CVE-2020-14900 (GCVE-0-2020-14900)

Vulnerability from cvelistv5 – Published: 2020-10-21 14:04 – Updated: 2024-09-26 20:00

Summary

Vulnerability in the Oracle Application Express Group Calendar component of Oracle Database Server. The supported version that is affected is Prior to 20.2. Easily exploitable vulnerability allows low privileged attacker having Valid User Account privilege with network access via HTTP to compromise Oracle Application Express Group Calendar. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Application Express Group Calendar, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Application Express Group Calendar accessible data as well as unauthorized read access to a subset of Oracle Application Express Group Calendar accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).
