Summary
PowSyBl Core allows deserialization of untrusted SparseMatrix data
Details

Impact

What kind of vulnerability is it? Who is impacted?

This is a disclosure for a security vulnerability in the SparseMatrix class. The vulnerability is a deserialization issue that can lead to a wide range of privilege escalations depending on the circumstances. The problematic area is the read method of the SparseMatrix class. This method takes in an InputStream and returns a SparseMatrix object. We consider this to be a method that can be exposed to untrusted input in at least two use cases: - A user can adopt this method in an application where users can submit an InputStream and the application parses it into a SparseMatrix. This can be a multi-tenant application that hosts many different users perhaps with different privilege levels. - A user adopts the method for a local tool but receives the InputStream from external sources.

Am I impacted?

You are vulnerable if you import non-controlled serialized SparseMatrix objects.

Patches

com.powsybl:powsybl-math:6.7.2 and higher

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

Do not use SparseMatrix deserialization (SparseMatrix.read(...) methods).
