CVE-2023-2544
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 · uneditedAuthorization bypass vulnerability in UPV PEIX, affecting the component "pdf_curri_new.php". Through a POST request, an authenticated user could change the ID parameter to retrieve all the stored information of other registered users.
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 · high confidenceThis is an IDOR (Insecure Direct Object Reference) authorization bypass in UPV PEIX's pdf_curri_new.php component. An authenticated attacker can manipulate the ID parameter in a POST request to access sensitive curriculum/educational records belonging to other users, due to missing or inadequate ownership verification before data retrieval.

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 vulnerable php fileSearch the web server filesystem for pdf_curri_new.php within the UPV PEIX application directory structureAffected if The file exists and is accessible via the web application
-
Verify the ID parameter is accepted in POST requestsInspect the pdf_curri_new.php code to confirm it accepts an ID parameter via POST method for curriculum record retrievalAffected if The component processes an ID parameter from POST requests without explicit authorization validation
-
Confirm absence of ownership verification logicReview the source code of pdf_curri_new.php for functions that verify the authenticated user matches the record owner before returning dataAffected if No code exists that validates the requester's identity against the requested record's owner prior to data retrieval
-
Check for predictable ID valuesTest the endpoint with different ID values while authenticated to observe if sequential or predictable IDs grant access to other users recordsAffected if Different ID values return curriculum data belonging to users other than the authenticated account
A user is affected if pdf_curri_new.php exists, processes POST requests with an ID parameter, and returns curriculum records without verifying the authenticated user owns or has permission to access that specific record.

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 authorization checks in pdf_curri_new.php to verify the authenticated user owns or has permission to access the requested record before returning any data. Validate user session and compare requester identity against the requested resource owner.
