The vulnerability CVE-2016-3080 represents a cross-site scripting flaw within the spacewalk-java component of Red Hat Satellite 5.7, specifically affecting the monitoring probe display functionality. This issue falls under the CWE-79 category of Cross-Site Scripting, where improper input validation allows malicious actors to inject arbitrary web scripts or HTML content into web applications. The vulnerability manifests through two primary attack vectors involving the RHNMD User and Filesystem parameters, which are utilized in the display of monitoring probes within the satellite management system.
The technical exploitation of this vulnerability occurs when the application fails to properly sanitize user-supplied input parameters before rendering them in web pages. Attackers can leverage this weakness by crafting malicious payloads in either the RHNMD User or Filesystem parameters, which are then displayed without adequate output encoding or filtering. This allows attackers to execute malicious scripts in the context of other users' browsers, potentially leading to session hijacking, data theft, or unauthorized actions within the targeted environment. The vulnerability specifically impacts the monitoring probe display functionality, which is a critical component for system administrators to oversee and manage their infrastructure.
The operational impact of CVE-2016-3080 extends beyond simple script injection, as it compromises the integrity of the Red Hat Satellite management platform. System administrators who rely on the monitoring probes for operational oversight could unknowingly be exposed to malicious code execution, potentially allowing attackers to gain unauthorized access to sensitive system information or manipulate monitoring data. The vulnerability affects the core functionality of Red Hat Satellite 5.7, which serves as a comprehensive systems management solution for enterprise environments, making it particularly dangerous in production settings where multiple administrators interact with the platform.
Organizations should implement immediate mitigations including input validation and output encoding mechanisms to prevent XSS attacks, specifically targeting the RHNMD User and Filesystem parameters within the monitoring probe display functionality. The recommended approach involves implementing proper parameter sanitization and HTML escaping techniques before displaying any user-supplied data in web interfaces. Additionally, organizations should consider implementing Content Security Policy headers and regular security assessments of their satellite management systems to identify and remediate similar vulnerabilities. This vulnerability aligns with ATT&CK technique T1059.007 for Command and Scripting Interpreter and T1566.001 for Phishing, as it enables attackers to execute malicious code through web-based attack vectors that can compromise the entire management infrastructure.
