Vulnerability Analysis<\/strong><\/h2>\n

CVE-2020-24602 is a Reflected cross-site scripting vulnerability in Openfire Product (Openfire version 4.5.1). A cross-site scripting (XSS) attack can cause arbitrary code (javascript) to run in a user\u2019s browser while the browser is connected to a trusted web site. The application becomes an attack vehicle by targeting the users. XSS payload executes whenever the user views the crafted POST request with XSS Payload in Openfire 4.5.0 Product.<\/p>\n

Proof of Concept<\/strong><\/h2>\n

Product<\/strong>: Openfire Product<\/p>\n

Vendor<\/strong>: Ignite Realtime<\/p>\n

Product version<\/strong>: Openfire version 4.5.1<\/p>\n

Privilege<\/strong>: admin<\/p>\n

Request type<\/strong>: GET<\/p>\n

Vulnerable URL<\/strong>: http:\/\/localhost:9090\/server-properties.jsp<\/a>,<\/p>\n

http:\/\/localhost:9090\/security-audit-viewer.jsp<\/a><\/p>\n

Vulnerable Parameter<\/strong>: \u201csearchName\u201d,\u201d searchValue\u201d, \u201csearchDescription\u201d, \u201csearchDefaultValue\u201d, \u201csearchPlugin\u201d, \u201csearchDescription\u201d and \u201csearchDynamic\u201d a<\/p>\n

Steps to Reproduce<\/strong>:<\/h2>\n

Issue 01<\/strong>: Reflected Cross-Site Scripting<\/strong><\/p>\n

Step 1<\/strong>: Log in to the application (admin) through this URL in Firefox.<\/p>\n

Step 2<\/strong>: Navigate to this URL and press ALT+SHIFT+X to execute the malicious javascript in the browser.<\/p>\n

Similarly, add XSS payload ‘+accesskey=’X’+onclick=’alert(document.cookie) to the other vulnerable variables \u201csearchName\u201d,\u201d searchValue\u201d, \u201csearchDescription\u201d, searchDefaultValue\u201d, \u201csearchPlugin\u201d,\u201csearchDescription\u201d and \u201csearchDynamic\u201d in formid \u2018paginationForm\u2019 which reflects in the browser.<\/p>\n
