Vulnerability Details
The official description states that VMware Aria Operations contains a stored cross-site scripting vulnerability. The CVSS score from the NVD is 9, indicating critical severity, while VMware provides a slightly lower score of 8. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation ('cross-site scripting').
The affected products include VMware Aria Operations, Cloud Foundation, Telco Cloud Infrastructure, and Telco Cloud Platform, specifically versions before the vendor patch.
Technical Analysis
The root cause of this vulnerability is the lack of proper input validation, allowing for the execution of arbitrary scripts. The attack vector is network-based, and the complexity of the attack is low. Attackers require low privileges and user interaction is necessary to execute the attack. The impact on confidentiality, integrity, and availability is high.
Risk & Impact Analysis
Real-world deployment risk is significant, as this vulnerability could allow attackers to gain unauthorized access and manipulate sensitive data. Organizations using affected VMware products are at high risk of data breaches and operational disruption due to the ease of exploitation. The urgency for remediation is high, given the critical nature of the vulnerability and the potential for significant damage.
