CVE-2012-1611
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 · uneditedJoomla! 2.5.x before 2.5.4 does not properly check permissions, which allows attackers to obtain sensitive "administrative back end" information via unknown attack vectors. NOTE: this might be a duplicate of CVE-2012-1599.
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 confidenceJoomla! 2.5.x before 2.5.4 contains a permission checking flaw that allows unauthorized users to access sensitive administrative backend information. The vulnerability stems from improper validation of user permissions before disclosing backend data.

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.
-
Identify the installed Joomla versionAccess the Joomla administration backend and look for the version number in the Help menu > System Info, or check the version.php file in the Joomla installation directory.Affected if The version displayed is 2.5.0, 2.5.1, 2.5.2, or 2.5.3.
-
Verify user account privilegesReview the user groups and their assigned permissions in the Joomla admin console under Users > Groups. Identify if any user group has limited or frontend-only access that should not view backend administrative data.Affected if There exist user accounts in groups with restricted permissions that should not have backend access.
-
Test backend access with low-privilege accountsUsing a test user account that is NOT assigned to Super Administrator or Administrator groups, attempt to access administrative backend URLs or components directly (such as /administrator/ or admin component URLs).Affected if The low-privilege user can view or retrieve administrative backend information that should be restricted.
The environment is affected if Joomla version 2.5.0 through 2.5.3 is installed and unauthorized users can access administrative backend data due to the permission checking flaw.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Joomla! 2.5.4 or later which contains the corrected permission checking logic. Review user group permissions in the admin console after upgrading.
