Description
PHPads 2.0 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the bannerID parameter in click.php3. Attackers can submit crafted bannerID values using SQL comment syntax and functions like extractvalue to extract sensitive database information such as the current database name.

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': "The vulnerability in PHPads 2.0 is an SQL injection flaw found in the 'click.php3' script via the 'bannerID' parameter. This allows unauthenticated attackers to inject arbitrary SQL commands by manipulating the 'bannerID' value in the URL."}, {'type': 'paragraph', 'content': "The application uses the deprecated 'ereg' function without proper input sanitization to process the 'bannerID' parameter, enabling attackers to craft malicious SQL queries."}, {'type': 'paragraph', 'content': "An attacker can exploit this by injecting SQL code that uses functions like 'extractvalue' combined with 'concat' and 'select database()' to extract sensitive information such as the current database name."}] [1]

Impact Analysis

This SQL injection vulnerability can lead to unauthorized access to the database, allowing attackers to extract sensitive information.

Attackers can manipulate SQL queries executed by the application, potentially leading to data leakage or further compromise of the system.

Since the vulnerability is exploitable without authentication, it poses a high risk to the confidentiality and integrity of the data managed by the application.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by identifying instances of the PHPads 2.0 application that use the vulnerable \'click.php3\' script with the \'bannerID\' parameter. One method is to use Google dork queries such as inurl:"click.php3?bannerID=" to locate potentially vulnerable URLs.'}, {'type': 'paragraph', 'content': "To test for the SQL injection, you can attempt to inject a crafted payload into the 'bannerID' parameter that uses MySQL functions like extractvalue to see if the application returns database error messages or extracts database information."}, {'type': 'paragraph', 'content': 'An example of a proof-of-concept URL to test the vulnerability is:'}, {'type': 'list_item', 'content': 'http://server/phpads/click.php3?bannerID=-1/*!50000and*/+/*!50000extractvalue*/(0x0a,/*!50000concat*/(0x0a,0x73337830753a,(/*!50000select*/%20database()),0x3a7333783075))--+-'}, {'type': 'paragraph', 'content': 'If the application responds with database error messages or reveals the current database name, it indicates the presence of the SQL injection vulnerability.'}] [1]
