CVE-2005-0413 in MyPHP Forum
Summary
by MITRE
Multiple SQL injection vulnerabilities in MyPHP Forum 1.0 allow remote attackers to execute arbitrary SQL commands via (1) the fid in forum.php, (2) the member parameter in member.php, (3) the email parameter in forgot.php, or (4) the nbuser or nbpass parameters in include.php. NOTE: it was later reported that vector 2 exists in 3.0 and earlier.

The vulnerability described in CVE-2005-0413 represents a critical security flaw in MyPHP Forum version 1.0 and later versions, specifically targeting SQL injection attack vectors that enable remote code execution. This vulnerability resides in multiple files within the forum application, creating multiple entry points for malicious actors to exploit the underlying database communication mechanisms. The affected parameters include fid in forum.php, member in member.php, email in forgot.php, and nbuser or nbpass in include.php, all of which fail to properly sanitize user input before incorporating it into SQL queries. The vulnerability classification aligns with CWE-89, which specifically addresses SQL injection flaws where untrusted data is directly included in SQL command strings without proper validation or escaping mechanisms. These attack vectors demonstrate a fundamental lack of input validation and output encoding practices that are essential for preventing database manipulation attacks.
The operational impact of this vulnerability is severe as it allows remote attackers to execute arbitrary SQL commands against the underlying database system. Attackers can leverage these injection points to retrieve sensitive information, modify database contents, delete records, or even gain administrative access to the forum's database. The attack surface expands significantly when considering that the vulnerability affects multiple files within the application, increasing the probability of successful exploitation. The fact that vector 2 was later reported to exist in version 3.0 and earlier versions indicates that this is not an isolated issue but rather a persistent design flaw that spans multiple releases of the software. This persistence suggests inadequate security testing and code review processes during the software development lifecycle, potentially leaving other components vulnerable to similar attacks. The vulnerability directly maps to attack techniques described in the MITRE ATT&CK framework under the T1190 category for exploit public-facing application, specifically targeting the use of SQL injection as a method for database access and manipulation.
The technical implementation of this vulnerability stems from improper handling of user-supplied data within SQL query construction. When parameters such as fid, member, email, nbuser, or nbpass are directly concatenated into SQL statements without proper parameterization or input sanitization, attackers can inject malicious SQL code that alters the intended query behavior. This flaw typically occurs when developers assume that input validation alone is sufficient, failing to implement proper prepared statements or parameterized queries that separate SQL command structure from data values. The vulnerability's persistence across multiple versions indicates that the core architectural flaw was not addressed through code refactoring or security patching, leaving users exposed to continuous risk. Security best practices dictate that all user inputs should be treated as untrusted and properly escaped or parameterized before database interaction, which was clearly not implemented in the MyPHP Forum application. The exploitation of these vulnerabilities can result in complete database compromise, data exfiltration, and potential system-wide impact depending on the database permissions and access controls in place. Organizations using affected versions should immediately implement mitigations including input validation, parameterized queries, and database access restrictions to prevent unauthorized SQL command execution and protect against the associated security risks.
