CVE-2007-4077 in Video Share Enterprise
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in AlstraSoft Video Share Enterprise allow remote attackers to inject arbitrary web script or HTML via the (1) msg, (2) page, (3) viewkey, or (4) viewtype parameter to (a) view_video.php; the (5) next parameter to (b) signup.php; the (6) search_id parameter to (c) search_result.php; the (7) category or (8) page parameter to (d) video.php; the (9) receiver parameter to (e) compose.php; the (10) catgy parameter to (f) groups.php; the (11) channelname parameter to (g) siteadmin/channels.php; or the (12) uname parameter to (h) siteadmin/muser.php.

The CVE-2007-4077 vulnerability represents a critical cross-site scripting flaw in AlstraSoft Video Share Enterprise version 2.0 and earlier, affecting multiple web application endpoints through insufficient input validation and output encoding mechanisms. This vulnerability falls under the CWE-79 weakness category, which specifically addresses cross-site scripting vulnerabilities where untrusted data is improperly sanitized before being rendered in web pages. The flaw exists across twelve distinct parameters within various PHP scripts, creating a widespread attack surface that could potentially compromise user sessions and enable unauthorized access to sensitive application functionality.
The technical implementation of this vulnerability stems from the application's failure to properly sanitize user-supplied input across multiple HTTP parameters. Attackers can exploit these flaws by injecting malicious JavaScript code or HTML content through parameters such as msg, page, viewkey, viewtype, next, search_id, category, page, receiver, catgy, channelname, and uname. The vulnerability is particularly concerning because it affects both user-facing pages like view_video.php, signup.php, and search_result.php, as well as administrative interfaces including siteadmin/channels.php and siteadmin/muser.php. When these parameters are processed without proper sanitization, the injected content gets executed in the context of other users' browsers, creating persistent XSS attack vectors.
The operational impact of this vulnerability extends beyond simple script injection, as it enables attackers to perform session hijacking, steal user credentials, manipulate application data, and potentially gain administrative privileges. The attack surface covers both frontend user interactions and backend administrative functions, making it particularly dangerous for organizations relying on this video sharing platform. According to ATT&CK framework category T1190, this vulnerability represents a server-side web application attack vector that can be leveraged for privilege escalation and data exfiltration. The persistence of these vulnerabilities across multiple endpoints suggests a systemic lack of input validation controls within the application architecture, potentially indicating broader security weaknesses in the codebase.
Mitigation strategies should focus on implementing comprehensive input validation and output encoding mechanisms across all user-supplied parameters. The primary defense involves sanitizing all input data through proper HTML escaping techniques before rendering content in web pages, which aligns with OWASP Top 10 recommendations for preventing XSS attacks. Organizations should implement Content Security Policy (CSP) headers to limit script execution contexts, employ proper parameter validation using allowlists of acceptable values, and ensure consistent output encoding across all application components. Additionally, regular security code reviews and automated vulnerability scanning should be implemented to identify similar weaknesses in other application components. The vulnerability highlights the importance of defense-in-depth strategies and proper secure coding practices, particularly for applications handling user-generated content and administrative interfaces where the potential for privilege escalation exists.
