CVE-2024-12647
CVE-2024-12647 is a buffer overflow vulnerability in Canon printers. This flaw resides in the CPCA font download processing of several Small Office Multifunction and Laser Printers. An attacker on the same network segment could exploit this vulnerability to cause the printer to become unresponsive or, more severely, execute arbitrary code.
The affected printers include models from the Satera, Color imageCLASS, and i-SENSYS lines, with firmware versions v05.04 and earlier. While the CVSS score is 0, the SOCRadar Vulnerability Risk Score (SVRS) of 36 indicates a moderate level of risk. Successful exploitation of this buffer overflow can lead to significant disruptions and potential arbitrary code execution. Organizations using these printers should apply the necessary firmware updates to mitigate this risk and prevent unauthorized access or control of their printing devices. This Canon printer vulnerability poses a tangible threat, highlighting the importance of proactive patching.
Description
CVE-2024-12647 is a critical vulnerability affecting specific models of Canon Small Office Multifunction Printers and Laser Printers. This vulnerability stems from a buffer overflow flaw within the CPCA font download processing component. Exploitation of this flaw could allow a remote attacker on the same network segment to trigger the affected device to become unresponsive or execute arbitrary code.
Despite having a high CVSS score (9.8), the SOCRadar Vulnerability Risk Score (SVRS) for this CVE is 42. This lower SVRS indicates that although the vulnerability is severe, the immediate risk is moderate. However, it's crucial to understand that this risk can escalate quickly, especially if active exploits are discovered.
Key Insights
- Targeted Devices: This vulnerability affects specific models of Canon printers sold in Japan, US, and Europe, including the Satera MF656Cdw/MF654Cdw, Color imageCLASS MF656Cdw/MF654Cdw/MF653Cdw/MF652Cdw/LBP633Cdw/LBP632Cdw, and i-SENSYS MF657Cdw/MF655Cdw/MF651Cdw/LBP633Cdw/LBP631Cdw series. Firmware versions 05.04 and earlier are vulnerable.
- Remote Code Execution: Successful exploitation could lead to remote code execution on the affected printer, allowing an attacker to take complete control of the device. This could be used for malicious purposes like installing malware, accessing sensitive data, or launching further attacks against other devices on the network.
- Network-based Exploitation: The vulnerability can be exploited by attackers within the same network segment, meaning any device on the same network as the vulnerable printer could potentially be compromised.
- Limited Public Information: At this time, there is no publicly available information regarding specific Threat Actors/APT groups exploiting CVE-2024-12647. However, the possibility of active exploitation cannot be ruled out, particularly considering the vulnerability's severity.
Mitigation Strategies
- Update Firmware: The most effective mitigation strategy is to immediately update the firmware of all affected printers to the latest version. Canon has released patches addressing this vulnerability.
- Network Segmentation: Implement network segmentation to isolate vulnerable printers from other sensitive systems, reducing the potential impact of a successful attack.
- Restrict Network Access: Limit network access to the printers, allowing only necessary connections. This reduces the attack surface and makes it harder for attackers to exploit the vulnerability.
- Monitor for Suspicious Activity: Implement security monitoring solutions that can detect unusual activity on the network and devices, including printer behavior. This can help identify and respond to potential attacks early on.
