The vulnerability identified as CVE-2015-9247 affects the Skybox Platform version prior to 7.5.401 and represents a critical reflected cross-site scripting flaw that exposes users to potential security risks. This vulnerability manifests within the platform's web service endpoints, specifically targeting the /skyboxview/webservice/services/VersionRepositoryWebService interface where the soapenv:Body element becomes a vector for malicious script injection. The flaw also extends to the login.html page through the status parameter, creating multiple attack surfaces for adversaries seeking to exploit this weakness.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding within the Skybox Platform's web service architecture. When user-supplied data flows through the soapenv:Body element or the status parameter without proper sanitization, malicious scripts can be injected and subsequently executed in the context of other users' browsers. This reflects a classic reflected XSS vulnerability pattern where attacker-controlled input is immediately reflected back to the user without adequate security controls. The vulnerability aligns with CWE-79 which defines Cross-Site Scripting as a condition where an application includes untrusted data in a new web page without proper validation or escaping, allowing attackers to execute scripts in the victim's browser.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform various malicious activities including session hijacking, credential theft, and redirection to malicious sites. An attacker could craft specially formatted requests that, when executed by a victim's browser, would steal session cookies or inject malicious code that persists across user sessions. The reflected nature of this vulnerability means that the attack requires user interaction, typically through phishing emails or social engineering tactics that direct victims to malicious URLs. This vulnerability directly maps to several ATT&CK techniques including T1566 for spearphishing and T1059 for command and scripting interpreter, as it enables attackers to execute malicious code within victim environments.
Mitigation strategies for CVE-2015-9247 should prioritize immediate patching of the Skybox Platform to version 7.5.401 or later, which contains the necessary security fixes. Organizations should implement comprehensive input validation mechanisms that sanitize all user-supplied data before processing, particularly focusing on the soapenv:Body element and status parameter handling. Output encoding should be enforced across all web service endpoints to prevent malicious scripts from executing in browser contexts. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and filtering traffic to these vulnerable endpoints. Regular security assessments should verify that all web service interfaces properly validate and sanitize input data, ensuring that the platform maintains robust defenses against similar reflected XSS vulnerabilities. The remediation process should also include user education about phishing threats and the importance of verifying URLs before interacting with potentially compromised web services.
