CVE-2018-12807
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 · uneditedAdobe Experience Manager versions 6.4, 6.3, 6.2, 6.1, and 6.0 have an input validation bypass vulnerability. Successful exploitation could lead to unauthorized information modification.
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 confidenceAdobe Experience Manager versions 6.0-6.4 contain an input validation bypass vulnerability that allows attackers to circumvent standard input sanitization checks. This could enable unauthorized modification of information through specially crafted input that evades validation controls.

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 installed AEM versionAccess the AEM Web Console (system/console/systeminfo) or check the version.properties file in the crx-quickstart folder. The version is typically displayed on the 'Welcome' page of AEM under 'Version Information'.Affected if The installed version falls within: 6.1.2.1 to 6.1.2.16 inclusive, 6.2.1.1 to 6.2.1.15 inclusive, or exactly 6.3.2.1
-
Confirm AEM 6.x core platformVerify the product is Adobe Experience Manager by checking for the AEM logo in the UI or by querying the JMX console for 'Adobe Experience Manager' in the product name.Affected if The product is confirmed as Adobe Experience Manager versions 6.0 through 6.4 but the version check above does not match the affected ranges - however note the summary indicates 6.0 is mentioned but no specific 6.0.x version range is provided, so the safest assumption is any 6.1.2.x, 6.2.1.x, or 6.3
-
Verify input validation is in useCheck for the presence of custom input validation rules in /apps or /libs paths, particularly in servlet filters, XSS protection configurations, or Granite data validation modules. Review any custom sling:resourceType components that process user input.Affected if Custom input validation or sanitization logic is implemented in the AEM instance, as the vulnerability allows bypass of these controls - if no validation exists there is nothing to bypass (though the security exposure still exists)
-
Inspect XSS filter configurationNavigate to the Apache Felix Web Console Configuration (system/console/config) and locate the XSSAPI configuration orgranite.forms.commons.validation configuration. Check if XSS protection rules are explicitly defined.Affected if XSS or input sanitization filters are enabled in the AEM configuration, as the bypass would affect these protective controls
The environment is affected if Adobe Experience Manager version 6.1.2.1 through 6.1.2.16, 6.2.1.1 through 6.2.1.15, or exactly 6.3.2.1 is installed and the application uses any form of input validation or sanitization that could be bypassed.

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 dataApply the appropriate AEM security patch or hotfix provided by Adobe for this vulnerability. Additionally, implement robust input validation at all application entry points and review existing validation logic for bypass opportunities.
