Security Bulletin: Multiple vulnerabilites affect IBM Engineering Test Management product due to XStream

Vulnerability Details

CVEID:   CVE-2021-21342
DESCRIPTION:   XStream is vulnerable to server-side request forgery, caused by a flaw when processing stream at unmarshalling time. By manipulating the processed input stream and replace or inject objects, an attacker could exploit this vulnerability to conduct SSRF attack o access data streams from an arbitrary URL referencing a resource in an intranet or the local host.
