Java vulnerability analysis and mitigation
Overview
A Cross Site Scripting (XSS) vulnerability was discovered in Nacos version 2.0.3. The vulnerability exists in the auth/users endpoint and can be triggered through the pageSize and pageNo parameters (NVD, GitHub Issue).
Technical details
The vulnerability affects the auth/users endpoint in Nacos 2.0.3 and can be exploited through two parameters: pageSize and pageNo. The XSS payload can be injected through either parameter without requiring any authentication or special conditions (GitHub Issue).
Impact
If successfully exploited, this Cross Site Scripting vulnerability could allow attackers to execute arbitrary JavaScript code in the context of the user's browser session, potentially leading to theft of sensitive information or session hijacking (NVD).
Exploitability
The vulnerability is easily exploitable as it requires no authentication and can be triggered through simple URL manipulation. Example payloads include: '/nacos/v1/auth/users?pageNo=1&pageSize=alert(1)' and '/nacos/v1/auth/users?pageNo=alert(1)&pageSize=1' (GitHub Issue).
