CVE-2022-27230 is a reflected cross-site scripting (XSS) vulnerability affecting multiple versions of F5 BIG-IP APM and F5 BIG-IP Guided Configuration. This vulnerability allows attackers to execute JavaScript in the context of the currently logged-in user, leading to potential unauthorized actions. The severity of this vulnerability is classified as high, with a CVSS score of 7.5, indicating that it poses a significant risk to organizations leveraging these systems.
Risk to organizations includes the possibility of attackers gaining unauthorized access to sensitive information or performing actions on behalf of legitimate users. With this vulnerability, the attacker must have the ability to trick the user into interacting with a malicious link, which could be delivered through various means, such as phishing.
As of the latest updates, there are no confirmed public exploits available for this vulnerability, meaning that while it is serious, active exploitation has not been reported. Organizations should prioritize patching immediately to mitigate any risk associated with this vulnerability.
The urgency for defenders to address this issue cannot be overstated, especially given the widespread deployment of F5 products in critical infrastructure.
Vulnerability Details
On all versions of 16.1.x, 15.1.x, 14.1.x, 13.1.x, 12.1.x, and 11.6.x of F5 BIG-IP APM, as well as F5 BIG-IP Guided Configuration (GC) all versions prior to 9.0, a reflected cross-site scripting (XSS) vulnerability exists. This vulnerability is categorized under CWE-79, reflecting the issue of improper neutralization of input during web page generation.
The CVSS score of 7.5 indicates a high severity classification. The vulnerability has a network attack vector, high attack complexity, and requires user interaction. The impacts are significant, affecting confidentiality, integrity, and availability, all categorized as high.
This vulnerability was published on May 5, 2022, and remains relevant for numerous users of the affected F5 products.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user input on an undisclosed page of the F5 BIG-IP Guided Configuration interface. Attackers may exploit this weakness by crafting a malicious URL that injects JavaScript code into the application context, executed when a victim clicks on the link.
The attack vector is primarily network-based, and the complexity is high because the attacker needs to trick a user into clicking on a link. No privileges are required to initiate the attack, but user interaction is crucial. The vulnerability’s impact extends to confidentiality, integrity, and availability, all of which are assessed as high.
Risk & Impact Analysis
Organizations utilizing affected versions of F5 BIG-IP APM and Guided Configuration face significant risks. The potential for unauthorized access to sensitive data and execution of malicious scripts poses a serious threat to operational security and data integrity. High-profile installations may attract targeted attacks, amplifying the need for rapid remediation.
The exploitation of this vulnerability could lead to severe reputational damage as well as financial loss stemming from data breaches or operational disruptions. Given the CVSS score and the lack of active exploits reported, organizations should consider this vulnerability a high priority in their patch management process.
