CVE-2023-23572 is a cross-site scripting vulnerability affecting SEIKO EPSON printers and their network interface Web Config. This vulnerability allows a remote authenticated attacker with administrative privileges to inject arbitrary scripts. The Web Config software, also known as Remote Manager in some products, is pre-installed in various SEIKO EPSON printers and network interfaces. The presence of this vulnerability poses a significant risk to organizations utilizing these devices.
With a CVSS score of 4.8, this vulnerability is classified as medium severity. The implications of this vulnerability are not trivial, as it can lead to unauthorized access and manipulation of printer settings, potentially impacting document confidentiality and integrity. Organizations should assess their exposure and take immediate action to mitigate this vulnerability.
The urgency for defenders is high, given that an attacker only needs administrative access to exploit this vulnerability. Organizations should prioritize patching immediately to prevent any potential exploitation, especially in environments where sensitive information may be printed or processed.
While there are currently no known exploits for this vulnerability, the potential for exploitation exists if administrative access is gained. Organizations must remain vigilant and monitor their systems for any indicators of compromise.
Vulnerability Details
According to the official CVE description, the vulnerability enables a remote authenticated attacker with administrative privileges to inject scripts into the Web Config of SEIKO EPSON printers. The CVSS vector indicates that the attack can be initiated over the network, requiring low complexity and high privileges, with user interaction necessary to execute the attack. The potential impacts include low confidentiality and integrity effects, but no availability impact.
The CWE classification associated with this vulnerability is CWE-79, indicating that it falls under the category of improper neutralization of input during web page generation ('Cross-site Scripting').
Technical Analysis
The root cause of CVE-2023-23572 is the failure to properly sanitize user input in the Web Config interface, which allows an attacker to inject malicious scripts. This vulnerability can be exploited through a network attack vector, requiring the attacker to have high privileges, specifically administrative access, to the printer's Web Config settings.
Attack complexity is low, as the vulnerability can be exploited with minimal technical skill once administrative access is obtained. User interaction is required to activate the malicious script, which could lead to various malicious activities, including data theft or unauthorized control of the printer.
The impacts on confidentiality and integrity are low, as the attacker may manipulate or capture data processed by the printer. However, the availability of the device remains unaffected.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-23572 is significant for organizations that rely on SEIKO EPSON printers. The ability for an authenticated attacker to inject scripts can lead to unauthorized access to sensitive information and potentially disrupt organizational operations. Given the medium severity rating, organizations should treat this vulnerability as a priority in their patch management processes.
The blast radius of this vulnerability is potentially large, especially in environments where multiple printers are deployed. An attacker exploiting this vulnerability could gain footholds across multiple devices, leading to broader network implications. The urgency for remediation is underscored by the need to safeguard sensitive data and maintain operational integrity.
Organizations should address this vulnerability in their priority patch cycle, especially if they operate environments with administrative access to the affected printers. Regular monitoring for signs of compromise and ensuring that printers are configured securely are essential defensive measures.

Affected Versions
The affected versions include various firmware for SEIKO EPSON printers, notably including lp-9200ps2, lp-9200ps3, lp-8200c, lp-9600, lp-8500c, and more. Organizations should ensure that all devices are updated to the latest firmware versions to mitigate this vulnerability. If version information is missing, it is advised to consider all versions prior to the vendor patch as vulnerable.
Mitigation & Remediation
Organizations should prioritize patching their SEIKO EPSON printers by applying the latest firmware updates as provided by the vendor. Detailed mitigation steps can be found in the vendor advisory available at Epson’s support page. In cases where immediate patching is not feasible, organizations should implement access controls to restrict administrative access and monitor for unusual activities on the printers.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for indicators of unauthorized access and script injections. Behavioral anomalies in printer operations, such as unexpected configuration changes or unusual print job patterns, should also be investigated.
