CVE-2020-10509Network attack vector

Browser-side script execution via undisclosed input handling

Published Mar 27, 2020 · Updated Sep 16, 2024

Cross-site scripting in Sunnet eHRD CTMS 8 and 9 allows remote attackers to execute script in a user's browser. TWCERT/CC does not identify the affected page, parameter, or input-handling operation that places attacker-controlled content into a response. A victim must interact with the attack mechanism; successful exploitation permits attacker-controlled browser actions within the affected site's origin.
