说明:
直接在URL后面加单引号,要求单引号没有被过滤(gpc=off)且服务器默认返回错误信息。
Eg:
www.xxx.com/news.php?id=149′
2、错误参数值爆路径
说明:
将要提交的参数值改成错误值,比如-1。单引号被过滤时不妨试试。
Eg:
www.xxx.com/researcharchive.php?id=-1
3、Google爆路径
说明:
结合关键字和site语法搜索出错页面的网页快照,常见关键字有warning和fatal error。注意,如果目标站点是二级域名,site接的是其对应的顶级域名,这样得到的信息要多得多。
Eg:
Site:xxx.edu.tw warning
Site:xxx.com.tw “fatal error”
4、测试文件爆路径
说明:
很多网站的根目录下都存在测试文件,脚本代码通常都是phpinfo()。
Eg:
www.xxx.com/test.php
www.xxx.com/ceshi.php
www.xxx.com/info.php
www.xxx.com/phpinfo.php
www.xxx.com/php_info.php
www.xxx.com/1.php
5、phpmyadmin爆路径
说明:
一旦找到phpmyadmin的管理页面,再访问该目录下的某些特定文件,就很有可能爆出物理路径。至于phpmyadmin的地址可以用wwwscan这类的工具去扫,也可以选择google。PS:有些BT网站会写成phpMyAdmin。
Eg:
www.xxx.cn/phpmyadmin/themes/darkblue_orange/layout.inc.php
www.xxx.cn/phpmyadmin/libraries/select_lang.lib.php
www.xxx.cn/phpmyadmin/index.php?lang[]=1
6、配置文件找路径
说明:
如果注入点有文件读取权限,就可以手工load_file或工具读取配置文件,再从中寻找路径信息(一般在文件末尾)。各平台下Web服务器和PHP的配置文件默认路径可以上网查,这里列举常见的几个。
Eg:
Windows:
c:\windows\php.ini php配置文件
c:\windows\system32\inetsrv\MetaBase.xml IIS虚拟主机配置文件
Linux:
/etc/php.ini php配置文件
/etc/httpd/conf.d/php.conf
/etc/httpd/conf/httpd.conf Apache配置文件
/usr/local/apache/conf/httpd.conf
/usr/local/apache2/conf/httpd.conf
/usr/local/apache/conf/extra/httpd-vhosts.conf 虚拟目录配置文件
7、nginx文件类型错误解析爆路径
说明:
这是昨天无意中发现的方法,当然要求Web服务器是nginx,且存在文件类型解析漏洞。有时在图片地址后加/x.php,该图片不但会被当作php文件执行,还有可能爆出物理路径。
Eg:
www.xxx.com/top.jpg/x.php
8、其他
其他就是像dedecms、phpwind之类的整站程序爆路径漏洞,比较杂,通用性不强。可以在回帖里反馈此类漏洞,我再做整理。

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
