CVE-2021-2258Network attack vector

Authenticated disclosure and modification of project data

Published Apr 22, 2021 · Updated Sep 26, 2024

An unspecified flaw in Oracle Projects allows remote authenticated users to read and modify critical project data through its HTTP user interface. Oracle identifies the affected component only as User Interface and has not published the specific UI locus or the operation that mishandles authorization. Low-privileged HTTP access is required; affected releases are 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10, and exploitation permits complete read or write access to Oracle Projects data.
