The vulnerability identified as CVE-2006-1541 represents a critical SQL injection flaw within the EzASPSite content management system version 2.0 RC3 and earlier. This vulnerability specifically affects the Default.asp component which processes user input through the Scheme parameter without proper sanitization or validation. The flaw enables remote attackers to inject malicious SQL code directly into the application's database queries, potentially allowing full database access and administrative control over the affected system.
The technical implementation of this vulnerability stems from insufficient input validation and improper parameter handling within the Default.asp script. When the Scheme parameter is submitted by an attacker, the application fails to properly escape or filter special characters that could alter the intended SQL query structure. This lack of input sanitization creates an exploitable path where malicious SQL commands can be appended to legitimate database queries, effectively bypassing authentication mechanisms and allowing unauthorized access to sensitive data.
From an operational perspective, this vulnerability poses severe risks to organizations using EzASPSite 2.0 RC3 or earlier versions. Attackers can leverage this weakness to execute arbitrary SQL commands against the backend database, potentially extracting sensitive information including user credentials, personal data, and system configurations. The disclosure of SHA1 hashes of admin passwords represents a particularly dangerous aspect of this vulnerability as it provides attackers with cryptographic material that can be subjected to rainbow table attacks or brute force attempts to recover administrative credentials. This compromise can lead to complete system takeover and persistent unauthorized access.
The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws in software applications, and demonstrates characteristics consistent with ATT&CK technique T1190 for exploit public-facing applications. Organizations should implement immediate mitigations including input validation, parameterized queries, and proper output encoding to prevent SQL injection attacks. The recommended remediation involves upgrading to a patched version of EzASPSite or implementing proper input sanitization measures that prevent malicious SQL code from being executed within database queries. Additionally, network segmentation and database access controls should be enforced to limit the potential impact of such vulnerabilities. Organizations should also consider implementing web application firewalls and regular security assessments to identify and remediate similar vulnerabilities in their application portfolios.
