The HTTPAuthorized function in bitcoinrpc.cpp in bitcoind 0.8.1 provides information about authentication failure upon detecting the first incorrect byte of a password, which makes it easier for remote attackers to determine passwords via a timing side-channel attack.

Security readout for executives and security teams

This CVE describes a password timing leak in bitcoind 0.8.1 RPC authentication. An attacker who can reach the RPC interface may get clues about the password one byte at a time from authentication failure timing. The source bundle does not show active exploitation or a CVSS score. Exposure is most relevant where legacy bitcoind 0.8.1 RPC services are still running and reachable by untrusted networks. Systems with RPC bound only to trusted local interfaces have lower practical exposure. Treat this as a legacy exposure issue. It is not KEV-listed, but internet-reachable RPC on old Bitcoin software can put wallet operations and funds at risk if credentials are recovered. Mitigation focus: Identify and retire any remaining bitcoind 0.8.1 deployments.; Review Bitcoin Core guidance and PR #2845 before selecting an upgrade target.; Restrict RPC access to trusted hosts while remediation is confirmed..
