低危 Oracle Secure Global Desktop 5.3 Web Server 内存错误引用漏洞
CVE编号
CVE-2017-9798利用情况
POC 已公开补丁情况
官方补丁披露时间
2017-09-19漏洞描述
如果可以在用户的.htaccess文件中设置Limit指令，或者如果httpd.conf具有某些错误配置(即Optionsbleed)，则Apache httpd允许远程攻击者从进程内存中读取秘密数据。这会影响 Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27。在尝试读取机密数据时，攻击者会发送未经身份验证的OPTIONS HTTP请求。这是一个UAF的问题，因此并不总是发送秘密数据，具体数据取决于许多因素，包括配置。可以使用server/core.c中的ap_limit_section函数的patch来阻止.htaccess的使用。解决建议
目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载:https://svn.apache.org/viewvc/httpd/httpd/branches/2.4.x/server/core.c?r1=1805223&r2=1807754&pathrev=1807754&view=patchhttps://github.com/hannob/optionsbleedhttps://github.com/apache/httpd/commit/29afdd2550b3d30a8defece2b95ae81edcf66ac9https://blog.fuzzing-project.org/uploads/apache-2.2-optionsbleed-backport.patch受影响软件情况
