Multiple reflected cross-site scripting (XSS) vulnerabilities exist in undisclosed pages of the BIG-IP Configuration utility which allow an attacker to run JavaScript in the context of the currently logged-in user. This vulnerability allows attackers to manipulate user sessions and potentially execute malicious scripts.
The CVSS score for this vulnerability is 7.5, categorized as high, indicating significant risk to organizations. Organizations should prioritize patching immediately.
Risk to organizations includes unauthorized data access and manipulation, as attackers may exploit this vulnerability to gain sensitive information from the affected systems.
Currently, there are no known exploits in the wild, but the nature of XSS vulnerabilities means that exploitation could be straightforward for attackers. Organizations should address in priority patch cycle.
Given that this vulnerability affects multiple versions of various F5 BIG-IP products, the urgency for defenders to apply patches cannot be overstated.
Organizations utilizing affected products must ensure they are updated to the latest versions to mitigate risk effectively.
Vulnerability Details
The vulnerability is classified under CWE-79, indicating a weakness related to improper neutralization of input during web page generation. The affected products include:
BIG-IP Access Policy Manager, Advanced Firewall Manager, Advanced Web Application Firewall, Analytics, Application Acceleration Manager, Application Security Manager, Application Visibility and Reporting, Carrier Grade NAT, DDoS Hybrid Defender, Domain Name System, Edge Gateway, Fraud Protection Service, Global Traffic Manager, Link Controller, Local Traffic Manager, Policy Enforcement Manager, SSL Orchestrator, Web Accelerator, and Websafe.
The CVSS vector string indicates the attack vector is network-based, with high attack complexity and requiring user interaction. The impacts on confidentiality, integrity, and availability are all rated high.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user inputs, leading to reflected XSS attacks. Attackers may craft malicious links that, when clicked by a user, execute scripts within their browser context.
The attack vector is primarily network-based, requiring the victim to interact with the malicious link. The complexity is rated high due to the need for successful user engagement.
No privileges are required to exploit this vulnerability, making it accessible for attackers. User interaction is mandatory, as the attack relies on users opening the malicious link.
The confidentiality, integrity, and availability impacts are all rated high, meaning an attacker could not only steal sensitive information but also manipulate its integrity and potentially disrupt services.
Risk & Impact Analysis
Real-world deployment risks associated with this vulnerability are significant, especially in environments where sensitive data is handled or where regulatory compliance is crucial.
Organizations that fail to address this vulnerability may face unauthorized data access, leading to potential data breaches and compliance violations. The blast radius is substantial, as multiple F5 products are affected, increasing the urgency for remediation.
The urgency assessment based on the CVSS score indicates that organizations should prioritize patching immediately.
