Features: * Easily updatable CSV-format checks database * Output reports in plain text or HTML * Available HTTP versions automatic switching * Generic as well as specific server software checks * SSL support (through libnet-ssleay-perl) * Proxy support (with authentication) * Cookies support ## Scan examples ### Scan a single port ```bash nikto -url http://10.10.236.92:1234 ``` or ```bash nikto -url http://10.10.236.92 -p 1234 ``` ### Scan multiple ports ```bash nikto -url http://$TARGET_IP -p 80,8000,8080 ``` ### Scan with authentication (-id) ```bash nikto -url http://10.10.236.92:1234/manager/html -id bob:bubbles ``` ## Scan tuning Test types can be controlled at an individual level by specifying their identifier to the `-T` (`-Tuning`) option. In the default mode, if `-T` is invoked only the test type(s) specified will be executed. For example, only the tests for "Remote file retrieval" and "Command execution" can performed against the target: ```bash nikto -h 192.168.0.1 -T 58 ``` If an "x" is passed to `-T` then this will negate all tests of types following the x. This is useful where a test may check several different types of exploit. For example: ```bash nikto -h 192.168.0.1 -T 58xb ``` The valid tuning options are: * 0 - **File Upload**. Exploits which allow a file to be uploaded to the target server. * 1 - **Interesting File / Seen in logs**. An unknown but suspicious file or attack that has been seen in web server logs (note: if you have information regarding any of these attacks, please contact CIRT, Inc.). * 2 - **Misconfiguration / Default File**. Default files or files which have been misconfigured in some manner. This could be documentation, or a resource which should be password protected. * 3 - **Information Disclosure**. A resource which reveals information about the target. This could be a file system path or account name. * 4 - **Injection (XSS/Script/HTML)**. Any manner of injection, including cross site scripting (XSS) or content (HTML). This does not include command injection. * 5 - **Remote File Retrieval** - Inside Web Root. Resource allows remote users to retrieve unauthorized files from within the web server's root directory. * 6 - **Denial of Service**. Resource allows a denial of service against the target application, web server or host (note: no intentional DoS attacks are attempted). * 7 - **Remote File Retrieval** - Server Wide. Resource allows remote users to retrieve unauthorized files from anywhere on the target. * 8 - **Command Execution / Remote Shell**. Resource allows the user to execute a system command or spawn a remote shell. * 9 - **SQL Injection**. Any type of attack which allows SQL to be executed against a database. * a - **Authentication Bypass**. Allows client to access a resource it should not be allowed to access. * b - **Software Identification**. Installed software or program could be positively identified. * c - **Remote source inclusion**. Software allows remote inclusion of source code. * d - **WebService**. Web service endpoints or related functionality. * e - **Administrative Console**. Administrative interfaces or consoles. * f - **XML Injection**. XML-related injection vulnerabilities. * x - **Reverse Tuning Options**. Perform exclusion of the specified tuning type instead of inclusion of the specified tuning type. ## Usage information
