Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Default SSH private key exposure in **Ceragon FibeAir IP-10**. π **Consequences**: Remote attackers gain unauthorized SSH access. Critical security breach due to hardcoded credentials.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: The `authorized_keys` file contains a **default SSH public key** for the `mateidu` user. β **Flaw**: Hardcoded credentials instead of unique, generated keys per device.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **Ceragon FibeAir IP-10** (Wireless Backhaul Node). π **Vendor**: Ceragon. β οΈ **Scope**: Devices using this specific hardware model with default configurations.
Q4What can hackers do? (Privileges/Data)
π» **Privileges**: Full **SSH access** as user `mateidu`. π **Data**: Potential remote code execution, network configuration changes, and data exfiltration.β¦
π **Threshold**: **LOW**. π **Auth**: No authentication required (public key is known). βοΈ **Config**: Default settings exploited. Remote exploitation is trivial for any attacker with network access.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: **YES**. π **References**: PacketStorm Security, Full Disclosure mailing list, GitHub Gist. π **Status**: Well-documented PoC available since April 2015.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Ceragon FibeAir IP-10** devices. ποΈ **Test**: Attempt SSH login with the known default private key for `mateidu`.β¦
π οΈ **Fix**: Official patches or key rotation updates from **Ceragon**. π **Mitigation**: Change default keys immediately. π **Published**: Advisory released June 2017 (initial disclosure April 2015).
Q9What if no patch? (Workaround)
π§ **No Patch?**: 1οΈβ£ **Isolate** device from public networks. 2οΈβ£ **Change** the `mateidu` user's SSH keys immediately. 3οΈβ£ **Restrict** SSH access via ACLs. π **Critical**: Do not leave default keys active.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. π¨ **Priority**: Immediate action required. π **Risk**: Automated exploitation is likely due to known default keys. π‘οΈ **Action**: Patch or rotate keys NOW to prevent remote takeover.
