Oracle 9i应用服务器基于Apache Web服务器，支持SOAP、PL/SQL、XSQL、JSP等环境。

Oracle 9i应用服务器使用的DAV模块在记录错误信息时存在格式串错误，远程攻击者可以利用这个漏洞构建恶意请求破坏Oralce进程的堆栈结构，可能以\’\’Oralce\’\’进程权限在系统上执行任意指令。攻击者通过构建恶意格式串发送给服务器，可导致覆盖堆栈中任意地址，可能以Oralce进程权限在系统上执行任意指令。成功利用此漏洞可以获得权限是在Linux/unix系统上为\”Oracle\”权限，而在Windows系统下Local System权限。

临时解决方法：

如果您不能立刻安装补丁或者升级，CNNVD建议您采取以下措施以降低威胁：

* 编辑ORACLE_HOME/Apache/oradav/conf目录下的moddav.conf文件：

更改如下行：

DAV on

为

DAV off

然后关闭文件，结果配置文件应该如下所示：

Load/Module ORACLE_HOME/Apache/oradav/lib/mod_oradav.so

#This is needed by mod_oradav to manage locks on WebDAV activity

#against a local file system and contains lock information about all

#WebDAV file resources.

DAVLockDB ORACLE_HOME/Apache/oradav/var/DAVLock

DAV off

#For extra security, enable the ForceType directive below.

#ForceType is used to prevent any scripts (jsp,php,…)

#from being run. Since this is a public location and anyone

#could upload a script and then execute it we need to be

#careful we don’t want it exploited. To preserve

#mime types of files but to still protect against executables

#see HTTP Admin Documentation on mod_oradav regarding ORAGetSource.

#

#ForceType text/plain
