Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical trust management flaw in Schneider Electric EVlink Charging Stations.β¦
π‘οΈ **Root Cause**: **CWE-798** (Use of Hard-coded Credentials). π **Flaw**: The device likely relies on static, hardcoded credentials for authentication, allowing anyone with the default password to gain access.
π» **Attacker Actions**: Issue **unauthorized commands** to the web server. π **Privileges**: Gain **administrative privileges**. π **Data**: Potential full control over the charging station's configuration and operation.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Low**. Since it involves hard-coded credentials, exploitation likely requires only network access to the device's web interface and knowledge of the default password.β¦
π₯ **Public Exp?**: **Yes**. A Proof of Concept (PoC) exists in the **Nuclei templates** repository (projectdiscovery/nuclei-templates). This makes automated scanning and exploitation significantly easier.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Use vulnerability scanners like **Nuclei** with the specific CVE-2021-22707 template.β¦
π§ **No Patch Workaround**: If updating is impossible, **isolate** the device on a separate VLAN. π« **Block Access**: Restrict web interface access via firewall rules to trusted IPs only.β¦
β‘ **Urgency**: **HIGH**. With public PoCs available and the severity of gaining admin control over physical infrastructure, immediate patching to **V3.4.0.1+** is strongly recommended.
