Exploitability

CWE

KEV
KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

[{'type': 'paragraph', 'content': 'Web Ofisi Firma Rehberi version 1 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting malicious SQL code through specific GET parameters.'}, {'type': 'paragraph', 'content': "Attackers can exploit the 'il', 'kat', or 'kelime' parameters in requests to extract sensitive information from the database or perform time-based blind SQL injection attacks, which can reveal data without direct error messages."}] [2]

Impact Analysis

This vulnerability can allow attackers to access sensitive database information without authentication, potentially exposing confidential data.

It can also enable attackers to perform time-based blind SQL injection attacks, which may lead to unauthorized data extraction or manipulation.

The CVSS v3.1 score of 8.2 indicates a high severity impact, with high confidentiality impact and low integrity impact, meaning sensitive data confidentiality is at significant risk.

Detection Guidance

[{'type': 'paragraph', 'content': 'This SQL injection vulnerability can be detected by sending specially crafted HTTP GET requests to the vulnerable endpoint and observing the responses or delays caused by time-based blind SQL injection payloads.'}, {'type': 'paragraph', 'content': "For example, you can test the parameters 'il', 'kat', and 'kelime' in the URL 'firmalar.html' by injecting payloads such as: 0'XOR(if(now()=sysdate(),sleep(0),0))XOR'Z"}, {'type': 'paragraph', 'content': 'A sample test command using curl might be:'}, {'type': 'list_item', 'content': 'curl "http://[TARGET]/firmalar.html?il=0\'XOR(if(now()=sysdate(),sleep(5),0))XOR\'Z&kat=&kelime=&siralama=yeni"'}, {'type': 'paragraph', 'content': 'If the server response is delayed by the sleep time (e.g., 5 seconds), it indicates the presence of a time-based blind SQL injection vulnerability.'}] [2]
