CVE-2024-1490: CWE-94 Improper Control of Generation of Code ('Code Injection') in WAGO CC100 (0751-9x01)
CVE-2024-1490 is a high-severity vulnerability in the WAGO CC100 (0751-9x01) PLC that allows an authenticated remote attacker with high privileges to execute arbitrary shell commands via the OpenVPN configuration accessible through the device's web-based management interface. This occurs if user-defined scripts are permitted, enabling code injection through improper control of code generation. The vulnerability has a CVSS score of 7. 2, indicating significant impact on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability (CWE-94) affects the WAGO CC100 (0751-9x01) programmable logic controller. An attacker with valid high-privilege credentials can exploit the OpenVPN configuration interface exposed via the web management portal to inject and execute arbitrary shell commands. The issue arises when user-defined scripts are allowed in OpenVPN, leading to improper control over code generation and enabling code injection. The vulnerability is network exploitable with low attack complexity and does not require user interaction. The impact includes full compromise of the device's confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated attacker with high privileges to execute arbitrary commands on the affected PLC, potentially leading to complete device compromise. This can affect the confidentiality, integrity, and availability of the system controlled by the PLC. No known exploits are reported in the wild, but the vulnerability poses a significant risk if leveraged.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the web-based management interface to trusted administrators only and disable user-defined scripts in the OpenVPN configuration if possible. Monitor vendor communications for updates on patches or official mitigations.
