CVE-2026-111440 (GCVE-0-2026-111440)

Vulnerability from cvelistv5 – Published: 2026-10-19 03:55 – Updated: 2026-10-19 17:39

Title

JDBC LogFactory 任意类加载/构造导致潜在 RCE

Summary

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。

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
