Config::IniFiles versions before 3.001000 for Perl allow OS command injection and file overwrite via a 2-arg open() of the -file argument in _make_filehandle

03 Exploitation and scoring

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

1.06% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 64.6% of scored records. A rank, not a probability.

NVD base score

8.6 (CVSS v3.x), scored by the NVD independently of the CNA.

NVD CVSS vector

NVD analysis status

Deferred. NVD last modified this record on 2026-07-23.

Red Hat severity

Moderate. Red Hat's rating for its own products, not a CVSS rating.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation

Upgrade to Config::IniFiles 3.001000 or later, which opens the -file argument with a 3-arg read open so the filename is never interpreted as a command or redirect.
