CVE-2017-5255 describes a critical command injection vulnerability in Cambium Networks ePMP firmware versions 3.5 and prior, affecting ePMP 1000 and 2000 series devices. An authenticated user, including a low-privilege readonly account, can execute arbitrary OS commands as root by injecting shell meta-characters into specially crafted POST requests to the get_chart function on the web management console. This vulnerability carries a CVSS score of 8.8 (HIGH) due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV, multiple Metasploit modules and an ExploitDB entry confirm the availability of public exploit code, indicating a high likelihood of exploitation. Community discussion and media coverage further highlight the attention this vulnerability has received.
