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 Plone 2.5 through 4.0, as used in Conga, luci, and possibly other products, allows remote attackers to obtain administrative access, read or create arbitrary content, and change the site skin via unknown vectors.

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

Plone CMS versions 2.5 through 4.0 contain an unspecified vulnerability allowing remote unauthenticated attackers to gain administrative access, read/create arbitrary content, and modify site appearance. The vulnerability also affects Conga and luci products that use affected Plone versions.

MitigationUpgrade to a supported Plone version (4.1 or later for Plone 4 series, or preferably the latest stable release). For systems unable to upgrade immediately, restrict network access to Plone administrative interfaces and ensure Plone is not directly exposed to untrusted networks.

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 Plone installation and version
    Locate the Plone installation directory and check the version.py or version.txt file. Common paths include /opt/plone or /var/plone. Run 'python -c "import Plone; print(Plone.__version__)"' if Plone is importable, or check the 'Products.CMFPlone' egg version.
    Affected if The installed Plone version is 2.5, 2.5.1, 2.5.2, 2.5.3, 2.5.4, 2.5.5, 3.0, 3.0.1, 3.0.2, 3.0.3, 3.0.4, or 3.0.5, or falls within the 2.5-4.0 range.
  2. Check for Conga package presence
    Query the system package manager for installed Conga packages. On RPM-based systems run 'rpm -qa | grep -i conga'. On Debian-based systems run 'dpkg -l | grep -i conga'.
    Affected if Any version of Redhat Conga is installed.
  3. Check for Luci package presence
    Query the system package manager for installed Luci packages. On RPM-based systems run 'rpm -qa | grep -i luci'. On Debian-based systems run 'dpkg -l | grep -i luci'.
    Affected if Any version of Redhat Luci is installed.
  4. Verify Plone admin interface exposure
    Check network listeners on common Plone ports (8080, 8443, 80, 443). Run 'netstat -tlnp' or 'ss -tlnp' and look for Plone-serving processes. Review firewall rules and reverse proxy configurations that may expose the Zope/Plone management interface.
    Affected if The Plone administrative interface is reachable from untrusted networks without network access restrictions.

A system is affected if Plone version is any release from 2.5 through 3.0.5, or if either the Conga or Luci packages are installed, particularly when the admin interface is network-exposed.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to a supported Plone version (4.1 or later for Plone 4 series, or preferably the latest stable release). For systems unable to upgrade immediately, restrict network access to Plone administrative interfaces and ensure Plone is not directly exposed to untrusted networks.
