修复Oracle TNS 监听器远程中毒漏洞
1.1 修改监听文件
如何快速找到listener.ora ？
cmd输入tnsping localhost
修改配置文件，路径以自己的实际路径为准，我都在D盘
listener.ora内容如下：
#listener.ora Network Configuration File: D:\home\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
#Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\home\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = “EXTPROC_DLLS=ONLY:D:\home\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll”)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = D:\home\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = IP)(PORT = 1521))
)
)
ADR_BASE_LISTENER = D:\home\Administrator
#单实例只需要新增下面这一行就OK
VALID_NODE_CHECKING_REGISTRATION_LISTENER=1
然后重启监听就可以了
