Script execution via unneutralized administrative form fields

Published Jan 30, 2020 · Updated Aug 6, 2024

Cross-site scripting in HitMyServer HMS Testimonials before 2.0.11 allows remote attackers to inject script through administrative forms. The testimonial, default-settings, custom-field, and template handlers accept seven named parameters and place executable markup into plugin pages without neutralization. A remote attacker must induce an authenticated administrator to submit a crafted form; successful execution can deface the public site or the plugin's admin area.
