Vulnerability Information

Severity: Critical
Vulnerability Published: 2021-07-20
Patch Published: 2021-07-20
CVE [?]: CVE-2020-2555, CVE-2021-2358
CPE [?]: cpe:/a:oracle:access_manager, cpe:/a:oracle:fusion_middleware

Synopsis

The remote host has a Single Sign On (SSO) application installed that is affected by multiple vulnerabilities.

Description

The version of Oracle Access Manager installed on the remote host is affected by the following vulnerabilities as noted in the July 2021 CPU advisory : - Vulnerability in the Oracle Access Manager product of Oracle Fusion Middleware (component: Rest interfaces for Access Mgr). The supported version that is affected is 11.1.2.3.0. Easily exploitable vulnerability allows high privileged attacker with network access via HTTPS to compromise Oracle Access Manager. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Access Manager accessible data. (CVE-2021-2358)

- Vulnerability in the Oracle Access Manager product of Oracle Fusion Middleware (component: Installation Component (Oracle Coherence)). The supported version that is affected is 11.1.2.3.0. Difficult to exploit vulnerability allows high privileged attacker with access to the physical communication segment attached to the hardware where the Oracle Access Manager executes to compromise Oracle Access Manager. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Access Manager accessible data as well as unauthorized read access to a subset of Oracle Access Manager accessible data. (CVE-2020-2555)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patches according to the July 2021 Oracle Critical Patch Update advisory.
