CVE-2020-2900Network attack vector

Authenticated partial data disclosure and modification

Published Apr 15, 2020 · Updated Sep 27, 2024

A Tools component flaw in Oracle GraalVM Enterprise Edition 19.3.1 and 20.0.0 allows remote authenticated users to read and modify data. Oracle does not disclose the underlying Tools operation or the inputs that reach it, so the concrete code-level mechanism is unavailable. Exploitation requires low privileges, network access over an unspecified supported protocol, high complexity, and interaction by another user; impact is limited to reading and modifying some accessible data.
