CVE-2020-6985 describes a critical vulnerability in Moxa PT-7528 (firmware v4.0 or lower) and PT-7828 (firmware v3.9 or lower) series devices, where a hard-coded service code grants unauthorized console access. With a CVSS score of 9.8 (CRITICAL), this vulnerability allows an unauthenticated attacker to achieve full compromise (confidentiality, integrity, availability) over the network with low attack complexity. While the EPSS score is low, indicating a low probability of exploitation in the wild, there is currently no public exploit code available (Metasploit, Nuclei, ExploitDB) and no community discussion or media coverage has been observed.
