CVE-2026-5656 Details
Description
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
A path traversal vulnerability has been identified in Wireshark versions 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14. This vulnerability arises in the Configuration Profile import feature, where the application fails to properly validate file paths in ZIP archives in the extraction process. As a result, a crafted ZIP file can overwrite files in arbitrary locations, potentially leading to code execution. On POSIX systems, this could involve placing a malicious Lua plugin in a directory that Wireshark loads at startup, executing the code when Wireshark is launched.
Users should upgrade to Wireshark versions 4.6.5, 4.4.15 or later.
