Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Schweitzer Engineering Laboratories Real-Time Automation Controller (SEL RTAC) Web Interface could allow a remote authenticated attacker to inject and execute arbitrary script code. See SEL Service Bulletin dated 2022-11-15 for more details.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a stored/reflected Cross-Site Scripting (XSS) vulnerability in the Schweitzer Engineering Laboratories Real-Time Automation Controller (SEL RTAC) web interface. An authenticated remote attacker can inject malicious JavaScript or other script code into web pages served by the RTAC device, which will execute in the browsers of other authenticated users who view the compromised content.

MitigationApply the vendor patch from SEL Service Bulletin (2022-11-15) to the affected RTAC firmware. Until then, restrict web interface access to trusted users only and monitor for suspicious activity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the SEL RTAC model number
    Locate the model label on the physical device or check the web interface system information page for the exact model (e.g., SEL 2241, SEL 3350, SEL 3505, SEL 3530, SEL 3532, SEL 3555)
    Affected if The model is one of the affected products listed in the CVE
  2. Determine the installed firmware version
    Access the RTAC web interface and navigate to the system settings or about page to view the firmware version, or use the device CLI to query the firmware version
    Affected if The firmware version cannot be determined or is not visible
  3. Compare firmware version against affected ranges
    Check if your firmware version falls within any of the following ranges: r113-v0 to r149 (for SEL 2241), r148-v0 to r149 (for SEL 3350), r119-v0 to r149 (for SEL 3505), r132-v0 to r149 (for SEL 3505 3), r100-v0 to r149 (for SEL 3530), r108-v0 to r149 (for SEL 3530 4), r132-v0 to r149 (for SEL 3532), or r134-v0 to r149 (for SEL 3555)
    Affected if The installed version is greater than or equal to the minimum affected version and less than r150-v2 for your model
  4. Verify the web interface is accessible
    Attempt to access the RTAC web interface via HTTP/HTTPS to confirm it is enabled and reachable on the network
    Affected if The web interface is enabled and exposed
  5. Check for unexpected content in web interface
    Review web interface logs or user-generated content areas for any suspicious script tags or unexpected HTML/JavaScript that was not authored by administrators
    Affected if Unexpected script content is found in logs or stored content

You are affected if your SEL RTAC model matches one of the listed products AND your installed firmware version is within the vulnerable range (greater than or equal to the minimum version for your model but less than r150-v2), and the web interface is enabled.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the vendor patch from SEL Service Bulletin (2022-11-15) to the affected RTAC firmware. Until then, restrict web interface access to trusted users only and monitor for suspicious activity.

Recommended fix Moderate confidence

r150-v2 or later firmware

  1. Identify the specific SEL RTAC model (2241, 3350, 3505, 3505 3, 3530, 3530 4, 3532, or 3555) in use
  2. Access the SEL customer portal or contact SEL technical support to obtain firmware version r150-v2 or later
  3. Backup the current RTAC configuration
  4. Upload and install the r150-v2 (or later) firmware to the RTAC device
  5. Verify the firmware installation was successful
  6. Restore the configuration if needed
  7. Confirm the web interface is functioning properly
Caveat Ensure compatibility with other integrated systems before upgrading; review SEL Service Bulletin 2022-11-15 for any specific migration notes
