CVE-2020-2875Network attack vector

Data read and modification via undisclosed input flaw

Published Apr 15, 2020 · Updated Sep 27, 2024

Unspecified input handling in Oracle MySQL Connector/J 8.0.14 and earlier and 5.1.48 and earlier allows remote attackers to read and alter data. Oracle identifies Connector/J and the MySQL protocol but has not published the responsible class, method, input, or incorrect operation. Exploitation requires no authentication but has high complexity and requires another person to interact; successful attacks expose or modify only some accessible data and do not interrupt service.
