On F5 BIG-IP versions 16.1.x prior to 16.1.2.2, 15.1.x prior to 15.1.5.1, and 14.1.x prior to 14.1.4.6, a stored cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility (also referred to as the BIG-IP TMUI). This vulnerability allows an attacker to execute JavaScript in the context of the currently logged-in user.
The severity level of this vulnerability is classified as high, with a CVSS score of 8. This indicates that the potential impact on affected systems is significant, making it imperative for organizations to take immediate action.
Risk to organizations includes the potential for unauthorized actions performed by attackers, which can lead to data breaches, loss of sensitive information, and damage to organizational reputation. The exploitation of this vulnerability could result in severe consequences, particularly for organizations that rely on F5 BIG-IP for their network infrastructure.
Organizations should prioritize patching immediately to mitigate this risk. Ensuring that all installations of F5 BIG-IP are updated to the latest versions is crucial in defending against potential exploitation.
As of now, there are no known public exploits for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog.
Organizations using affected versions must schedule remediation as part of their priority patch cycle to ensure they are protected against this vulnerability.
Vulnerability Details
The vulnerability was published on May 5, 2022, by F5. It is classified under CWE-79, which pertains to improper neutralization of input during web page generation ('cross-site scripting').
The CVSS score provided by F5 is 8.0, indicating a high severity level. The attack vector is network-based, requiring low attack complexity and low privileges to exploit. User interaction is required, as the attacker must trick a user into executing the malicious script.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly sanitize user input, allowing for the injection of malicious scripts into web pages displayed to users. The attack vector being network-based means that an attacker can exploit this vulnerability from a remote location.
The attack complexity is low, requiring minimal effort to exploit. Privileges required are also low, as the attacker does not need special permissions to execute the attack. User interaction is necessary, as the attacker must convince the user to visit a crafted URL or click on a malicious link.
The impact of this vulnerability is significant: it can compromise confidentiality, integrity, and availability of the affected systems, allowing attackers to hijack user sessions, steal sensitive data, or disrupt services.
Risk & Impact Analysis
The potential risk to organizations is substantial, given the prevalence of F5 BIG-IP in enterprise environments. The blast radius could extend to all users with access to the affected configurations, making it crucial for security teams to assess their deployment and determine the urgency of patching.
Given the CVSS score of 8.0, organizations should take this vulnerability seriously and prioritize it within their remediation efforts. The ability for attackers to execute JavaScript in the context of logged-in users poses a significant threat, especially if sensitive information or critical operations are involved.
The urgency for addressing this vulnerability is high, and organizations should incorporate it into their priority patch cycle to prevent exploitation.
