π **Root Cause**: The software uses a **hardcoded/shared SSH private key** for PubkeyAuthentication. β **Flaw**: It fails to restrict access to this critical key properly.β¦
π **Affected Devices**: Eaton Power Xpert Meter **4000, 6000, and 8000**. π **Vulnerable Versions**: Firmware version **13.4.0.10 and earlier**. β **Safe**: Versions > 13.4.0.10 are patched.
Q4What can hackers do? (Privileges/Data)
π **Attacker Action**: Remote attackers can bypass authentication. ποΈ **Privilege**: They can log in via **SSH** using the shared key.β¦
β οΈ **Threshold**: **LOW**. π **Auth**: Requires **Remote** access. π **Config**: Exploits the weak PubkeyAuthentication setup. No complex setup needed if the device is exposed to the network.
Q6Is there a public Exp? (PoC/Wild Exploitation)
