Sensitive-data disclosure via hardcoded JSON encryption key
Published Mar 3, 2026 · Updated Mar 3, 2026
Hardcoded-key cryptography in Weintek cMT-3072XH2 easyweb 2.1.53 on OS 20231011 allows remote attackers to read sensitive system data. Sensitive JSON responses are encrypted with a fixed embedded key in ECB mode, allowing captured ciphertext to be decrypted outside the HMI. Network access to Easyweb traffic is sufficient; the published assessment reports confidentiality loss without data modification or service interruption.
