Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A critical auth bypass in RWS WorldServer. ๐ **Consequences**: Attackers can upload and execute arbitrary Java code via `.jar` files. Total system compromise is possible.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Authentication logic flaw. Specifically, adding `token=02` bypasses all security checks. ๐ซ No proper validation of this parameter allows unauthorized access.
Q3Who is affected? (Versions/Components)
๐ข **Affected**: RWS WorldServer versions **before 11.7.3**. ๐ฆ Enterprise translation management systems are the primary target.
Q4What can hackers do? (Privileges/Data)
๐ป **Attacker Power**: Full arbitrary Java code execution. ๐ Can upload malicious `.jar` archives to the `ws-api/v2/customizations/api` endpoint. Complete control over the server.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: LOW. ๐๏ธ No valid credentials needed. Just send a request with `token=02`. The vulnerability explicitly bypasses *all* authentication requirements.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp?**: YES. ๐ Proof of Concept (PoC) is available via Nuclei templates on GitHub. Wild exploitation is highly likely given the ease of use.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for the `ws-api/v2/customizations/api` endpoint. ๐งช Test if sending `token=02` grants access without standard login credentials. Use automated scanners like Nuclei.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: YES. ๐ Upgrade to **RWS WorldServer 11.7.3** or later. The vendor has released a patch to address this specific bypass mechanism.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Block external access to `ws-api/v2/customizations/api`. ๐ซ Implement strict WAF rules to reject requests containing `token=02` in that specific path. Isolate the server.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: CRITICAL. ๐จ High severity due to RCE potential and zero-auth requirement. Immediate patching or mitigation is required to prevent total system takeover.
