CVE-2019-17634Network attack vector

Script execution via malicious heap dump report

Published Jan 17, 2020 · Updated Aug 5, 2024

Cross-site scripting in Eclipse Memory Analyzer 1.9.1 and earlier allows attackers to execute script via a malicious heap dump HTML report. The report generator renders attacker-controlled heap-dump content into generated HTML, and script executes when the report is opened in Memory Analyzer or a web browser. Exploitation requires a user to obtain and open the malicious dump, generate the report, and then open it; the documented consequence is local code execution.
