Неправильная нейтрализация символов в кодировке HTML в функции проверки URL-адреса в Checkmk <2.5.0p5, <2.4.0p31, <2.3.0p48 и всех версиях 2.2.0 позволяет аутентифицированному пользователю обойти проверку URL-адреса и внедрить вредоносные URL-адреса, такие как javascript: URI, что приводит к межсайтовому сценарию, когда другой пользователь взаимодействует со созданной ссылкой.
Показать оригинальное описание (EN)
Improper neutralization of HTML-encoded characters in the URL validation function in Checkmk <2.5.0p5, <2.4.0p31, <2.3.0p48, and all 2.2.0 versions allows an authenticated user to bypass URL validation and inject malicious URLs such as javascript: URIs, resulting in cross-site scripting when another user interacts with the crafted link.
