"The version of EMC RSA Authentication Manager running on the remote
host is prior to 8.3 Patch 1 (8.3.0.1). It is, therefore affected by
the following vulnerabilities:

  - A flaw exists with the Security Console due to improper parsing of
    XML data. An authenticated remote attacker, with a specifically
    crafted XML data, could potentially cause a denial of service or
    access sensitive information. (CVE-2018-1247)

  - A flaw exists with the Security Console, Operation Console and
    Self-Service Console due to improper sanitization of input when
    handling specially crafted requests. A context-dependent attacker
    could inject custom http headers, potentially poisoning the http
    cache and redirecting users. (CVE-2018-1248)");
