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
Unspecified vulnerability in Interchange before 5.6.0 and before 5.5.2 allows remote attackers to cause a denial of service via crafted HTTP requests. NOTE: this might overlap CVE-2007-2635.

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

Interchange (an e-commerce web application) before versions 5.6.0 and 5.5.2 contains an unspecified vulnerability that allows remote attackers to cause denial of service via crafted HTTP requests. The vulnerability can be exploited remotely without authentication.

MitigationUpgrade Interchange to version 5.6.0 or 5.5.2 or later to remediate this vulnerability. If immediate upgrading is not possible, consider restricting HTTP access to the application via network-level controls or a WAF.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Locate Interchange installation
    Check for the interchange binary or control script. Common paths include /usr/bin/interchange, /usr/local/bin/interchange, or /opt/interchange/bin/interchange. On Linux, also run: rpm -qa | grep -i interchange or dpkg -l | grep -i interchange
    Affected if Interchange is not found on the system (not vulnerable because not installed)
  2. Determine installed Interchange version
    Run the interchange binary with version flag, such as: interchange --version or interchangectl --version. If installed via package manager, use: rpm -q interchange or dpkg -s interchange
    Affected if The version returned is 4.8.0, 4.8.1, 4.8.2, 4.8.3, 4.8.4, 4.8.5, 4.8.6, 4.8.7, 4.8.8, 4.8.9, 4.9.3, or 4.9.4
  3. Verify HTTP access is enabled
    Check if Interchange is configured to accept HTTP connections. Look for HTTP server configuration in interchange.cfg or catalog.cfg files. Check if the server is bound to a network interface (default port 7786 for demo, or 80/443 for production). Commands: netstat -tlnp | grep -E '(7786|80|443)' or ss -tlnp | grep -E '(7786|80|443)'
    Affected if Interchange is listening on a network port and accessible via HTTP (required for remote exploitation)
  4. Check for unauthenticated HTTP endpoints
    Review the Interchange catalog configuration for any publicly accessible endpoints. Examine catalog.cfg for [catalog] sections that expose pages without authentication. Inspect the www/ directory for HTML or/or pages that are served without requiring login
    Affected if Unauthenticated HTTP endpoints are exposed to the network (exploitation does not require authentication)

If Interchange is installed and running with an affected version (4.8.x or 4.9.3-4.9.4) while listening on an HTTP port accessible over the network, the environment is vulnerable to remote denial of service via crafted HTTP requests.

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

Upgrade Interchange to version 5.6.0 or 5.5.2 or later to remediate this vulnerability. If immediate upgrading is not possible, consider restricting HTTP access to the application via network-level controls or a WAF.

Recommended fix High confidence

Interchange 5.6.0 or later (or 5.5.2 or later)

  1. 1. Identify the current Interchange version by checking the version file or running 'interchange --version'
  2. 2. Back up the entire Interchange installation directory and database
  3. 3. Download the fixed Interchange version 5.6.0 or later (or 5.5.2 or later) from the official ICdevgroup repository
  4. 4. Stop the Interchange server daemon
  5. 5. Install the new version following the standard Interchange upgrade procedure
  6. 6. Start the Interchange server and verify it is running correctly
  7. 7. Test that the web application functions normally after the upgrade
Caveat Upgrading across major version branches may introduce compatibility changes; review the release notes for any breaking changes between your current version and the target version
