The vulnerability described in CVE-2005-1946 represents a critical security flaw in Invision Blog software versions prior to 1.1.2 Final, specifically targeting SQL injection weaknesses that enable remote attackers to execute arbitrary SQL commands. This vulnerability exists within the application's handling of user-supplied input parameters, creating a pathway for malicious actors to manipulate database queries and potentially gain unauthorized access to sensitive information or system resources.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the application's core components. Attackers can exploit this weakness by manipulating the eid parameter during editentry, replyentry, or editcomment actions, as well as the mid parameter in aboutme actions. These parameters are directly incorporated into SQL queries without proper escaping or parameterization, allowing attackers to inject malicious SQL code that gets executed by the database server. The vulnerability falls under CWE-89 which specifically addresses SQL injection flaws where untrusted data is used to construct SQL queries without proper validation or sanitization.
The operational impact of this vulnerability is significant as it provides attackers with the capability to perform unauthorized database operations including data extraction, modification, or deletion. An attacker could potentially access user credentials, personal information, or other sensitive data stored within the blog's database. The remote execution capability means that attackers do not require physical access to the system, making this vulnerability particularly dangerous as it can be exploited from anywhere on the internet. This type of vulnerability aligns with ATT&CK technique T1190 which describes exploiting vulnerabilities in remote services to gain unauthorized access.
The exploitation of this vulnerability requires minimal technical expertise and can be accomplished through automated tools or manual techniques. Attackers typically craft malicious input strings that contain SQL injection payloads, such as single quotes or semicolon characters, which are then processed by the vulnerable application. The lack of proper input validation in the affected parameters creates a persistent security risk that affects all users of the vulnerable software version, potentially compromising the entire blog installation and its associated data.
Organizations using affected versions of Invision Blog should immediately implement mitigations including updating to version 1.1.2 Final or later, implementing proper input validation and parameterization of all database queries, and applying web application firewalls to detect and block malicious SQL injection attempts. Additionally, regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other applications. The vulnerability demonstrates the critical importance of input validation and proper database query construction practices, which are fundamental security controls that should be implemented across all web applications to prevent similar exploitation scenarios.
