  "details": "# Summary\n\nA denial of service vulnerability was discovered in ntpd-rs where an attacker can induce a message storm between two NTP servers running ntpd-rs.\n\n# Details\n\nSince ntpd-rs version 1.2.0, when configured as a server, incorrectly responded to all NTP messages sent to the server\u0027s port with a time reply, including to responses from other servers. As a consequence, a message with a spoofed IP address of another server could cause two servers running ntpd-rs to continually respond to each other, consuming significant amounts of resources.\n\n# Impact\n\nAny time server running ntpd-rs with version between 1.2.0 and 1.6.1 inclusive which allows non-NTS traffic is affected. Client-only configurations are not affected. Affected users are recommended to upgrade to version 1.6.2 as soon as possible.\n\n# Workarounds\n\nShould upgrading not be possible, the impact of the issue can be mitigated by:\n - Whitelisting access to only IP addresses of clients using the server, using the ignore filter method.\n - Blocking incoming non-request traffic on the NTP server port using a firewall.\n - Disabling public access to the vulnerable NTP server\n - Disabling the server functionality by removing any [server] sections from the configuration.\n\n# Acknowledgements\n\nThe ntpd-rs authors thank Eric Sesterhenn from X41 D-Sec GmbH for finding and reporting this issue.",

  "details": "### Impact\nThe relay\u0027s reconnect handler forwards every `RECONNECT_REQUEST` to the host without deduplication or a size cap on the `pendingReconnects` map, unlike the connect flow which guards against this with `maxPendingConnections`. An unauthenticated attacker who knows a valid session ID can send `RECONNECT_REQUEST` packets from many spoofed source addresses; each packet that passes the session lookup is forwarded to the host as a new reconnect attempt. Because the per-source rate limiter assigns a fresh token bucket to each spoofed IP, it provides no protection. The host receives one forwarded packet per spoofed source per cleanup cycle, making the relay an amplification vector for denial-of-service against the host. The host\u0027s real address is never exposed to clients by design, so this is the primary viable DoS path against it. A secondary issue: once more than `maxRateLimiters` spoofed IPs are seen, `performCleanup` calls `rateLimiters.clear()`, resetting rate limit state for all sources including legitimate ones.\n\nAffected: `NeonRelay` in all three implementations (Java, Python, TypeScript).\n\n### Patches\nNot yet patched. Fix consists of three changes to handleReconnectRequest in each implementation:\n\n1. Reject the request if `pendingReconnects.size() \u003e= maxPendingConnections` (mirrors the existing connect-flow guard)\n2. Only forward to the host if the `sessionId:clientId` key is not already present in `pendingReconnects` \u2014 the map entry can still be updated with the new source address, but the host only needs to validate once per slot\n3. In `performCleanup`, evict throttled entries before falling back to `rateLimiters.clear()` to avoid resetting legitimate sources\u0027 rate limit state\n\n### Workarounds\nOperators can partially mitigate by placing the relay behind a network-level filter that drops packets with spoofed source addresses (BCP38/uRPF). This does not address the missing `pendingReconnects` size cap or the `rateLimiters.clear()` issue but eliminates the amplification path in most deployment environments.\n\n### References\n- PROTOCOL.md \u2014 reconnect flow\n- ARCHITECTURE.md \u2014 reconnect handshake detail (step 4 describes the unbounded `put`)",
