linux提权的几点小能力

我其实其实不精晓Linux渗入渗出,会的那丁点的确凡是跟小白学的,尽管学的很菜。 本日小白在群里发了1个英国的虚构主机。很明白php的网站shell没有权限,那么她是怎么拿到打点权限的?反弹连接呗。无非她说,关于Linux不 精晓的人,她个人建议先从vi学起。尽管了,当初她写的1些傻瓜化网站shell偶然1键就能够搞定反弹连接。无非本章只讲,如何用vi来旁注处事器上的 其它网站。

1个实际例子(实际上小白用的体式名目比这个繁冗的繁冗多了,无非这篇我们从最菜的开始讲):
网站目次是:

Default
/var/www/vhosts/XX.gov.uk/httpdocs/cms/assets

履行号令dir回显取得:

Default
1234五六78910111213141五 Building Notice Fee.pdfBuilding Notice Work Flow Process Diagram v2.2 (Pages 1 - 4) 22.01.07.pdfCNC_BN_v27_01_10.pdfFull Plans Fee rev.pdfbullet.gifeditor_box_a.gifeditor_box_b.gifgallery1gallery2imgshow.phpindex.phpiwe_flash.swfsound.midsound.wavsound.wma

ok,这即是欢乐剧的前兆。继续dir /var/www/vhosts/回显取得无数的网站的目次名称,直接以XX.com、XX.uk命名,让负面的垄断未便了很多。
筛选第1个网站:

Default
dir /var/www/vhosts/www.91ri.org /httpdocs/

创举1个迟钝的文件名contact.php
那么下面即是我们的枢纽人物,vi出场的时候了
说鬼话,vi尽管菜,可是参数我依旧没学精晓。委曲看吧

Default
vi /var/www/vhosts/acornworks.com/httpdocs/contact.php

惋惜了,不是MySql的配置文件

Default
1234五六789 "/var/www/vhosts/acornworks.com/httpdocs/contact.php"<r/www/vhosts/acornworks.com/httpdocs/contact.php" [readonly][noeol] <?phpif (!isset($_SESSION)) [4;9H{ [五;9Hsession_start(); [六;9H}$redirect = '';$mailto = 'sales@acornworks.com';$subject = "acornworks.com";if (ereg($_SERVER[HTTP_HOST], $_SERVER[HTTP_REFERER])) [13;9H{# [7Cif ($_SESSION[key] == sha1($_POST[security_code])) [1五;9Hif (1 == 1) [1六;17H{ [17;17H$email_body = ''; [19;17Hforeach ($_POST as $key => $value) [20;2五H{ [21;2五Hif (ereg("field_", $key)) [22;33H{ [23;33H$key = eregi_replace("field_", "", $key); [1;1H [24;1H [?1l > [2J [?47l 8Vim: Error reading input, exiting...Vim: Finished.

回去,继续dir和vi,读到MySql配置文件位置。
下节讲改目次、文件属性或者复制文件


国内上最通用的Linux虚构主机搭建立施是这样的:

Linux垄断琐屑+Apache网站容器+PHP脚+MySQL数据库
1 个处事器上的网站配置新闻明白都储存在Apache的配置文件中。群体Apache会调剂在Linux的这个目次下:/usr/local,其 Apache的conf配置文件也会在Apache的目次下,尽管,也有的Apache配置文件会独自拿进去,放到比如/etc/httpd/conf /httpd.conf这样之处。本日我就拿两则cent os琐屑来阐明1下读取配置文件的相关内容。既然负面老大Mr.Cool做了1篇Linux文章了,为了共同其延续性,我终极仍是把作者名改为。
第 1则是1个电脑学校本人搭建的虚构主机。Apache没有调剂在/usr/local这个目次下,实际上打点员还对Apache做了userdir的权 限设定,也即是说尽管是Linux+Apache的主机,可是无法直接读取虚构主机目次以外的文件夹内容。幸亏exec和system还能用。
这样的话我就用ls号令列目次。
/usr目次翻遍没有找到Apache的事迹。网站的目次是/server
那么我就用ls列/server的目次,着末必然在这里:

Default
ls /server/program

回显:

Default
1234五六7891011121314 apacheaprapr-utilcurlfreetype2gd2ImageMagickjpeg六libxml2mysqlphpproftpdsubversionzlib

是Apache目次,读取conf表面的配置文件:

Default
cat /server/program/apache/conf/extra/httpd-vhosts.conf

取得回显如下(出于隐衷眷注的绳尺已隐藏处置惩罚惩罚):

为什么要看这个配置呢?
起首,既然是虚构主机,那就先要搞鲜亮熟识打听处事器上都有什么网站吧,目次在那边那边。鬼话说,这个处事器的打点员程度不赖,URLrewrite都配置上了 R11; R11;
好吧,人不克不及夸,1夸尾巴繁冗翘公开去,他的网站目次设置的,相等乱。。。
其次,打点员设置了目次权限,无法直接会面其它目次,那么就用system或者exec来履行command line号令,比如ls,再比如。。。

Default
cp -a /xxxx /xxxxxx

直接把网站shell拷贝到指标网站的目次里。。。好峭拔。。。
好了,第2个是广岛大学研讨所的1个处事器
这个大学的处事器仍旧是花了我很多时间去研讨。。。研讨所的目标难道即是让别人花老多时间去研讨么。。。
处事器上PHP有履行command line的权限,也有直接读取其它目次文件的权限,独立处事器,权限较劲宽松。这个大学的处事器上面,我征采遍了,并无找到Apache目次。明白我也没有找到配置文件。
缘由是,我先入为主的以为Apache的配置文件理应在Apache目次下,没有找到Apache目次,自然找不到Apache的配置文件
其 实这是错误的想法,Apache的配置文件定然就在Apache的目次下,真正的conf配置目次被独自安置在:/etc/httpd这个文件夹表面。 VirtualHost的配置大同小异,我就不贴了。尽管了,Apache的log也在这个httpd文件夹下,看着别人还在扫目次,而我已经出去 了。。。。

德国的黑客好可恶。。。
本文没有什么极真个拙劣妙技,无非是1点点个人经历的总结


1些人1直觉得Linux提权是1项拙劣妙技,其实Linux提权其实不泄密。总结其按次,或许繁冗分为五步:

1,失去网站shell
2,具有履行command line权限,并失去Linux的琐屑版本
3,上传与Linux琐屑版本对应的裂痕提权脚本至可写可履行的目次下
4,履行提权脚本和反弹连接脚本
五,远程垄断command line管束机器

本文所采取的实例依旧是广岛大学研讨所的处事器,可是目前为止我并无提权战败,尽管不是1个战败的实例,可是文章的目标在于阐明历程而非阐明结果
广岛大学研讨所的网站处事器架设环境是:
Cent OS + PHP + Apache + PsotgreSQL
尽管这些其实不垂危,我失掉了网站shell,而且创举有exec和system函数的权限,这样就好办多了
起首,读取password文件:

Default
cat /etc/passwd

失掉:

Cent OS 五.4的琐屑简直是2.六.18的内核。可是目前为止没有创举这个RedHat的琐屑有什么裂痕 R11; R11;

传了1个去年的2.六.18的提权脚本到/tmp目次

当心,1般来讲,提权脚本凡是放在/tmp目次,缘由很繁冗,目次繁冗,可写可履行~起名为:2六18.c

好了,提权畴前,这是1个c文件,是不克不及像rb或者pl那样直接脚本履行的,我们要先编译:

Default
gcc -o /tmp/2六18 /tmp/2六18.c

这样就把/tmp/2六18.c编译成了或许履行的文件/tmp/2六18了

此时直接履行这个文件就行了

Default
/tmp/2六18

尽管,回显提示是腐败的

尽管,直接对RedHat揭晓的Linux琐屑版本终止内核提权明白不是明智的决议。我的思路是,查找琐屑中含有裂痕的软件、驱动等,用它们来提权。不幸的是我目前还没战败 R11; R11;

文章总结:提权脚本有两点要当心,gcc号令编译无法编译出脚本定然是琐屑的问题,或许是c脚本本身有问题。假如琐屑无法gcc出可履行的文件,或许在本地或者其它地方gcc进去,然后直接传上来,直接履行
