Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: AEM Dispatcher fails to properly implement URL filters. π **Consequences**: Remote attackers can bypass security rules entirely. This breaks the intended access control layer.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Improper URL filtering implementation. π **Flaw**: The Dispatcher component does not validate or sanitize URL paths correctly, allowing malicious patterns to slip through.
π» **Action**: Bypass Dispatcher rules. π **Impact**: Access restricted resources (e.g., .json paths) that should return 403/404. β οΈ **Privileges**: Remote, unauthenticated access to internal content.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Low. π **Auth**: Remote attackers. No authentication required. π **Config**: Only requires the vulnerable Dispatcher version to be active.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: Yes. π **PoC**: Available on GitHub (nuclei-templates, fuckwbored). π οΈ **Method**: Use extensions like `.gif` or `.css` (e.g., `/bin/querybuilder.json.gif`) to bypass filters.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for AEM Dispatcher endpoints. π§ͺ **Test**: Request paths with added extensions (e.g., `.json.css`). β **Success**: If the server responds with content instead of 403/404, you are vulnerable.
π§ **Workaround**: If patching is delayed, implement strict WAF rules. π« **Block**: Block requests with unusual extensions on sensitive paths. π **Limit**: Restrict access to `/bin/` endpoints at the network level.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: High. π **Priority**: Critical. β‘ **Reason**: Easy exploitation, no auth needed, bypasses core security. Patch ASAP to prevent data exposure.
