๐ **Privileges**: Root/System level access. ๐ **Data**: Complete control over the device. Hackers can read sensitive configs, install backdoors, or use the router as a pivot point for network attacks.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: LOW. ๐ **Auth**: None required (PR:N). ๐ก **Access**: Network vector (AV:N). ๐ซ **UI**: No user interaction needed (UI:N). This is a critical, remote, unauthenticated exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: Yes. ๐ **Evidence**: GitHub PoC available (Litengzheng/vuldb_new). ๐ **Tags**: Exploit code is publicly accessible, making exploitation easy for threat actors.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for the specific firmware version `7.4cu.2313_b20191024`. ๐ก **Network**: Look for exposure of the `/cgi-bin/cstecgi.cgi` endpoint.โฆ
