一、 介绍
ASPCMS是由武汉上谷网络科技有限公司基于ASP+Access(sql2000)开发并完全开源的一套建站系统,主要面向企业进行快速的建造简洁,高效,易用,安全的公司企业网站,一般的开发人员就能够使用本系统以最低的成本、最少的人力投入在最短的时间内架设一个功能齐全、性能优异的公司企业网站。说的挺好啊,Google了一下还没有人发过它的高危漏洞,转来转去也就是一个XSS,不过还倒是不少网站使用着这套CMS
二、 默认缺陷
最大的缺陷莫过于默认的东西的,这个ASPCMS默认的管理员是admin,密码是123456,默认的access数据库是AspCms_datadata.asp,导致直接在网站前台“客户反馈”――“在线留言”里面就可以直接往数据库插入一句话的shell了。http://www.2cto.com/gbook/
直接插一句话,连接数据库拿http://www.2cto.com/AspCms_data/data.asp。
三、 框架钓鱼
B0mbErM@n发的AspCms v1.1元旦版XSS漏洞是在产品搜索的地方,这个地方除了欺骗管理员之外,还存在一种攻击方法就是使用iframe语句来进行框架调鱼,其实也就是XSS的一种利用方法而已了,如:
五、 后台拿webshell
在“风格模板管理”-“添加模板”的地方直接添加一个文件名称为asp或aspx后缀的文件,文件内容为webshell的代码即可。
还有就是使用FCK编辑器了,不过这个编辑器是要登录后台之后才能上传东西。地址如下:

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.

MySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.

The relationship between SQL and MySQL is the relationship between standard languages and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
