Apache Tika 1.13 Code Execution

Apache Tika 1.13 Code Execution
Posted Nov 10, 2016
Authored by Pierre Ernst

Apache Tika wraps the jmatio parser to handle MATLAB files. The parser uses native deserialization on serialized Java objects embedded in MATLAB files. A malicious user could inject arbitrary code into a MATLAB file that would be executed when the object is deserialized. Versions 1.6 through 1.13 are affected.
