CVE-2025-14237: CWE-787: Out-of-bounds Write in Canon Inc. Satera LBP670C Series
CVE-2025-14237 is a critical buffer overflow vulnerability in the XPS font parsing component of Canon Small Office Multifunction Printers and Laser Printers, specifically affecting multiple product series with firmware version 06.02 and earlier. This vulnerability allows an attacker on the same network segment to cause the device to become unresponsive or potentially execute arbitrary code remotely without any privileges or user interaction. The affected products include various Canon printer series sold in Japan, the US, and Europe. The vulnerability has a high CVSS 4.0 score of 9.3, indicating a critical risk. No official patch or remediation information is currently provided, and no known exploits are reported in the wild. Users should monitor vendor advisories for updates and consider network segmentation or limiting access to affected devices as interim measures.
AI Analysis
Technical Summary
CVE-2025-14237 is a buffer overflow vulnerability (CWE-787) in the XPS font parsing functionality of Canon Satera LBP670C Series and related printer models. The flaw exists in firmware versions 06.02 and earlier and can be triggered by an attacker on the same network segment, potentially causing denial of service or arbitrary code execution. The vulnerability affects multiple Canon printer series across Japan, the US, and Europe. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, with high impact on confidentiality, integrity, and availability. No patch or official remediation has been disclosed yet.
Potential Impact
Successful exploitation can lead to the printer becoming unresponsive (denial of service) or allow remote code execution, which could compromise the device and potentially the network it is connected to. The vulnerability affects confidentiality, integrity, and availability of the affected devices. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, restrict network access to affected printers to trusted users and segments only. Monitor Canon's official communications for updates on fixes or temporary mitigations. Avoid exposing these devices to untrusted networks.
