Published: 03 February 2026
Summary
CVE-2020-37068 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Konicaminolta Ftp Utility. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 43.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2020-37068 is a buffer overflow vulnerability (CWE-120) affecting Konica Minolta FTP Utility version 1.0, specifically in the handling of the LIST command. The flaw enables attackers to overwrite system registers by sending an oversized buffer, such as 1500 'A' characters, which disrupts normal operation of the FTP server component.
Remote attackers can exploit this vulnerability over the network with low attack complexity, requiring no privileges, user interaction, or special conditions, as reflected in its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Exploitation typically crashes the FTP server, resulting in a denial of service, and may allow potential execution of unauthorized code through register manipulation.
References include a Vulncheck advisory detailing the denial-of-service impact via the LIST command, an Exploit-DB entry (ID 48501) with a proof-of-concept exploit, the Konica Minolta US website, and a software download page for the utility. No patches or specific mitigations are described in the provided reference details.
