Read/write information from the database.The input provided by an attacker may include characters that could interfere with the SQL syntax and will result in arbitrary SQL queries performed on the database.Īs a result, the risk of an SQL Injection vulnerability is that the attacker could: They do this by first finding a vulnerable user input within a web app and create input content which is often used as the malicious payload to launch this attack.
SQLi is also one of the most well-known web application vulnerabilities with a dedicated chapter in the OWASP Top 10 project and is also a highly chased after vulnerability in bug bounty programs.Ī common SQL injection attack happens when attackers try to insert malicious SQL statements located in an HTTP (or HTTPS) request by changing the current behavior of SQL statements created by the web application. SQL Injection remains one of the most prevalent attacks used by hackers and a serious security threat to both individuals and companies. # perl -u noge]# perl ssdp.What is an SQL injection and how do I prevent this attack? You can add your own table name & column name by editing file called tables.dict & columns.dict. What can we do with create file vuln? we can make a php file as backdoor at the target if we know the directory path. To see if it works or no lets read /tmp/ssdp.txt using load_file function. URL above means we write “Simple SQLi Dumper” into ssdp.txt that locate at /tmp directory. Let’s create some file in /tmp directory. To use load_file you need to convert the /etc/passwd into hexadecimal. It means we can read (load_file) the /etc/passwd file on a target also we can create file at /tmp directory. to inject, we do it manually.Īs you can see at the first time we find magic number you’ll find this line. Why read only? coz this function design just to test if we can read file or no. Now let’s see Read File (read only) & Create File (read only). Column Name string to search: addressįound column with word “address” on table “customer”. # perl -u -d -c noge]# perl -u -d 460store -c address -find I’ll try to search column with keyword “address” it require -c option (column)
Sqli dumper not showing urls how to#
Now i’ll show you how to use -find option (Search Columns Name) Ok i have show you how to find magic number, table, column and dump data the column using SSDp. # perl -u -t -c, noge]# perl -u -t security -c username,password -dump Now we’ll see information inside that column. security(1): user_id,username,password,admin,last_loginĪha! we got column called “username” and “password”. # perl -u -t noge]# perl -u -t security -column Let’s see column from table called “security”. That is the list of all table in database() Now we use URL that include “c0li” string on it to find table & column. We can see the database information and operation system too. Our magic number is 1 and it will replace with “c0li” string. Null column used for execute our SQL query. | -log file name to save ssdp data (default: ssdp.log) |įirst of all we have to find null column (magic number). | -start row number to begin dumping data | | -f max field to get magic number (default: 123) | | -c column_name (example: id,user,pass,email) | | -d this option should not be used (default: | | -e sql injection end tag (default: “–”) | | -u target with id parameter or sqli url with c0li string | SSDp is an usefull penetration tool to find bugs, errors or vulnerabilities in MySQL database. WE ARE NOT RESPONSIBLE OF ANY DAMAGE AND IMPROPERLY USE OF THIS TOOL. USE THIS TOOL FOR EDUCATION PURPOSE ONLY.
