CVE-2023-6027
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 · uneditedA critical flaw has been identified in elijaa/phpmemcachedadmin affecting version 1.3.0, specifically related to a stored XSS vulnerability. This vulnerability allows malicious actors to insert a carefully crafted JavaScript payload. The issue arises from improper encoding of user-controlled entries in the "/pmcadmin/configure.php" parameter.
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 confidenceA stored cross-site scripting (XSS) vulnerability exists in elijaa/phpmemcachedadmin version 1.3.0 within the configure.php file. User-supplied input to certain parameters is not properly encoded before being stored and rendered, allowing injection of malicious JavaScript payloads that execute in the context of other users' sessions.

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 if phpmemcachedadmin is installedLocate the configure.php file in your web root or application directory. Common paths include /phpmemcachedadmin/configure.php or similar paths under your web server document root.Affected if The configure.php file from elijaa/phpmemcachedadmin exists in your environment.
-
Confirm the installed versionCheck the version of phpmemcachedadmin by examining the composer.json file, README file, or any version file included in the application distribution. Compare your version against 1.3.0.Affected if Your installed version is exactly 1.3.0.
-
Verify configure.php is accessibleCheck if the configure.php script is accessible via your web server by attempting to access it through a browser or via curl/http request to the known URL path.Affected if The configure.php file is accessible over HTTP/HTTPS and accepts user input.
-
Inspect stored configuration for unsanitized inputExamine any saved configuration data or configuration files created by the application. Look for user-supplied values that may have been saved through the configure.php interface without proper encoding.Affected if Configuration parameters contain raw user input that has not been HTML-encoded.
You are affected if phpmemcachedadmin version 1.3.0 is installed and the configure.php file is accessible and accepts user-supplied input that gets stored and rendered without encoding.

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 dataImplement proper input validation and output encoding for all user-controlled parameters in configure.php, using context-appropriate encoding (HTML entity encoding for HTML content) to neutralize XSS payloads.
