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 SPPA-T3000 Application Server (All versions < Service Pack R8.2 SP2). An attacker with network access to the Application Server could gain access to path and filenames on the server by sending specifically crafted packets to 1099/tcp. Please note that an attacker needs to have network access to the Application Server in order to exploit this vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.

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

A path disclosure vulnerability in SPPA-T3000 Application Server allows remote attackers to obtain file paths and filenames by sending crafted packets to TCP port 1099. This is an information disclosure issue rather than code execution, but the exposed path information could aid further attacks.

MitigationApply vendor patch Service Pack R8.2 SP2 or later to upgrade the SPPA-T3000 Application Server. Additionally, restrict network access to port 1099/tcp to only trusted IPs using firewalls or network segmentation.

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 SPPA-T3000 Application Server installation
    Locate Siemens SPPA-T3000 software on the system by checking for installation directories, running services, or Siemens-related processes. Common locations include C:\Program Files\Siemens\ or /opt/siemens/ on Linux systems.
    Affected if The SPPA-T3000 Application Server software is found on the system
  2. Determine installed version
    Check the installed version of SPPA-T3000 Application Server. Consult the software documentation or check version information within the application or installation directory.
    Affected if The installed version is r8.2 or any version lower than r8.2 (versions < r8.2 or = r8.2)
  3. Verify TCP port 1099 status
    Check if TCP port 1099 is listening on the system. Use netstat, ss, or equivalent network tooling to list listening ports and confirm port 1099 is active.
    Affected if TCP port 1099 is open and listening
  4. Assess network exposure of port 1099
    Determine if port 1099 is accessible from network locations. Verify firewall rules, network ACLs, or binding configurations that control who can reach port 1099.
    Affected if Port 1099 is accessible from untrusted network segments or the internet

The environment is affected if SPPA-T3000 Application Server is installed with version r8.2 or lower AND TCP port 1099 is exposed to untrusted network access.
