CVE-2015-7899
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 · uneditedThe com_content component in Joomla! 3.x before 3.4.5 does not properly check ACLs, which allows remote attackers to obtain sensitive information via unspecified 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 confidenceThe com_content component in Joomla! versions 3.x before 3.4.5 has an ACL (Access Control List) bypass vulnerability that allows remote attackers to access sensitive information without proper authorization checks.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate the Joomla installation directoryIdentify the web root directory where Joomla is installed. Look for typical Joomla files such as 'index.php', 'configuration.php', or the 'administrator' folder in the web root.Affected if Joomla is not present on the system, then this CVE does not apply.
-
Determine the installed Joomla versionCheck the version file typically found at /libraries/cms/version.php or review the manifest file in /administrator/manifests/files/joomla.xml. The version number is defined as a constant in these files.Affected if The exact version cannot be determined from the installation.
-
Compare the installed version against the affected rangeThe affected versions are: 3.2.0, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.3.0, 3.3.1, 3.3.2, 3.3.3, 3.3.4, 3.4.0, and 3.4.1. Match your installed version against this list.Affected if The installed version matches any version in the affected list (3.2.0 through 3.4.1).
-
Verify the com_content component is present and enabledCheck for the com_content component directory at /components/com_content/ and verify it is not disabled in the Joomla administrator components management or database #__extensions table.Affected if The com_content component is absent or explicitly disabled in the Joomla extension management.
A system is affected by this CVE if it is running Joomla versions 3.2.0 through 3.4.1 and the com_content component is installed and enabled.
