Vulnerability Details

CVEID: CVE-2019-4586
DESCRIPTION: IBM InfoSphere Information Server could allow a remote attacker to

to visit a specially-crafted Web site, a remote attacker could exploit this
vulnerability to spoof the URL displayed to redirect a user to a malicious Web
site that would appear to be trusted. This could allow the attacker to obtain
highly sensitive information or conduct further attacks against the victim.
