{"schemaVersion":3,"id":"CVE-2019-4552","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.
