Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Remote Code Execution (RCE) in TerraMaster TOS. π **Consequences**: Attackers gain **root** access via a specific endpoint `/tos/index.php?app/del`. π₯ Total system compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Improper input validation in the `/tos/index.php?app/del` endpoint. β οΈ Allows injection of special inputs to trigger arbitrary command execution. π Classic injection flaw.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: TerraMaster (China). π₯οΈ **Product**: TOS (NAS OS). π¦ **Affected Models**: F4-210, F2-210. π **Version**: TOS 4.2.X (specifically 4.2.15-2107141517).
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Executes commands as **root**. ποΈ **Data**: Full control over NAS storage. π΅οΈ **Action**: Arbitrary code execution. π Complete takeover of the server.
Q5Is exploitation threshold high? (Auth/Config)
π **Auth**: Likely requires authentication to access the TOS web interface. π‘ **Config**: Network exposure of the NAS management port increases risk. π Threshold: Medium (needs access to the specific PHP endpoint).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: Yes. π **References**: PacketStorm Security & ThatsN0tMy.site posts. π§ͺ **PoC**: Available online. π **Wild Exploitation**: Potential for automated attacks if endpoint is exposed.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for `/tos/index.php?app/del` endpoint. π **Tools**: Use vulnerability scanners targeting TerraMaster TOS. π **Visual**: Look for TOS 4.2.x versions in network inventory.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Patch**: Official fix status not explicitly detailed in data. β οΈ **Action**: Check TerraMaster support site for updates. π **Mitigation**: Apply vendor patches immediately if available.
Q9What if no patch? (Workaround)
π§ **Workaround**: Block external access to the management interface. π« **Firewall**: Restrict `/tos/index.php` access to trusted IPs only. π **Disable**: If possible, disable unnecessary web services.
Q10Is it urgent? (Priority Suggestion)
π₯ **Priority**: **CRITICAL**. π¨ **Urgency**: High. π£ **Reason**: Root-level RCE with public PoCs. π **Action**: Patch or isolate immediately. β³ Time is of the essence.
