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
USVN (aka User-friendly SVN) before 1.0.10 allows attackers to execute arbitrary code in the commit view.

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

USVN (User-friendly SVN) versions before 1.0.10 contain a critical vulnerability in the commit view that allows unauthenticated attackers to execute arbitrary code on the server. The vulnerability is exploitable remotely with network access and carries a CVSS 9.8 rating due to the complete impact on confidentiality, integrity, and availability.

MitigationUpgrade USVN to version 1.0.10 or later to remediate the arbitrary code execution vulnerability. Until the upgrade is applied, restrict network access to the USVN interface.

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 USVN installation and locate version
    Check your web server document root for USVN installation directories. Look for a version file, changelog, or check the application's about/page for the version number.
    Affected if USVN is installed and the version cannot be determined or is below 1.0.10
  2. Verify USVN is accessible over network
    Confirm the USVN web interface is reachable by accessing its URL (typically at /usvn or similar path) from a browser or using curl to check HTTP response.
    Affected if The USVN web interface is exposed and responds to requests
  3. Confirm version is in vulnerable range
    Compare your installed USVN version to the affected range: any version before 1.0.10 is vulnerable.
    Affected if Your installed version is any release prior to 1.0.10 (e.g., 1.0.9, 1.0.8, etc.)
  4. Check if commit view functionality exists
    Access the commit view endpoint if known, or browse the USVN interface to confirm the commit viewing feature is present and functional.
    Affected if The commit view feature is accessible (required for exploitation)

You are affected if USVN is installed with a version lower than 1.0.10 and the web interface with its commit view is accessible over the network.

Upgrade available Upgrade to 1.0.10 or later
Fixed in 1.0.10
Interim mitigation

Upgrade USVN to version 1.0.10 or later to remediate the arbitrary code execution vulnerability. Until the upgrade is applied, restrict network access to the USVN interface.

Recommended fix Moderate confidence

1.0.10

  1. 1. Backup your current USVN installation and database before proceeding
  2. 2. Download USVN version 1.0.10 from the official source at www.usvn.info
  3. 3. Extract the new version and replace the existing installation files
  4. 4. Verify the upgrade was successful by accessing the USVN web interface
  5. 5. Test the commit view functionality to ensure proper operation
