CVE-2019-4552 (CCN-165960)

Assigned:2019-01-03
Published:2020-10-14
Updated:2020-10-20
Summary:IBM Security Access Manager 9.0.7 and IBM Security Verify Access 10.0.0 are vulnerable to HTTP response splitting attacks. A remote attacker could exploit this vulnerability using specially-crafted URL to cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning, cross-site scripting, and possibly obtain sensitive information. IBM X-Force ID: 165960.
