will blindly deserialize untrusted view
> state strings, which makes Trinidad-based applications vulnerable to
> deserialization attacks.
