  "details" : [ "Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the Netty Redis codec encoder (RedisEncoder) writes user-controlled string content directly to the network output buffer without validating or sanitizing CRLF (\\r\\n) characters. Since the Redis Serialization Protocol (RESP) uses CRLF as the command/response delimiter, an attacker who can control the content of a Redis message can inject arbitrary Redis commands or forge fake responses. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.", "A flaw was found in Netty, an asynchronous, event-driven network application framework. The Netty Redis codec encoder (RedisEncoder) does not properly validate or sanitize user-controlled string content for CRLF (Carriage Return Line Feed) characters. A remote attacker, by controlling the content of a Redis message, can inject arbitrary Redis commands or forge fake responses. This can lead to a high impact on data integrity." ],
