CVE-2020-2799Network attack vector

Low-privileged modification of critical accessible data

Published Apr 15, 2020 · Updated Sep 30, 2024

Integrity flaw in the GraalVM Compiler in Oracle GraalVM Enterprise Edition 19.3.1 and 20.0.0 allows remote authenticated users to alter data. Oracle has not published the compiler locus or the operation it performs incorrectly on attacker-controlled input. Exploitation requires low privileges, network access over one of multiple protocols, and high attack complexity; it can create, delete, or modify critical or otherwise accessible data.
