Password disclosure via reversible cookie encoding
Published Feb 24, 2026 · Updated Feb 24, 2026
Cleartext credential storage in Binardat 10G08-0800GSM firmware before V300SP10260209 allows attackers to recover a user password. The web interface writes the password into a client-side cookie after Base64 encoding it, a reversible transformation that provides no confidentiality. Exploitation requires access to the cookie value; the established consequence is password disclosure, with no reported direct integrity or availability impact.
