Linux Debian vulnerability analysis and mitigation

Overview

An issue in dc2niix before v.1.0.20240202 allows a local attacker to execute arbitrary code via the generated file name that is not properly escaped and injected into a system call when certain types of compression are used (NVD).

Technical details

The vulnerability is classified as an Improper Encoding or Escaping of Output (CWE-116) issue. The CVSS v3.1 score is 7.8 (High) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local access required with low attack complexity and privilege requirements, no user interaction needed, and high impacts on confidentiality, integrity, and availability (NVD).

Impact

The vulnerability allows local attackers to execute arbitrary code through improperly escaped filenames during compression operations. This could lead to complete system compromise with high impacts on confidentiality, integrity, and availability of the affected system (NVD).

Mitigation and workarounds

Users should upgrade to dc2niix version 1.0.20240202 or later which contains the fix for this vulnerability. The fix prevents shell expansion and possible command execution when shell expansion characters exist in the output file name (GitHub PR).
