Canon Printer Vulnerability Allows Remote Code Execution Risks

Canon Printer Flaw Enables Remote Code Execution

A critical vulnerability in Canon printer drivers has been discovered, enabling attackers to execute arbitrary code remotely. Canon issued an advisory detailing a high-severity vulnerability in its Generic Plus printer drivers affecting various printer models. The flaw, tracked as CVE-2025-1268, is an out-of-bounds vulnerability in Enhanced Metafile Recode processing, potentially allowing remote code execution.

The vulnerability arises from improper memory handling during image data conversion, leading to memory corruption and potentially granting attackers unauthorized control over affected systems. Exploitation of this flaw could result in system crashes, data leaks, or complete device compromise, particularly in networked environments. Microsoft’s Offensive Research and Security Engineering Team reported the vulnerability, which has a CVSS severity rating of 9.4.

Mahmoud Rabie, a principal solutions consultant, highlighted the impact on network security, business continuity, and compliance. Compromised printers could serve as entry points for broader network attacks, posing significant security risks. Exploitation of the vulnerability could lead to data leakage, operational disruptions, and lateral movement within corporate networks.

Canon has promised updated printer drivers addressing the vulnerability on the websites of local sales representatives. Security experts recommend isolating printers from home or office networks by connecting them directly to desktop PCs or laptops via USB to reduce the attack surface. However, this may not be practical in workplaces requiring multiple team members to connect to the same printing device.

In conclusion, the Canon printer flaw underscores the importance of promptly addressing vulnerabilities in critical devices to mitigate security risks and protect organizations from potential cyber threats. It serves as a reminder of the ongoing challenges in maintaining the security of networked devices and the need for proactive measures to safeguard against remote code execution exploits.
