CVE-2020-35753Public exploitNetwork attack vector

Browser script execution via unneutralized SENDER parameter

Published Jan 22, 2021 · Updated Aug 4, 2024

Cross-site scripting in Persis Human Resource Management Portal 17.2.00–17.2.35 and 19.0.00–19.0.20 allows remote attackers to run browser script. The enabled Recommend job posting form places the untrusted SENDER parameter into page output without neutralizing executable content. Exploitation requires the feature to be enabled and a user to interact with crafted content; the script then executes within that user's portal session.
