pg_read_binary_file_blocks 缺少初始用户权限校验,普通用户可读取 relation 文件块
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。
