## 🔬 Technical Analysis

### Vulnerability Class

The issue has been categorized as a:

```c
char buffer[256];
strcpy(buffer, attacker_input);
```

When input exceeds the allocated buffer size, adjacent memory may be overwritten.

Possible consequences include:

- Application crashes
- Stack corruption
- Control-flow hijacking
- Arbitrary code execution

## 🧪 Proof of Concept

> 🚫 No public PoC has been released at the time of writing.

When a PoC becomes available, testing should be performed only in authorized laboratory environments.

---

## 🛡 Mitigation

### Immediate Actions

- Update firmware once patches become available
- Restrict administrative access
- Disable remote management if unnecessary
- Monitor router logs
- Isolate vulnerable devices from untrusted networks
