GHSA-CR5J-X763-5676

Vulnerability from github – Published: 2026-10-19 09:32 – Updated: 2026-10-19 09:32

Details

在 openGauss-server的 src/common/backend/utils/adt/genfile.cpp 模块中，内置函数 pg_read_binary_file_blocks() 存在权限校验逻辑缺陷。该函数在入口处仅校验了起始块号（startBlockNum）和块数量（blockCount）的范围，随后直接调用底层文件读取例程 ReadBinaryFileBlocksFirstCall()。该底层例程仅执行了路径规范化检查以及针对 .. 路径遍历和数据目录边界的基本检查，缺失了对调用者数据库权限（如 SELECT 权限）的校验。此外，辅助函数 is_row_data_file() 也仅用于识别文件形态，未包含权限检查。因此，任何拥有普通数据库连接权限的用户，只要能够通过 pg_relation_filepath() 等函数获取到目标表的底层关系文件路径（例如压缩数据的 _compress 文件路径），即可无需具备该表的 SELECT 权限，直接读取表数据的二进制块。此漏洞影响此前3.0.0到6.0.0间的所有版本及补丁版，并在7.0.0-LTS版本修复。修复patch详见：https://gitcode.com/opengauss/openGauss-server/pull/9374。

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.
