CVE-2020-2934Network attack vector

Unauthenticated data modification and disclosure

Published Apr 15, 2020 · Updated Sep 27, 2024

Data exposure and modification in affected Oracle WebLogic Server releases allow remote attackers to read and alter application data via SQL. Oracle identifies the vulnerable locus only as Datasource (MySQL Connector) and has not disclosed the defective class, method, or validation operation. Exploitation requires network access over SQL and interaction by another person; successful attacks can also partially interrupt WebLogic Server.
