Multiple vulnerabilities in XStream that is used by IBM InfoSphere Information Server were addressed.
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.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/198619 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)
CVEID:CVE-2021-21350
**DESCRIPTION:**XStream could allow a remote attacker to execute arbitrary code on the system, 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 execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/198627 for the current score.
