Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Path Traversal in Ubiquiti Web UI. π **Consequences**: Attackers upload arbitrary files β‘οΈ Gain **Root Privileges** β‘οΈ Full device compromise. π₯ Critical impact on network infrastructure.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **CWE**: Directory Traversal (Path Traversal). π **Flaw**: The Web management interface fails to sanitize user input, allowing access to restricted file system paths. π Unrestricted file writing capability.
π **Privileges**: **Root Access**. π **Data**: Upload/Write **Arbitrary Files**. π **Impact**: Complete control over the device. Can install backdoors, modify configs, or pivot to internal network. π« No user restriction.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: Likely **Low/Medium**. π **Auth**: Requires access to the Web Management Interface. πΆ **Config**: If the management port is exposed to the internet or untrusted LAN, exploitation is trivial.β¦
β **Yes**. π **Exploit-DB**: ID 39701. π **HackerOne**: Report 73480. π οΈ **Metasploit**: Module `ubiquiti_airos_file_upload` exists. π Wild exploitation is possible given public PoCs.
Q7How to self-check? (Features/Scanning)
π **Scan**: Look for Ubiquiti airOS versions. π‘ **Nmap**: Identify Ubiquiti web services. π **Check**: Verify firmware version against the list (e.g., 7.1.3, 5.6.2).β¦
β **Fixed**. π’ **Official Notice**: Ubiquiti released security updates. π **Action**: Update to **airOS 5.6.5+** or latest stable release. π See community.ubnt.com for official patch notes. π‘οΈ Patch immediately.
Q9What if no patch? (Workaround)
π§ **Workaround**: Disable remote access to the Web UI. π« **Firewall**: Block port 80/443 from untrusted networks. π **Network Segmentation**: Isolate management VLAN. π΅ If possible, restrict access to trusted IPs only.β¦
π₯ **Priority**: **CRITICAL**. π¨ **Urgency**: **HIGH**. π **Risk**: Root access via simple web upload. π’ **Action**: Patch NOW. π‘οΈ Protects against active exploits in Metasploit/Exploit-DB. β³ Do not delay.
