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
A vulnerability has been identified in SICAM MMU (All versions < V2.05), SICAM SGU (All versions), SICAM T (All versions < V2.18). A stored Cross-Site-Scripting (XSS) vulnerability is present in different locations of the web application. An attacker might be able to take over a session of a legitimate user.

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

A stored Cross-Site-Scripting (XSS) vulnerability exists in the web interfaces of SICAM MMU (versions < V2.05), SICAM SGU (all versions), and SICAM T (versions < V2.18). Malicious scripts can be persistently injected into various web application locations and executed in browsers of legitimate users, potentially allowing session hijacking.

MitigationUpgrade to SICAM MMU V2.05 or later, SICAM T V2.18 or later (SGU requires contacting vendor for patch availability). Alternatively, implement robust input validation and output encoding on all user-supplied data fields in the web application.

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 deployed SICAM product
    Access the device management interface or system information page to determine which SICAM product is installed: MMU, SGU, or T
    Affected if The product is SICAM MMU, SICAM SGU, or SICAM T (any of the three affected product lines)
  2. Check the firmware version
    Locate the firmware version information in the product's web interface, system settings, or device management console. Compare your installed version against the affected ranges: SICAM MMU < V2.05, SICAM SGU (all versions), SICAM T < V2.18
    Affected if The installed version falls within: MMU versions below 2.05, any SGU version, or T versions below 2.18
  3. Verify if the web interface is enabled
    Check the product configuration or network settings to determine whether the web-based management interface is accessible and active
    Affected if The web interface is enabled and accessible (the XSS only affects web interfaces)
  4. Review web application logs for injected scripts
    Examine the web server logs or application logs for any unusual script tags, JavaScript code, or HTML elements that may have been injected into user-supplied fields such as device names, descriptions, or configuration parameters
    Affected if Suspicious script content appears in logs or in stored configuration fields

You are affected if you have SICAM MMU firmware below V2.05, any SICAM SGU version, or SICAM T firmware below V2.18, and the web interface is enabled.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to 2.05 / 2.18 or later
Fixed in 2.052.18
Interim mitigation

Upgrade to SICAM MMU V2.05 or later, SICAM T V2.18 or later (SGU requires contacting vendor for patch availability). Alternatively, implement robust input validation and output encoding on all user-supplied data fields in the web application.
