CVE-2014-10402: An issue was discovered in the DBI module through 1.643 for Perl.

An issue was discovered in the DBI module through 1.643 for Perl. DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute in the data source name (DSN). NOTE: this issue exists because of an incomplete fix for CVE-2014-10401.

Security readout for executives and security teams

Plain-English summary

CVE-2014-10402 affects Perl's DBI module through 1.643. In some DBD::File driver use cases, file access restrictions based on the f_dir DSN attribute can be bypassed, allowing files outside the intended folder to be opened. The sources do not provide CVSS, CWE, or confirmed exploitation evidence.

Executive priority

Prioritize systems where Perl DBI file-backed drivers process untrusted input or protect sensitive local files. With no CVSS or exploitation evidence in the sources, urgency should be driven by actual application exposure and data sensitivity.

Technical view

DBD::File drivers in DBI through 1.643 can open files outside folders explicitly supplied via f_dir in the DSN. The CVE states this resulted from an incomplete fix for CVE-2014-10401. Impact depends on whether applications use affected file-backed DBI drivers and whether attacker-controlled input can influence file or table selection.

Likely exposure

Exposure is most likely in Perl applications or scripts using DBI DBD::File-style drivers with f_dir as a security boundary. Systems relying only on database engines unrelated to DBD::File are not shown as affected by the provided sources.

Exploitation context

The source bundle does not cite active exploitation, and KEV status is false. Practical risk depends on local application design, file permissions, and whether untrusted users can influence DBI file-backed data sources.

Researcher notes

This CVE is tied to an incomplete fix for CVE-2014-10401. The public record in the provided bundle is sparse: no CVSS vector, CWE, exploit status, or universal fixed version is supplied. Validate exposure through code and package review rather than product-name assumptions.

Mitigation direction

  • Inventory Perl DBI installations and identify versions through 1.643.
  • Apply the Debian libdbi-perl security update where relevant.
  • For non-Debian systems, check CPAN or vendor guidance for fixed DBI releases.
  • Do not rely on f_dir alone as a security boundary.
  • Restrict filesystem permissions for application users running affected Perl code.

Validation and detection

  • Confirm whether applications use DBI with DBD::File-backed drivers.
  • Check installed DBI package versions against the affected range.
  • Review DSN construction for f_dir usage and user-controlled inputs.
  • Verify OS-level permissions limit access to sensitive files.
  • Confirm applicable vendor or distro security updates are installed.
