Java vulnerability analysis and mitigation
Overview
Apache Heron versions 0.20.2-incubating, 0.20.1-incubating, and v-0.20.0-incubating contain a remote code execution vulnerability due to improper YAML parser configuration that allows instantiation of arbitrary types (CWE-502: Deserialization of Untrusted Data). The vulnerability was disclosed in April 2020 (NVD, MITRE).
Technical details
The vulnerability stems from a misconfiguration in the YAML parser implementation that fails to prevent the instantiation of arbitrary types. This security flaw is classified as CWE-502 (Deserialization of Untrusted Data), which can lead to remote code execution capabilities (NVD).
Impact
The vulnerability allows remote attackers to execute arbitrary code through deserialization of untrusted data, potentially leading to complete system compromise (NVD).
Mitigation and workarounds
Users should upgrade to a patched version of Apache Heron that properly configures the YAML parser to prevent arbitrary type instantiation (Apache List).
