CVE-2019-10933 in Spectrum Power 3
Summary
by MITRE
A vulnerability has been identified in Spectrum Power 3 (Corporate User Interface) (All versions <= v3.11), Spectrum Power 4 (Corporate User Interface) (Version v4.75), Spectrum Power 5 (Corporate User Interface) (All versions <= v5.50), Spectrum Power 7 (Corporate User Interface) (All versions <= v2.20). The web server could allow Cross-Site Scripting (XSS) attacks if unsuspecting users are tricked into accessing a malicious link. User interaction is required for a successful exploitation. The user does not need to be logged into the web interface in order for the exploitation to succeed. At the stage of publishing this security advisory no public exploitation is known.

This vulnerability affects multiple versions of Spectrum Power corporate user interfaces across different product lines including Spectrum Power 3, 4, 5, and 7. The flaw manifests as a cross-site scripting vulnerability that could enable attackers to execute malicious scripts in the context of a victim's browser. The vulnerability is particularly concerning because it does not require users to be authenticated to the web interface for exploitation to occur, making it accessible to any user who visits a malicious link. This represents a significant security risk as it allows for unauthorized code execution within the victim's browser session without requiring any credentials or privileged access. The vulnerability stems from inadequate input validation and output encoding within the web application's handling of user-supplied data, which is a common weakness in web applications that process external input without proper sanitization.
The technical implementation of this XSS vulnerability occurs when the application fails to properly escape or filter user-controllable input before rendering it in web pages. This allows attackers to inject malicious scripts that execute in the victim's browser context, potentially leading to session hijacking, data theft, or further exploitation of the victim's browser environment. The vulnerability is classified as a client-side attack vector where the malicious payload is delivered through a malicious link that users are tricked into clicking. This aligns with CWE-79 which specifically addresses cross-site scripting vulnerabilities and their potential for unauthorized script execution. The attack requires user interaction but does not require authentication, making it particularly dangerous in environments where users may encounter untrusted links in emails, social media, or other communication channels.
The operational impact of this vulnerability extends beyond simple script execution as it could enable attackers to establish persistent access to user sessions, steal sensitive information, or manipulate the application's functionality. The lack of authentication requirements means that even unauthenticated users could be compromised, potentially affecting the entire user base of the affected systems. This vulnerability could be leveraged for credential theft, session manipulation, or as a stepping stone for more sophisticated attacks within the network. The affected versions span multiple generations of the Spectrum Power product line, indicating a widespread issue that affects various deployment scenarios and potentially different organizational environments. Security teams should be particularly concerned about the potential for this vulnerability to be used in targeted phishing campaigns or as part of broader attack chains where initial access is established through social engineering.
Mitigation strategies should focus on implementing proper input validation and output encoding across all user-controllable data paths within the affected applications. Organizations should deploy web application firewalls that can detect and block XSS attack patterns, implement content security policies to restrict script execution, and ensure that all user-supplied data is properly sanitized before being rendered in web pages. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other applications within the organization's attack surface. The vulnerability also highlights the importance of keeping software updated and implementing security patches promptly. Organizations should consider implementing user education programs to reduce the risk of social engineering attacks that exploit this vulnerability, as the attack requires user interaction to be successful. Additionally, monitoring for suspicious user behavior and implementing proper access controls can help detect and prevent exploitation attempts. The lack of known public exploitation at the time of advisory publication does not diminish the severity of the vulnerability, as it represents a potential vector for future attacks that could be leveraged by threat actors with sufficient motivation and resources.
