The vulnerability CVE-2015-8310 represents a cross-site scripting flaw in Cherry Music version 0.36.0 and earlier, classified under CWE-79 Improper Neutralization of Input During Web Page Generation. This vulnerability affects the web-based user interface of the music streaming application where authenticated users can manipulate the playlistname parameter during playlist creation. The flaw stems from insufficient input validation and output encoding mechanisms within the application's web framework, specifically in how user-supplied data is processed and rendered back to the browser. Attackers exploiting this vulnerability can inject malicious scripts that execute in the context of other users' browsers, potentially leading to session hijacking, data theft, or unauthorized actions within the application's interface.
The technical implementation of this vulnerability occurs when Cherry Music processes the playlistname field without proper sanitization of special characters that could be interpreted as HTML or JavaScript code. When an authenticated user creates a playlist with malicious input containing script tags or other XSS payloads in the playlist name field, the application fails to properly encode or escape this input before displaying it in subsequent web pages. This creates an environment where the injected code becomes part of the page's HTML content and executes when other users view the playlist or related interface elements. The vulnerability is particularly concerning because it requires only authenticated access, meaning that users with valid credentials can exploit this weakness without needing additional privileges.
The operational impact of CVE-2015-8310 extends beyond simple script execution, as it can enable attackers to perform various malicious activities within the application's environment. An attacker could craft payloads that steal session cookies, redirect users to malicious sites, or modify playlist contents to compromise user data integrity. The vulnerability affects the confidentiality, integrity, and availability of the application's user data, particularly when multiple users share the same system. Given that Cherry Music operates as a web-based music streaming platform, the exploitation could lead to unauthorized access to user playlists, personal music collections, and potentially sensitive user information stored within the application's database. This type of vulnerability also aligns with ATT&CK technique T1059.001 Command and Scripting Interpreter for executing malicious code within the victim's browser context.
Mitigation strategies for this vulnerability include immediate patching of Cherry Music to version 0.36.0 or later, which contains proper input validation and output encoding mechanisms. Organizations should implement comprehensive input sanitization that filters or escapes special characters in user-supplied data before processing or storing it. The application should employ proper output encoding techniques such as HTML entity encoding when displaying user-generated content in web interfaces. Additional defensive measures include implementing content security policies that restrict script execution within the application's web pages, using secure session management practices, and conducting regular security testing including dynamic application security testing to identify similar vulnerabilities. Network-level protections such as web application firewalls can provide additional layers of defense, though the primary solution remains updating the vulnerable software and implementing proper input validation practices that align with secure coding standards and OWASP Top Ten guidelines.
