CVE-2018-3953 is an OS command injection vulnerability affecting Linksys E1200 (Firmware Version 2.0.09) and E2500 (Firmware Version 3.0.04) routers. It arises from improper filtering of data passed to and retrieved from NVRAM, specifically when the 'Router Name' input is processed. This vulnerability carries a high CVSS score of 7.2, indicating a network-based attack with low complexity, requiring high privileges, and leading to complete compromise of confidentiality, integrity, and availability. While not listed on CISA's KEV catalog, public exploit modules exist for Metasploit, and its EPSS score suggests a higher-than-average probability of exploitation. Despite the availability of exploit code, there is no evidence of active exploitation, and it has received minimal community discussion or media coverage.
