Overview
A critical security vulnerability, identified as CVE-2025-64310, has been discovered in EPSON WebConfig and Epson Web Control, components used in SEIKO EPSON Projector Products. This flaw allows attackers to conduct brute-force attacks against administrative user passwords due to the lack of restrictions on excessive authentication attempts. This poses a significant risk to the confidentiality, integrity, and availability of affected Epson projectors.
Technical Details
The vulnerability stems from the fact that EPSON WebConfig and Epson Web Control do not implement sufficient measures to prevent or limit the number of authentication attempts. An attacker can repeatedly attempt to log in to the administrative interface using different password combinations. With enough attempts, the attacker can successfully guess the administrator’s password and gain unauthorized access to the projector’s configuration and functionality.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-64310 is 9.8 (Critical). This high score reflects the severity of the vulnerability and the potential impact of a successful exploit. A CVSS score of 9.8 indicates that the vulnerability is easily exploitable, requires low skill from the attacker, and has a high impact on the affected system. A successful exploit can lead to complete system compromise.
Possible Impact
Successful exploitation of CVE-2025-64310 could have severe consequences:
- Unauthorized Access: Attackers can gain full administrative control over the projector.
- Malicious Configuration Changes: Attackers can modify projector settings, display unwanted content, or disable the projector entirely.
- Compromised Network: A compromised projector could be used as a foothold to gain access to other devices on the network.
- Data Breach: Depending on the projector’s network configuration, attackers may be able to access sensitive data stored on or transmitted through the network.
- Denial of Service: Attackers could render the projector unusable, disrupting presentations or other critical functions.
Mitigation and Patch Steps
Epson has released a security advisory and potentially a patch to address this vulnerability. It is strongly recommended that users of affected SEIKO EPSON Projector Products take the following steps:
- Apply the Patch: Visit the Epson Support Website and download and install the latest firmware update for your projector model.
- Implement Strong Passwords: Ensure that all administrative accounts have strong, unique passwords.
- Enable Multi-Factor Authentication (MFA): If available, enable MFA for administrative accounts to provide an extra layer of security. While not explicitly stated as available, check your projector settings.
- Network Segmentation: Isolate the projector on a separate network segment to limit the potential impact of a compromise.
- Monitor Network Traffic: Monitor network traffic for suspicious activity, such as multiple failed login attempts.
