CVE-2020-27600 is a critical command injection vulnerability affecting D-Link DIR-846 routers (A1_100.26 firmware), specifically within the HNAP1/control/SetMasterWLanSettings.php endpoint. Attackers can remotely execute arbitrary commands by injecting shell metacharacters into the ssid0 or ssid1 parameters, requiring no authentication or user interaction. With a CVSS score of 9.8 (CRITICAL), this flaw allows for complete compromise of confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) or active exploitation has been observed, and community discussion is minimal, the high EPSS score indicates a significant likelihood of future exploitation.
