Last modified

CVE-2021-41555 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. In ARCHIBUS Web Central 21.3.3.815 (a version from 2014), XSS occurs in /archibus/dwr/call/plaincall/workflow.runWorkflowRule.dwr because the data received as input from clients is re-included within the HTTP response returned by the application without adequate validation. In this way, if HTML code or client-side executable code (e.g., Javascript) is entered as input, the expected execution flow could be altered. EPSS estimates a 0.74% chance of exploitation in the next 30 days.
