CVE-2021-41162Network attack vector

Cross-site scripting via incorrect JavaScript sanitization

Published Apr 21, 2022 · Updated Apr 23, 2025

Cross-site scripting in Combodo iTop 3.0.0-beta through 3.0.0-beta5 allows remote attackers to execute script via wizard_helper. GetJsForUpdateFields passes m_sWizHelperJsVarName to utils::Sanitize with an incorrect argument position, leaving the JavaScript variable name insufficiently filtered. Exploitation requires a user to open a crafted request; the resulting script executes in that user's iTop browser context.
