The CVE-2007-2991 vulnerability represents a critical cross-site scripting flaw within the Evenzia Content Management System that exposes web applications to malicious script injection attacks. This vulnerability specifically targets the includes/send.inc.php component of the CMS, making it a significant concern for organizations relying on this platform for their web content management needs. The flaw exists within the application's handling of PATH_INFO parameters, which are typically used by web servers to pass additional information to scripts through the URL path. When an attacker crafts a malicious URL containing crafted script code within the PATH_INFO portion, the vulnerable Evenzia CMS fails to properly sanitize or validate this input before rendering it in the web response, creating an exploitable condition for XSS attacks.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding practices within the Evenzia CMS codebase. The send.inc.php file does not properly escape or filter user-supplied data from the PATH_INFO variable before incorporating it into dynamic web content. This failure to implement proper security controls for user input processing creates a direct pathway for attackers to inject malicious scripts that execute within the context of other users' browsers. The vulnerability is classified as a persistent XSS attack vector since the malicious code can be stored and executed whenever legitimate users access the affected pages. This type of vulnerability is particularly dangerous because it can be leveraged to steal session cookies, perform unauthorized actions on behalf of users, or redirect victims to malicious websites. The weakness aligns with CWE-79, which specifically addresses Cross-site Scripting vulnerabilities where insufficient validation of input data leads to injection of malicious code into web applications.
The operational impact of CVE-2007-2991 extends beyond simple script injection, creating substantial risks for organizations running Evenzia CMS installations. Attackers can exploit this vulnerability to execute arbitrary code in victims' browsers, potentially compromising user accounts through session hijacking or credential theft. The vulnerability can be exploited through various attack vectors including phishing campaigns, where users are directed to malicious URLs containing crafted PATH_INFO parameters. Additionally, the attack can be automated through web crawlers or social engineering tactics that encourage users to click on compromised links. Organizations may experience data breaches, unauthorized access to sensitive information, and potential regulatory compliance violations depending on the nature of data processed through the vulnerable CMS. The long-term consequences include damage to organizational reputation, legal liability, and the need for costly remediation efforts.
Mitigation strategies for CVE-2007-2991 should prioritize immediate patching of the Evenzia CMS installation to address the root cause of the vulnerability. Organizations should implement comprehensive input validation and output encoding mechanisms throughout their web applications to prevent similar issues from occurring in the future. The implementation of Content Security Policy headers can provide additional defense-in-depth measures to limit the execution of unauthorized scripts even if the primary vulnerability is exploited. Regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities across the entire application infrastructure. Network monitoring solutions should be configured to detect and alert on suspicious URL patterns that may indicate exploitation attempts. Organizations should also consider implementing web application firewalls to filter malicious traffic before it reaches vulnerable application components. The vulnerability demonstrates the importance of following secure coding practices as outlined in OWASP Top 10 and NIST guidelines, particularly focusing on input validation and output encoding controls. According to ATT&CK framework, this vulnerability maps to T1059.007 for script execution and T1566 for social engineering techniques that may be employed in exploitation campaigns.
