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 · unedited
An issue was discovered in EnterpriseDB Postgres Advanced Server (EPAS) before 11.21.32, 12.x before 12.16.20, 13.x before 13.12.16, 14.x before 14.9.0, and 15.x before 15.4.0. It contains the functions get_url_as_text and get_url_as_bytea that are publicly executable, thus permitting an authenticated user to read any file from the local filesystem or remote system regardless of that user's permissions.

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 confidence

EnterpriseDB Postgres Advanced Server contains two functions (get_url_as_text and get_url_as_bytea) that are publicly executable, allowing any authenticated database user to read arbitrary files from the local filesystem or remote systems. This is an authorization bypass where function-level security is not properly enforced.

MitigationUpdate EPAS to the patched versions (11.21.32, 12.16.20, 13.12.16, 14.9.0, or 15.4.0). As a compensating control, revoke public execute permissions on these functions until patching is completed.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm EnterpriseDB Postgres Advanced Server is installed
    Look for EPAS binaries or service. On Linux check /opt/edb/as<x>/bin/ for psql or edb-psql, or run 'which edb-psql' or check for running 'edb-as-<version>' processes.
    Affected if EPAS is installed on the system
  2. Identify installed EPAS version
    Run 'psql --version' or 'edb-psql --version' from the EPAS bin directory, or query SELECT version(); from a database connection.
    Affected if Version is < 11.21.32, or >= 12.0.0 and < 12.16.20, or >= 13.0.0 and < 13.12.17, or >= 14.0.0 and < 14.9.0, or >= 15.0.0 and < 15.4.0
  3. Check if vulnerable functions exist
    Query the pg_proc catalog: SELECT proname FROM pg_proc WHERE proname IN ('get_url_as_text','get_url_as_bytea');
    Affected if Either function exists in the database
  4. Check function execute permissions
    Query function permissions: SELECT proname, proacl FROM pg_proc WHERE proname IN ('get_url_as_text','get_url_as_bytea'); or check if PUBLIC has execute: SELECT proname, proacl::text FROM pg_proc WHERE proname IN ('get_url_as_text','get_url_as_bytea') AND proacl::text LIKE '%=X/%' OR proacl::text LIKE '%=X*%' OR proacl::text LIKE '%PUBLIC%';
    Affected if PUBLIC or unauthenticated roles have EXECUTE permission on either function

A user is affected if they run a vulnerable EPAS version AND the get_url_as_text or get_url_as_bytea functions exist with PUBLIC execute permissions, allowing any authenticated database user to read arbitrary local or remote files.

Upgrade available Upgrade to 11.21.32 / 12.16.20 / 13.12.17 or later
Fixed in 11.21.3212.16.2013.12.17
Interim mitigation

Update EPAS to the patched versions (11.21.32, 12.16.20, 13.12.16, 14.9.0, or 15.4.0). As a compensating control, revoke public execute permissions on these functions until patching is completed.

Recommended fix High confidence

Upgrade to EPAS 11.21.32, 12.16.20, 13.12.16, 14.9.0, or 15.4.0 depending on your current major version branch

  1. Identify the current EPAS version by running: psql --version or SELECT version();
  2. Plan and schedule a maintenance window for the upgrade
  3. Perform a full backup of all databases before upgrading
  4. Upgrade to the fixed version: 11.21.32 (for v11), 12.16.20 (for v12), 13.12.16 (for v13), 14.9.0 (for v14), or 15.4.0 (for v15)
  5. After upgrade, verify the get_url_as_text and get_url_as_bytea functions are no longer publicly executable by checking permissions
Caveat Standard database upgrade considerations apply - test in staging first, review release notes for backward compatibility notices
