Vulnerabilidades do Microweber Microweber

Microweber CMS through 2.0.20 contains a stored cross-site scripting vulnerability in the content tagging system that allows admin-authenticated attackers to inject arbitrary JavaScript by submitting malicious payloads via the tag_names parameter of the GET /api/save_content_admin endpoint, bypassing three independent sanitization controls including XSS middleware that ignores GET requests, a strip_unsafe() function that only matches double-quoted onerror attributes, and a titlecase normalizer that passes HTML decimal entity-encoded payloads through unchanged. Attackers can store malicious scripts that execute without user interaction for every visitor to the public blog page and within the admin post editor, enabling session riding through same-origin fetch requests using the CSRF token embedded in the page.

Cross Site Scripting vulnerability in the "/admin/category/create" endpoint of Microweber 2.0.19. An attacker can manipulate the "rel_id" parameter in a crafted URL and lure a user with admin privileges into visiting it, achieving JavaScript code execution in the victim's browser. The issue was reported to the developers and fixed in version 2.0.20.

Cross Site Scripting vulnerability in the "/admin/order/abandoned" endpoint of Microweber 2.0.19. An attacker can manipulate the "orderDirection" parameter in a crafted URL and lure a user with admin privileges into visiting it, achieving JavaScript code execution in the victim's browser. The issue was reported to the developers and fixed in version 2.0.20.

Microweber 2.0.15 contains a stored cross-site scripting vulnerability that allows authenticated attackers to inject malicious scripts into user profile fields.
