CVE-2007-1548 in Web Wiz Forums
Summary
by MITRE
SQL injection vulnerability in functions/functions_filters.asp in Web Wiz Forums before 8.05a (MySQL version) does not properly filter certain characters in SQL commands, which allows remote attackers to execute arbitrary SQL commands via \" (backslash double-quote quote) sequences, which are collapsed into \ , as demonstrated via the name parameter to forum/pop_up_member_search.asp.

The vulnerability described in CVE-2007-1548 represents a critical SQL injection flaw within the Web Wiz Forums software ecosystem, specifically targeting the MySQL version of the application. This vulnerability exists in the functions_filters.asp file where the application fails to properly sanitize user input before incorporating it into SQL database queries. The flaw manifests when certain character sequences are processed, particularly the backslash double-quote combination that gets collapsed into a single backslash character during processing. This particular weakness allows malicious actors to manipulate the application's database interactions through carefully crafted input parameters.
The technical exploitation of this vulnerability occurs through the manipulation of the name parameter within the forum/pop_up_member_search.asp script. When a user submits data containing the specific backslash double-quote sequence, the application's input filtering mechanism fails to adequately escape or sanitize these characters before they are incorporated into SQL command construction. This failure creates a pathway for attackers to inject malicious SQL code that executes within the database context, potentially allowing full control over the underlying database system. The vulnerability operates at the application layer, specifically targeting the data validation and input sanitization mechanisms that should prevent such malicious input from being processed as executable commands.
The operational impact of this vulnerability extends beyond simple data theft or modification. Attackers who successfully exploit this SQL injection flaw can potentially gain unauthorized access to sensitive user information, including member details, forum data, and potentially system credentials. The vulnerability allows for arbitrary SQL command execution, which means attackers can perform read, write, and delete operations on the database, potentially leading to complete system compromise. This type of vulnerability is particularly dangerous because it can be exploited remotely without requiring authentication, making it an attractive target for automated attacks and widespread exploitation across multiple installations.
Organizations utilizing Web Wiz Forums versions prior to 8.05a face significant risk from this vulnerability, as it represents a fundamental flaw in the application's security architecture. The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications, and demonstrates the critical importance of proper input validation and output encoding practices. From an ATT&CK framework perspective, this vulnerability maps to techniques involving command injection and credential access, as attackers can leverage the SQL injection to escalate privileges and extract sensitive information from the database. The recommended mitigation strategy involves immediate patching to version 8.05a or later, which includes proper input sanitization and escape sequence handling. Additionally, implementing proper parameterized queries, input validation, and output encoding mechanisms would provide defense-in-depth against similar vulnerabilities in the future.
