CVE-2002-1499 in Weblog
Summary
by MITRE
Multiple SQL injection vulnerabilities in FactoSystem CMS allows remote attackers to perform unauthorized database actions via (1) the authornumber parameter in author.asp, (2) the discussblurbid parameter in discuss.asp, (3) the name parameter in holdcomment.asp, and (4) the email parameter in holdcomment.asp.

The CVE-2002-1499 vulnerability represents a critical security flaw in the FactoSystem Content Management System that exposes multiple SQL injection attack vectors. This vulnerability affects version 1.0 of the CMS and demonstrates a fundamental weakness in input validation and query construction within the application's database interaction layers. The flaw allows remote attackers to manipulate database operations through four distinct parameters across different ASP files, creating multiple entry points for malicious SQL command injection attacks.
The technical implementation of this vulnerability stems from improper sanitization of user-supplied input within the FactoSystem CMS. When the application processes the authornumber parameter in author.asp, discussblurbid parameter in discuss.asp, name parameter in holdcomment.asp, and email parameter in holdcomment.asp, it directly incorporates these values into SQL queries without adequate escaping or parameterization. This design flaw enables attackers to inject malicious SQL code that gets executed by the database server, potentially allowing full database access, data manipulation, or even system compromise. The vulnerability aligns with CWE-89 which specifically addresses SQL injection weaknesses in software applications.
The operational impact of this vulnerability extends far beyond simple data theft, as it provides attackers with the capability to perform unauthorized database actions that can compromise the entire system. Remote attackers can leverage these injection points to extract sensitive information from the database, modify or delete records, create new user accounts with elevated privileges, or even execute system commands if the database server has appropriate permissions. The multi-vector nature of the vulnerability increases the attack surface significantly, as each of the four parameters offers a separate pathway for exploitation, making it easier for attackers to succeed in their attempts.
Security professionals should consider this vulnerability in the context of the MITRE ATT&CK framework, particularly under the techniques related to SQL injection and command execution. The attack vector typically involves crafting malicious payloads that bypass input validation mechanisms, with each vulnerable parameter requiring specific payload construction. Organizations should implement comprehensive input validation, parameterized queries, and proper database access controls to mitigate these risks. The vulnerability also highlights the importance of regular security assessments and code reviews to identify and remediate such flaws before they can be exploited by malicious actors. Additionally, implementing web application firewalls and database activity monitoring systems can provide additional layers of protection against these types of attacks.
