AVideo: Missing CSRF Protection on State-Changing JSON Endpoints Enables Forced Comment Creation, Vote Manipulation, and Category Asset Deletion

WWBN AVideo is an open source video platform. In versions 29.0 and prior, multiple AVideo JSON endpoints under `objects/` accept state-changing requests via `$_REQUEST`/`$_GET` and persist changes tied to the caller's session user, without any anti-CSRF token, origin check, or referer check. A malicious page visited by a logged-in victim can silently cast/flip the victim's like/dislike on any comment (`objects/comments_like.json.php`), post a comment authored by the victim on any video, with attacker-chosen text (`objects/commentAddNew.json.php`), and/or delete assets from any category (`objects/categoryDeleteAssets.json.php`) when the victim has category management rights. Each endpoint is reachable from a browser via a simple `<img src="…">` tag or form submission, so exploitation only requires the victim to load an attacker-controlled HTML resource. Commit 7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c contains a fix.

跨站请求伪造(CSRF)

WWBN AVideo 跨站请求伪造漏洞

WWBN AVideo是WWBN团队的一个由PHP编写的视频平台建站系统。 WWBN AVideo 29.0及之前版本存在跨站请求伪造漏洞，该漏洞源于objects/下的多个AVideo JSON端点通过$_REQUEST/$_GET接受状态更改请求并持久化更改，但未使用任何反CSRF令牌、来源检查或引用检查，可能导致登录受害者访问恶意页面时，静默更改其对任何评论的点赞/点踩状态、以受害者身份发布攻击者选定文本的评论，或在受害者拥有类别管理权限时删除任何类别中的资产。
