A recent security vulnerability identified as CVE-2024-47295 poses a serious risk for several SEIKO EPSON devices, potentially granting attackers administrative control. This vulnerability stems from a weak initial password setup within SEIKO EPSON’s Web Config software, which manages network device settings for products like printers and scanners.
Web Config, a tool for configuring SEIKO EPSON devices via web browsers, lacks an administrative password on affected models when first connected to a network without prior configuration. This absence of a password allows any network user to establish a new password, gaining full access to the device.
The vulnerability report notes, “If the administrator password on the affected device is left blank, anyone accessing it through Web Config can set a new password.” An attacker with administrative rights could manipulate device settings, interrupt operations, or use the device to infiltrate broader network systems.
Currently, there is no available patch to fix this vulnerability. SEIKO EPSON urges users to set an administrative password immediately upon installation and network connection. The company’s Security Guidebook stresses this step in section 3, advising users to configure Web Config settings and secure the device with a strong password to block unauthorized access and mitigate the risk of this exploit.
SEIKO EPSON also advises caution with all networked devices. Unsecured IoT devices are frequently targeted by cybercriminals, and the CVE-2024-47295 vulnerability has received a CVSS score of 8.1, highlighting its high-risk level. Best practices to reduce risk include:
- Using Strong, Unique Passwords: Set complex passwords during initial setup and avoid defaults.
- Restricting Network Access: Limit access to trusted users and networks only.
- Monitoring Device and Network Activity: Regularly review configurations and monitor network traffic for unusual activity.
With these steps, users can enhance device security and safeguard against potential threats.
