CVE-2020-14935 describes a critical buffer overflow vulnerability in Contiki-NG versions 4.4 through 4.5, specifically within the SNMP bulk get request response encoding function. This flaw allows an attacker to overwrite stack regions, including the return address, by sending a crafted SNMP bulk get request. With a CVSS score of 9.8 (Critical), this vulnerability has a network attack vector, low attack complexity, and high impacts on confidentiality, integrity, and availability, potentially leading to remote code execution. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), it is not listed in the KEV catalog, and there is minimal community discussion or media coverage, suggesting it is not actively exploited in the wild.
