CVE-2021-21543

Dell EMC iDRAC9 versions prior to 4.40.00.00 contain multiple stored cross-site scripting vulnerabilities. A remote authenticated malicious user with high privileges could potentially exploit these vulnerabilities to store malicious HTML or JavaScript code through multiple affected parameters. When victim users access the submitted data through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable application.
