CVE-2023-0353Public exploitNetwork attack vector

Credential disclosure via hard-coded decryption password

Published Mar 13, 2023 · Updated Jan 16, 2025

Recoverable password storage in Akuvox E11 111.30.2.19 and earlier allows remote authenticated users to decrypt passwords from a configuration file. The firmware encrypts stored passwords with a proprietary weak cipher and embeds the corresponding decryption password in the firmware. Access to an exported configuration or firmware image is required, and successful exploitation reveals reusable credentials.
