CVE-2021-29620Network attack vector

Secret disclosure and SSRF via external DTD processing

Published Jun 23, 2021 · Updated Aug 3, 2024

XXE in Test IO ReportPortal before 5.4.0 allows remote attackers to read service-api secrets or trigger SSRF via JUnit XML import. XunitParseJob used a SAX parser that still accepted external parameter entities and loaded external DTDs from attacker-controlled URIs. The attack requires submission of a crafted JUnit XML launch import; it can disclose files accessible to service-api or make server-side network requests.
