CVE-2025-1268
Remediation/Mitigation Strategy for CVE-2025-1268
Vulnerability Description:
An out-of-bounds write vulnerability exists in the EMF Recode processing component of the Generic Plus PCL6, Generic Plus UFR II, Generic Plus LIPS4, Generic Plus LIPSLX, and Generic Plus PS Printer Drivers developed by Canon Inc. This vulnerability can be triggered when processing specially crafted EMF files.
Severity:
- CVSS Score: 9.4 (Critical)
- Vector: AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (Network, Low Attack Complexity, No Privileges Required, User Interaction Required, Unchanged Scope, High Confidentiality Impact, High Integrity Impact, High Availability Impact)
This high severity score indicates that a remote attacker can potentially execute arbitrary code on a vulnerable system. The need for user interaction, like opening a malicious document, lowers the attack surface, but the potential for a complete system compromise makes this a critical vulnerability.
Known Exploit:
While a specific exploit is not described here, the nature of an out-of-bounds write vulnerability suggests that a successful exploit could allow an attacker to:
- Execute arbitrary code with the privileges of the user running the driver.
- Gain control of the affected system.
- Cause a denial of service.
- Potentially elevate privileges.
Remediation/Mitigation Steps:
Apply Vendor Patch: The primary remediation step is to immediately install the official patch or updated driver package released by Canon Inc. This patch will address the vulnerability in the EMF Recode processing component. Check Canon’s official website for the relevant driver updates for your specific printer model and operating system.
Disable EMF Processing (If Possible): If a patch is unavailable or cannot be immediately applied, consider temporarily disabling EMF processing in the printer driver settings. This is a viable mitigation only if it does not severely impact printing functionality. Check printer and driver documentation for instructions.
User Education: Educate users about the risks of opening untrusted or unsolicited documents, especially those containing embedded graphics. Emphasize the importance of verifying the source of documents before opening them. Phishing awareness training can significantly reduce the risk of exploitation.
Endpoint Detection and Response (EDR): Ensure that endpoint detection and response (EDR) solutions are deployed and properly configured. EDR tools can help detect and prevent exploitation attempts by monitoring system behavior for malicious activity related to this vulnerability.
Input Validation: Implement or enhance input validation routines for EMF files processed by the driver. This can help detect and reject malformed or malicious files before they can trigger the vulnerability. (This is a developer-side mitigation strategy)
Regular Vulnerability Scanning: Implement a regular vulnerability scanning program to identify and address vulnerabilities in a timely manner. This includes scanning for missing patches and misconfigurations that could expose systems to attack.
Least Privilege: Ensure users operate under the principle of least privilege. Restrict user access rights to only what is necessary to perform their job duties. This can limit the impact of a successful exploit.
