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
PaperThin CommonSpot before 7.0.2 and 8.x before 8.0.3 allows remote attackers to bypass intended access restrictions via a '\0' character, as demonstrated by using this character within a pathname on the drive containing the web root directory of a ColdFusion installation.

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

PaperThin CommonSpot before 7.0.2 and 8.x before 8.0.3 contains a null byte injection vulnerability that allows remote attackers to bypass access restrictions by embedding a '\0' character within file paths. This can enable unauthorized access to restricted directories or files within the ColdFusion web root.

MitigationUpgrade CommonSpot to version 7.0.2 or 8.0.3 or later to patch the null byte injection vulnerability. If immediate upgrade is not possible, implement input validation that strips or rejects null characters in all user-supplied file paths.

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 installed CommonSpot version
    Access the CommonSpot administration interface, typically at /commonspot//admin/ or check the footer of any CommonSpot page for the version number. Alternatively, inspect any version-related file in the ColdFusion web root (such as a version.cfm or info.cfm file).
    Affected if The version is 7.0.1 or earlier, or any of 8.0.0, 8.0.2, or 8.0.2.
  2. Confirm ColdFusion version and configuration
    Check the ColdFusion Administrator console or the cfusion/version.txt file to confirm the ColdFusion version powering CommonSpot.
    Affected if CommonSpot is running on any supported ColdFusion version with the vulnerable CommonSpot version installed.
  3. Locate CommonSpot installation directory
    Identify the ColdFusion web root directory where CommonSpot is installed. This is typically where the commonspot/ subdirectory resides.
    Affected if CommonSpot files are accessible within a web-accessible directory.
  4. Review file access handling
    Inspect CommonSpot handlers or scripts that process file paths (such as upload handlers or file inclusion scripts) for lack of null byte sanitization. Search for any use of file path variables without filtering the null character (0x00).
    Affected if The application processes user-supplied file paths without stripping or rejecting null bytes.
  5. Check for protected directory access
    Attempt to access a known restricted file or directory through a CommonSpot URL with a null byte appended (for example: /path/to/restricted/file.txt%00). If the server returns the file content rather than an access denied error, the vulnerability may be present.
    Affected if The server returns file content for paths that should be restricted when a null byte is embedded.

You are affected if your CommonSpot version is 7.0.1 or earlier, or 8.0.0 through 8.0.2, and the application handles file paths without null byte filtering.

From vendor data
Upgrade available Upgrade to a release after 7.0.1
Interim mitigation

Upgrade CommonSpot to version 7.0.2 or 8.0.3 or later to patch the null byte injection vulnerability. If immediate upgrade is not possible, implement input validation that strips or rejects null characters in all user-supplied file paths.
