| CVE-2020-14936 | 1 Contiki-ng | 1 Contiki-ng | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP agent. Functions parsing the OIDs in SNMP requests lack sufficient allocated target-buffer capacity verification when writing parsed OID values. The function snmp_oid_decode_oid() may overwrite memory areas beyond the provided target buffer, when called from snmp_message_decode() upon an SNMP request reception. Because the content of the write operations is externally provided in the SNMP requests, it enables a remote overwrite of an IoT device's memory regions beyond the allocated buffer. This overflow may allow remote overwrite of stack and statically allocated variables memory regions by sending a crafted SNMP request. | |||||
| CVE-2020-14935 | 1 Contiki-ng | 1 Contiki-ng | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP bulk get request response encoding function. The function parsing the received SNMP request does not verify the input message's requested variables against the capacity of the internal SNMP engine buffer. When a bulk get request response is assembled, a stack buffer dedicated for OIDs (with a limited capacity) is allocated in snmp_engine_get_bulk(). When snmp_engine_get_bulk() is populating the stack buffer, an overflow condition may occur due to lack of input length validation. This makes it possible to overwrite stack regions beyond the allocated buffer, including the return address from the function. As a result, the code execution path may be redirected to an address provided in the SNMP bulk get payload. If the target architecture uses common addressing space for program and data memory, it may also be possible to supply code in the SNMP request payload, and redirect the execution path to the remotely injected code, by modifying the function's return address. | |||||
| CVE-2018-16663 | 1 Contiki-ng | 1 Contiki-ng. | 2023-12-10 | 4.6 MEDIUM | 7.8 HIGH |
| An issue was discovered in Contiki-NG through 4.1. There is a stack-based buffer overflow in parse_relations in os/storage/antelope/aql-parser.c while parsing AQL (storage of relations). | |||||
| CVE-2018-19417 | 1 Contiki-ng | 1 Contiki-ng | 2023-12-10 | 10.0 HIGH | 10.0 CRITICAL |
| An issue was discovered in the MQTT server in Contiki-NG before 4.2. The function parse_publish_vhdr() that parses MQTT PUBLISH messages with a variable length header uses memcpy to input data into a fixed size buffer. The allocated buffer can fit only MQTT_MAX_TOPIC_LENGTH (default 64) bytes, and a length check is missing. This could lead to Remote Code Execution via a stack-smashing attack (overwriting the function return address). Contiki-NG does not separate the MQTT server from other servers and the OS modules, so access to all memory regions is possible. | |||||

| An issue was discovered in Contiki-NG through 4.1. There is a stack-based buffer overflow in next_string in os/storage/antelope/aql-lexer.c while parsing AQL (parsing next string). | |||||
| CVE-2018-1000804 | 1 Contiki-ng | 1 Contiki-ng | 2023-12-10 | 10.0 HIGH | 9.8 CRITICAL |
| contiki-ng version 4 contains a Buffer Overflow vulnerability in AQL (Antelope Query Language) database engine that can result in Attacker can perform Remote Code Execution on device using Contiki-NG operating system. This attack appear to be exploitable via Attacker must be able to run malicious AQL code (e.g. via SQL-like Injection attack). | |||||
