CVE-2025-7746 is a Cross-site Scripting (XSS) vulnerability classified under CWE-79 affecting Schneider Electric's Altivar Process Drives series, specifically models ATV630, ATV650, ATV660, ATV680, ATV6A0, ATV6B0, and ATV6L0. This vulnerability arises from improper neutralization of input during web page generation, allowing an attacker to inject malicious scripts into the web interface of these industrial drives. Since all versions of these products are affected, any deployment of these drives with their web management interface exposed could be vulnerable. The vulnerability does not require authentication or privileges to exploit and only requires user interaction, such as a victim visiting a maliciously crafted web page or link. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but requiring user interaction. Exploitation could allow an attacker to execute arbitrary scripts in the context of the victim’s browser session when interacting with the device’s web interface. This could lead to theft of sensitive information, session hijacking, or manipulation of displayed data, potentially misleading operators or causing incorrect operational decisions. While no known exploits are currently in the wild, the vulnerability’s presence in critical industrial control equipment raises concerns about potential targeted attacks. The lack of available patches at the time of publication increases the urgency for mitigation and monitoring.

For European organizations, especially those in manufacturing, utilities, and critical infrastructure sectors that rely on Schneider Electric’s Altivar Process Drives, this vulnerability poses a risk to operational integrity and information confidentiality. Successful exploitation could allow attackers to manipulate or steal data viewed by operators, potentially leading to incorrect control commands or delayed responses to operational issues. This could disrupt production lines, cause equipment damage, or lead to safety incidents. Additionally, compromised operator sessions could be leveraged for further lateral movement within industrial control networks. Given the widespread use of Schneider Electric products across Europe, the vulnerability could affect a broad range of industries, including automotive manufacturing, energy production, water treatment, and chemical processing. The medium severity rating indicates that while the vulnerability is not immediately critical, the potential for targeted attacks in high-value industrial environments elevates its importance. The absence of known exploits currently provides a window for proactive defense but also suggests that attackers may develop exploits in the future.

Since no official patches are currently available, European organizations should implement compensating controls to reduce exposure. These include restricting access to the web interfaces of affected Altivar drives by network segmentation and firewall rules, allowing only trusted management stations to connect. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting the drives’ web interfaces can help mitigate injection attempts. Operators should be trained to recognize phishing or social engineering attempts that could lead to user interaction with malicious payloads. Regular monitoring and logging of web interface access should be enhanced to detect anomalous activities. Organizations should also engage with Schneider Electric for updates on patch releases and apply them promptly once available. Additionally, consider disabling or limiting web interface functionality if not required for daily operations. Implementing multi-factor authentication on management interfaces, if supported, can further reduce risk. Finally, conducting internal penetration testing focusing on the drives’ web interfaces can help identify and remediate environment-specific weaknesses.
