CVSS v3.1 |
| NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Versions prior to 0.24.5 have a Heap-Use-After-Free (UAF) vulnerability within the MQTT bridge client component (implemented via the underlying NanoNNG library). The vulnerability is triggered when NanoMQ acts as a bridge connecting to a remote MQTT broker. A malicious remote broker can trigger a crash (Denial of Service) or potential memory corruption by accepting the connection and immediately sending a malformed packet sequence. Version 0.34.5 contains a patch. The patch enforces stricter protocol adherence in the MQTT client SDK embedded in NanoMQ. Specifically, it ensures that CONNACK is always the first packet processed in the line. This prevents the state confusion that led to the Heap-Use-After-Free (UAF) when a malicious server sent a malformed packet sequence immediately after connection establishment. As a workaround, validate the remote broker before bridging. |
| NanoMQ is a messaging broker/bus for IoT Edge & SDV. Versions prior to 0.24.4 have a buffer overflow case while the PUBLISH packets trigger both shared subscription and vanila subscription. This is fixed in version 0.24.4. As a workaround, disable shared subscription. |
| An issue in nanomq v0.22.7 allows attackers to cause a Denial of Service (DoS) via a crafted request. The number of data packets received in the recv-q queue of the Nanomq process continues to increase, causing the nanomq broker to fall into a deadlock and be unable to provide normal services. |
| NanoMQ 0.17.5 has a one-byte heap-based buffer over-read in the conn_handler function of mqtt_parser.c when it processes malformed messages. |
| An access control issue in NanoMQ v0.21.10 allows attackers to bypass security restrictions and access sensitive system topic messages using MQTT wildcard characters. |
| NanoMQ v0.17.9 was discovered to contain a heap use-after-free vulnerability via the component sub_Ctx_handle. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted SUBSCRIBE message. |
| NanoMQ 0.17.5 was discovered to contain a segmentation fault via the component /nanomq/pub_handler.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted PUBLISH message. |
| NanoMQ v0.22.10 was discovered to contain a heap overflow which allows attackers to cause a Denial of Service (DoS) via a crafted CONNECT message. |
| A segmentation fault in NanoMQ v0.21.10 allows attackers to cause a Denial of Service (DoS) via crafted messages. |
| NanoMQ v0.22.10 was discovered to contain a memory leak which allows attackers to cause a Denial of Service (DoS) via a crafted PUBLISH message. |
| Buffer Overflow vulnerability in the get_var_integer function in mqtt_parser.c in NanoMQ 0.21.7 allows remote attackers to cause a denial of service via a series of specially crafted hexstreams. |
| Null Pointer Dereference vulnerability in topic_filtern function in mqtt_parser.c in NanoMQ 0.21.7 allows attackers to cause a denial of service. |
| A heap-buffer-overflow vulnerability in the read_byte function in NanoMQ v.0.21.7 allows attackers to cause a denial of service via transmission of crafted hexstreams. |
| nanomq 0.21.2 contains a Use-After-Free vulnerability in /nanomq/nng/src/core/socket.c. |
| In NanoMQ v0.15.0-0, segment fault with Null Pointer Dereference occurs in the process of decoding subinfo_decode and unsubinfo_decode. |
| In NanoMQ v0.15.0-0, a Heap overflow occurs in copyn_utf8_str function of mqtt_parser.c |
| In NanoMQ v0.15.0-0, Heap overflow occurs in read_byte function of mqtt_code.c. |
| A memory leak vulnerability exists in NanoMQ 0.17.2. The vulnerability is located in the file message.c. An attacker could exploit this vulnerability to cause a denial of service attack by causing the program to consume all available memory resources. |
| A heap buffer overflow vulnerability exists in NanoMQ 0.17.2. The vulnerability can be triggered by calling the function nmq_subinfo_decode() in the file mqtt_parser.c. An attacker could exploit this vulnerability to cause a denial of service attack. |
| A heap buffer overflow vulnerability exists in NanoMQ 0.17.2. The vulnerability can be triggered by calling the function copyn_str() in the file mqtt_parser.c. An attacker could exploit this vulnerability to cause a denial of service attack. |
