CVE-2025-21558Network attack vector

Authenticated unauthorized data read and modification

Published Jan 21, 2025 · Updated Feb 4, 2025

Incorrect authorization in Oracle Primavera P6 EPPM Web Access allows remote authenticated users to read or modify accessible project data. Oracle identifies the affected locus only as Web Access and has not disclosed the request, authorization decision, or operation that mishandles untrusted input. Exploitation requires a low-privileged HTTP session and another person's interaction, and it permits reading a subset of accessible data plus updating, inserting, or deleting some accessible data.
