Description

在 openGauss-connector-jdbc 的 pgjdbc/src/main/java/org/postgresql/log/LogFactory.java 中,LogFactory 根据 JDBC 连接参数中的 logger 类名调用 Class.forName 加载类后,直接反射调用以 String 为参数的构造函数,再转换为 Log。缺少 asSubclass(Log.class) 校验,非 Log 实现类也会在类型检查前被实例化。因此,当攻击者可控制 JDBC URL 或连接属性中的 logger 类名,且客户端 classpath 中存在可被加载的类时,可能在客户端触发非预期的类加载与构造副作用。 此漏洞自 JDBC 1.1.0引入,影响 1.1.0 及之后的 2.x、3.x、5.x、6.x 各版本及补丁(含 6.0.0 分支最新 6.0.6),以及 7.0.0-RC1、7.0.0-RC2、7.0.0-RC3,并在 7.0.0-LTS 版本修复。修复在 Class.forName 之后先执行 asSubclass(Log.class),仅允许 Log 子类进入构造。修复pr见https://gitcode.com/opengauss/openGauss-connector-jdbc/pull/423。
