Q4What can hackers do? (Privileges/Data)
π **Attacker Power**: Full control! Can execute arbitrary code, steal database credentials, modify site content, and pivot to other network assets. **High Impact** (CVSS H).
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. CVSS indicates **No Privileges (PR:N)**, **No User Interaction (UI:N)**, and **Network Access (AV:N)**. Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit Status**: No public PoC listed in data. However, the flaw is clear (missing validation). Wild exploitation is **likely** due to low barrier to entry.
Q7How to self-check? (Features/Scanning)
