DescriptionNVD

Profile import path traversal in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service and possible code execution

AnalysisAI

Path traversal via profile import in Wireshark lets a malicious configuration profile archive write files outside the intended profile directory, causing denial of service and potentially arbitrary code execution when a user imports it. Affected builds are Wireshark 4.6.0-4.6.4 and 4.4.0-4.4.14, with the flaw triggered by user interaction (importing a crafted profile) rather than network traffic. EPSS is very low (0.01%) and there is no public exploit identified at time of analysis; a vendor patch is available.

Technical ContextAI

Wireshark stores user-customizable configuration profiles (display filters, coloring rules, preferences, etc.) that can be exported and imported as archives. The vulnerability is a CWE-22 path traversal in the profile import routine: filenames inside the imported profile archive are not properly sanitized, so entries containing directory-traversal sequences (e.g. '../') can escape the destination profile folder and be written to arbitrary filesystem locations relative to the user running Wireshark. The single CPE cpe:2.3:a:wireshark_foundation:wireshark identifies the affected component as the Wireshark application itself (the GUI/profile subsystem) rather than a dissector or capture engine, distinguishing this from the packet-parsing bugs Wireshark more commonly fixes.

RemediationAI

Upgrade to a fixed Wireshark release per vendor advisory wnpa-sec-2026-21 (https://www.wireshark.org/security/wnpa-sec-2026-21.html): apply the patched maintenance build above the affected ranges (4.6.5 or later on the 4.6.x branch, and 4.4.15 or later on the 4.4.x branch - confirm exact build numbers against the advisory before deployment). Red Hat users should apply errata RHSA-2026:20600 / RHSA-2026:26182 (https://access.redhat.com/security/cve/CVE-2026-5656). As a compensating control until patched, do not import Wireshark configuration profiles from untrusted or unverified sources, and treat profile archives like any other untrusted file; organizations can also restrict or disable the profile-import workflow in managed deployments and run Wireshark as an unprivileged user to limit where a traversal write can land - the trade-off is loss of profile-sharing convenience but no loss of capture functionality.
