CVE-2014-10401: An issue was discovered in the DBI module before 1.632 for Perl.

An issue was discovered in the DBI module before 1.632 for Perl. DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute.

Security readout for executives and security teams

Plain-English summary

This is an old Perl DBI flaw affecting versions before 1.632. Some file-backed database drivers could read files outside the directory an application intended to allow. Business risk depends on whether a Perl application uses DBD::File-style drivers and exposes file or table selection to less-trusted users.

Executive priority

Treat this as a targeted legacy dependency cleanup item, not an emergency, unless critical Perl applications use file-backed DBI drivers with untrusted input. Prioritize inventory and upgrade during normal remediation windows, escalating if sensitive files could be reachable.

Technical view

CVE-2014-10401 is a directory restriction bypass in Perl DBI DBD::File drivers. The f_dir attribute did not fully constrain opened files, allowing access outside the configured folder. The source bundle identifies DBI before 1.632 as affected and points to the upstream fix and Ubuntu advisory.

Likely exposure

Exposure is most likely in legacy Perl applications using DBI with DBD::File drivers, especially where user input influences file-backed tables. Systems with DBI 1.632 or vendor-patched packages are less likely exposed. The provided data does not identify affected CPEs.

Exploitation context

The source bundle does not show KEV listing, public exploitation, or active exploitation. The issue appears to require an application path where DBI file-backed driver behavior can be influenced. Impact is mainly unintended local file access outside an expected directory boundary.

Researcher notes

Key evidence is limited but consistent: the CVE description, upstream commit, DBI 1.632 changelog, CPAN bug, and Ubuntu advisory all point to a DBD::File directory confinement flaw. No CVSS, CWE, CPE, or exploitation evidence is provided.

Mitigation direction

  • Upgrade Perl DBI to version 1.632 or later where feasible.
  • Apply vendor-supported packages referenced by applicable distribution advisories.
  • Review applications using DBD::File drivers and the f_dir attribute.
  • Restrict service account filesystem permissions to only required directories.
  • Check current vendor guidance before deploying compensating controls.

Validation and detection

  • Inventory installed Perl DBI versions across servers and build images.
  • Search application dependencies for DBI and DBD::File driver usage.
  • Review code paths where user input influences file-backed table names or paths.
  • Confirm vendor package versions include the CVE-2014-10401 fix.
  • Add regression tests for intended file-directory confinement where applicable.
