CVE-2007-3783 in enVivo!CMS
Summary
by MITRE
SQL injection vulnerability in default.asp in enVivo!CMS allows remote attackers to execute arbitrary SQL commands via the ID parameter in an article action. NOTE: this is probably different from CVE-2005-1413.4.

The vulnerability identified as CVE-2007-3783 represents a critical sql injection flaw within the enVivo!CMS content management system, specifically affecting the default.asp script. This vulnerability manifests when the application processes user input through the ID parameter in article action requests, creating an exploitable condition that allows remote attackers to inject malicious sql commands directly into the database layer. The flaw resides in the application's insufficient input validation and sanitization mechanisms, which fail to properly escape or filter user-supplied data before incorporating it into sql queries. Such vulnerabilities typically fall under the common weakness enumeration category CWE-89, which specifically addresses sql injection weaknesses in software applications. The attack vector is particularly concerning as it enables remote code execution without requiring authentication or privileged access, making it highly attractive to threat actors seeking to compromise web applications.
The operational impact of this vulnerability extends far beyond simple data theft, as successful exploitation can result in complete database compromise, data exfiltration, and potential lateral movement within affected networks. Attackers can leverage this vulnerability to manipulate database contents, extract sensitive information, modify or delete critical data, and potentially establish persistent backdoors within the compromised system. The vulnerability's classification as a remote attack vector means that threat actors can exploit it from anywhere on the internet without requiring physical access to the target infrastructure. This characteristic aligns with attack techniques documented in the attack pattern taxonomy under techniques that involve database manipulation and command execution through web interfaces. The severity is compounded by the fact that the vulnerability affects a core content management system component, potentially compromising all content managed through the affected platform.
Mitigation strategies for CVE-2007-3783 require immediate implementation of input validation and parameterized query approaches to prevent sql injection attacks. Organizations should implement proper input sanitization by validating all user-supplied data against strict whitelists and implementing proper escape sequences for special sql characters. The recommended defensive measures include upgrading to patched versions of enVivo!CMS, implementing web application firewalls to detect and block malicious sql injection attempts, and conducting thorough code reviews to identify similar vulnerabilities in other application components. Additionally, database access controls should be strictly enforced through principle of least privilege, ensuring that application database accounts have minimal required permissions. Security monitoring should be enhanced to detect unusual database access patterns and potential exploitation attempts, while regular vulnerability assessments should be conducted to identify and remediate similar sql injection vulnerabilities across the entire application stack. The remediation process should also include comprehensive staff training on secure coding practices and the importance of input validation in preventing sql injection attacks.
