{"schemaVersion":3,"id":"CVE-2019-10743","aliases":["GHSA-h74j-692g-48mq"],"status":"published","duplicateOf":null,"title":null,"description":"All versions of archiver allow attacker to perform a Zip Slip attack via the \"unarchive\" functions. It is exploited using a specially crafted zip archive, that holds path traversal filenames. When exploited, a filename in a malicious archive is concatenated to the target extraction directory, which results in the final path ending up outside of the target folder. For instance, a zip may hold a file with a \"../../file.exe\" location and thus break out of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.","dates":{"published":"2019-10-28T22:09:22.000Z","modified":"2024-08-04T22:32:01.212Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.8,"severity":"medium","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:P","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.5,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":5.8,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:P","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
