Description
This security bulletin contains information about 1 vulnerability.
1) Information disclosure (CVE-ID: CVE-2019-12086)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the mysql-connector-java jar in the classpath. A remote attacker can send a specially crafted JSON message and read arbitrary local files on the server due to the missing "com.mysql.cj.jdbc.admin.MiniAdmin" validation.
