📡🚨 NEW TENDA CH22 COMMAND-INJECTION FLAW DISCLOSED — PUBLIC EXPLOIT ALREADY AVAILABLE CyberSignal Daily ✓ · Network Security · August 23, 2026 🎯 A new remote command-injection vulnerability has been published for the Tenda CH22 networking device. 🔥 CVE-2026-78063 📊 CVSS 3.1: 7.4 / High 🔴 Affected: Tenda CH22 firmware 1.0.0.1 🌐 Remote attack ⚠️ Public exploit available The vulnerability affects the device's: /goform/editFileName management functionality. Improper handling of the `editNameMit` parameter allows attacker-controlled input to reach operating-system command processing. Conceptually: 🌐 malicious request ↓ 📡 Tenda management interface ↓ ❌ input improperly handled ↓ 💻 OS command injection ↓ ☠️ attacker-controlled commands execute on the device. The risk is more urgent because: 🔥 exploit information has already been publicly released. That does NOT mean attacks are currently confirmed. At this check: ❌ no verified active exploitation campaign ❌ no evidence of mass compromise has been reported. But public exploit availability reduces the distance between: vulnerability disclosure → real-world scanning. 🛡️ Defenders should restrict device-management interfaces to trusted networks, avoid direct internet exposure, monitor unusual management requests and watch closely for vendor remediation. 🧠 Why it matters: routers and edge devices provide attackers a valuable position where endpoint EDR may have little or no visibility. 🔗 Sources: CVE Program • NVD • VulDB • Tenda #CyberSecurity #Tenda #CVE202678063 #CommandInjection #RouterSecurity #NetworkSecurity #CyberNews
