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
MMP: All versions prior to v1.0.3, PTP C-series: Device versions prior to v2.8.6.1, and PTMP C-series and A5x: Device versions prior to v2.5.4.1 does not properly sanitize user input, which may allow an attacker to perform a SQL injection and obtain sensitive information.

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 · high confidence

SQL injection vulnerability in multiple Cambium Networks product lines (MMP, PTP C-series, PTMP C-series and A5x) due to improper user input sanitization. Attackers can exploit this to inject malicious SQL queries and extract sensitive data from the database.

MitigationApply vendor-provided patches: upgrade MMP to v1.0.3+, PTP C-series to v2.8.6.1+, and PTMP C-series/A5x to v2.5.4.1+. If patching is not immediately possible, audit and restrict network access to these devices to reduce attack surface.

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 Airspan Mimosa Management Platform (MMP) version
    Log into the MMP web interface and navigate to the About or System Information page. Alternatively, access the MMP server via SSH and run: cat /opt/mimosa/mmp/version or check the installed package version.
    Affected if MMP version is lower than 1.0.3 and the web interface is accessible
  2. Identify Airspan C5x or C5c firmware version
    Log into the device web interface and check the Status or System page for firmware version. Alternatively, access via CLI (SSH/Telnet) and run: show system info or firmware show.
    Affected if Firmware version is lower than 2.8.6.1 and the web interface is accessible
  3. Identify Airspan C6x firmware version
    Log into the C6x device web interface and check the System or About page. Alternatively, access via CLI and run: show version or show system details.
    Affected if Firmware version is lower than 2.8.6.1 and the web interface is accessible
  4. Identify Airspan A5x firmware version
    Log into the A5x device web interface and navigate to Status or System Information. Alternatively, access via CLI and run: show system or cat /proc/version if available.
    Affected if Firmware version is lower than 2.5.4.1 and the web interface is accessible
  5. Verify management interface accessibility
    Determine if the web-based management interface (HTTP/HTTPS) for the identified product is exposed to the network. Check firewall rules, NAT configurations, or VLAN settings that may allow external access.
    Affected if The management interface is reachable from untrusted networks (such as the internet or guest VLANs)

You are affected if any Airspan MMP, C5x, C5c, C6x, or A5x device in your environment is running a version below the specified thresholds AND its web management interface is network-accessible.

Fixed in 1.0.32.5.4.12.8.6.1
Interim mitigation

Apply vendor-provided patches: upgrade MMP to v1.0.3+, PTP C-series to v2.8.6.1+, and PTMP C-series/A5x to v2.5.4.1+. If patching is not immediately possible, audit and restrict network access to these devices to reduce attack surface.

Recommended fix High confidence

MMP v1.0.3, C6x/C5x/C5c firmware v2.8.6.1, A5x firmware v2.5.4.1

  1. Identify the specific Mimosa product in use (MMP, C6x, C5x, C5c, or A5x)
  2. Access the device management interface or MMP admin console
  3. Verify the current firmware/software version
  4. Download the appropriate fixed version from Mimosa's official support channels: MMP v1.0.3, C6x/C5x/C5c firmware v2.8.6.1, or A5x firmware v2.5.4.1
  5. Follow the standard firmware upgrade procedure via the web interface or management console
  6. After upgrade, verify the new version is installed and the SQL injection vulnerability is remediated
