CVE-2022-26020Public exploitNetwork attack vector

Privileged credential disclosure via hard-coded AES key

Published May 12, 2022 · Updated Apr 15, 2025

Information disclosure in InHand Networks InRouter302 V3.5.4 allows remote authenticated users to recover privileged credentials. The aes_encrypt_str function encrypts sensitive NVRAM entries with a hard-coded AES key, while the authenticated configuration-export endpoint returns those ciphertexts. Any logged-in low-privileged user can download config.dat, decrypt administrator credentials and private keys, and use the recovered secrets for increased access.
