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:-:*:*:*:*:*:*:*.
