CVSS v3.1

Official Description

Several Ricoh printers have multiple buffer overflows parsing HTTP parameter settings for Wi-Fi, mDNS, POP3, SMTP, and notification alerts, which allow an attacker to cause a denial of service or code execution via crafted requests to the web server. Affected firmware versions depend on the printer models. One affected configuration is cpe:2.3:o:ricoh:sp_c250dn_firmware:-:*:*:*:*:*:*:* up to (including) 1.06 running on cpe:2.3:o:ricoh:sp_c250dn:-:*:*:*:*:*:*:*, cpe:2.3:o:ricoh:sp_c252dn:-:*:*:*:*:*:*:*. Another affected configuration is cpe:2.3:o:ricoh:sp_c250sf_firmware:-:*:*:*:*:*:*:* up to (including) 1.12 running on cpe:2.3:o:ricoh:sp_c250sf:-:*:*:*:*:*:*:*, cpe:2.3:o:ricoh:sp_c252sf:-:*:*:*:*:*:*:*.

Technical Analysis

CVE-2019-14305 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
