CVE-2020-9488
moderate severity
Vulnerable versions: < 2.13.2
Patched version: 2.13.2
Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender.

CVE-2019-2692
moderate severity
Vulnerable versions: < 8.0.16
Patched version: 8.0.16
Vulnerability in the MySQL Connectors component of Oracle MySQL (subcomponent: Connector/J). Supported versions that are affected are 8.0.15 and prior. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Connectors executes to compromise MySQL Connectors. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL Connectors.

CVE-2019-17571
moderate severity
Vulnerable versions: >= 1.2, <= 1.2.27
Patched version: No fix
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
CVE-2019-17571
中度严重程度
易受攻击的版本：>=1.2，<=1.2.27
修补版本：无修复
log4j1.2中包含一个SocketServer类，该类易受不可信数据反序列化的攻击，当监听日志数据的不可信网络流量时，该类与反序列化小工具结合使用，可远程执行任意代码。这会影响到1.2到1.2.17的Log4j版本。
