漏洞描述信息
在Fluent Bit 3.1.9中发现了一个问题。当Prometheus Remote Write输入插件正在运行并监听一个IP地址和端口时,可以通过发送一个Content-Length: 0的包来使服务器崩溃。当Content-Length为0时,处理不当允许用户(具有访问端点权限)执行远程拒绝服务攻击。崩溃的原因是当将0(来自Content-Length)传递给函数cfl_sds_len时发生了一个空指针解引用,该函数尝试将一个空指针转换为struct cfl_sds。这与prom_rw_prot.c中的process_payload_metrics_ng()相关。

漏洞描述信息
An issue was discovered in Fluent Bit 3.1.9. When the Prometheus Remote Write input plugin is running and listening on an IP address and port, one can send a packet with Content-Length: 0 and it crashes the server. Improper handling of the case when Content-Length is 0 allows a user (with access to the endpoint) to perform a remote Denial of service attack. The crash happens because of a NULL pointer dereference when 0 (from the Content-Length) is passed to the function cfl_sds_len, which in turn tries to cast a NULL pointer into struct cfl_sds. This is related to process_payload_metrics_ng() at prom_rw_prot.c.
