CVE-2026-3010 is a critical vulnerability classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-site Scripting (XSS), affecting Microchip's TimePictra software versions 11.0 through 11.3 SP2. TimePictra is an industrial automation software platform used for monitoring and control in manufacturing environments. The vulnerability arises because the application fails to properly sanitize or encode user-supplied input before embedding it into dynamically generated web pages. This flaw allows an unauthenticated attacker to craft malicious HTTP requests that inject executable scripts into the web interface. When a legitimate user accesses the compromised page, the injected script executes in their browser context, potentially allowing the attacker to steal sensitive information, manipulate session data, or perform unauthorized actions. The CVSS 4.0 base score of 9.3 reflects the vulnerability's network attack vector, no required privileges or user interaction, and high impact on confidentiality and integrity. The scope is limited to the affected TimePictra instances, but the vulnerability's ease of exploitation and critical impact make it a serious threat. No patches are currently linked, and no exploits have been observed in the wild, but the vulnerability is publicly disclosed and should be addressed promptly.

The exploitation of CVE-2026-3010 can have severe consequences for organizations relying on Microchip TimePictra for industrial automation and monitoring. Attackers can execute arbitrary scripts in the context of legitimate users, potentially leading to theft of sensitive operational data, unauthorized command execution, or manipulation of monitoring results. This compromises confidentiality and integrity, possibly disrupting manufacturing processes or causing erroneous system behavior. Since the vulnerability requires no authentication or user interaction, it can be exploited remotely by any attacker with network access to the TimePictra web interface. The availability impact is low, but the breach of trust and data integrity can lead to operational downtime, regulatory non-compliance, and financial losses. Organizations in critical infrastructure sectors using TimePictra are particularly vulnerable to targeted attacks aiming to disrupt industrial operations or conduct espionage.

1. Immediate mitigation should include restricting network access to the TimePictra web interface using firewalls or VPNs to limit exposure to trusted users only. 2. Implement Web Application Firewall (WAF) rules to detect and block common XSS attack patterns targeting TimePictra endpoints. 3. Enforce strict input validation and output encoding on all user-supplied data within the application, especially in web page generation contexts. 4. Monitor web server logs for unusual or suspicious HTTP requests that may indicate attempted exploitation. 5. Deploy Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks by restricting script execution sources. 6. Coordinate with Microchip for timely release and application of official patches or updates addressing this vulnerability. 7. Educate users and administrators about the risks of XSS and encourage vigilance when interacting with the TimePictra web interface. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities in industrial control systems.
