descriptionThe version of Oracle Access Manager installed on the remote host is affected by the following vulnerabilities as noted in the April 2020 CPU advisory : - An unspecified vulnerability exists in the Authentication Engine component of Oracle Fusion Middleware subcomponent Oracle Access Manager. An authenticated, remote attacker can exploit this, via HTTP, to update, insert, or delete some of Oracle Access Manager accessible data, as well as unauthorized read to a subset of Oracle Access Manager accessible data. (CVE-2020-2740) - An unspecified vulnerability exists in the Federation component of Oracle Fusion Middleware subcomponent Oracle Access Manager. An unauthenticated, remote attacker can exploit this, via HTTP, to cause a partial denial of service (DoS) of Oracle Access Manager. (CVE-2020-2745) - An unspecified vulnerability exists in the SSO Engine component of Oracle Fusion Middleware subcomponent Oracle Access Manager. An authenticated, remote attacker can exploit this, via HTTP, to update, insert, or delete some of Oracle Access Manager accessible data, as well as unauthorized read to a subset of Oracle Access Manager accessible data.
