Redaxo 5.21.3 前版本 CSRF 令牌繞過漏洞 允許許可權提升
CVE-2026-117536 - REDAXO before 5.21.3 CSRF Token Bypass via users/users Privilege Escalation
Redaxo 在 5.21.3 之前的版本存在 CSRF 令牌繞過漏洞,攻擊者可透過 crafted GET 連結提升至管理者許可權或停用帳號。
- 漏洞機制:後臺使用者管理頁面僅在 save 引數時檢查 CSRF token,FUNC_UPDATE 路徑不需要,允許未驗證的請求。
此漏洞允許攻擊者在未驗證 CSRF token 的情況下提升許可權,Redaxo 使用者須即時升級至 5.21.3 以上以防止管理權被奪取或帳號被停用,並檢查後臺使用者管理功能的安全設定以確保系統完整性

REDAXO 5.21.3 之前的版本在後臺使用者管理頁面 (users/users) 存在跨站請求偽造 (CSRF) 漏洞,因為 CSRF 令牌檢查僅在設定 save 引數時才執行,而由 FUNC_UPDATE 觸發的更新路徑則不需要此檢查。攻擊者可誘使已登入後臺、擁有 users[] 許可權的使用者點選精心製作的 GET 連結,以授予管理員許可權、停用帳號或鎖定唯一管理員。

Action Type Old Value New Value Added Description REDAXO before 5.21.3 contains a cross-site request forgery vulnerability in the backend user administration page (users/users) because the CSRF token check only runs when the save parameter is set, while the update path triggered by FUNC_UPDATE does not require it. Attackers can lure a logged-in backend user with the users[] permission to a crafted GET link to grant administrator rights, deactivate accounts, or lock out the sole administrator.
