What is CVE-2019-25294?

html5_snmp version 1.11 is vulnerable to a persistent cross-site scripting (XSS) attack. This flaw allows attackers to inject malicious JavaScript through the 'Remark' parameter in the 'add_router_operation.php' file. By crafting a specific POST request containing a script payload in the Remark field, an attacker can execute arbitrary scripts in the browsers of users who load the affected page. This vulnerability poses a significant risk as it may lead to unauthorized actions performed on behalf of users or the exposure of sensitive information.
