{"id":"CVE-2023-32676","state":"PUBLISHED","title":"Autolab tar slip in Install Assessment functionality (`GHSL-2023-081`)","description":"Autolab is a course management service that enables auto-graded programming assignments. A Tar slip vulnerability was found in the Install assessment functionality of Autolab. To exploit this vulnerability an authenticated attacker with instructor permissions needs to upload a specially crafted Tar file. Using the install assessment functionality an attacker can feed a Tar file that contain files with paths pointing outside of the target directory (e.g.,  `../../../../tmp/tarslipped1.sh`). When the Install assessment form is submitted the files inside of the archives are expanded to the attacker-chosen locations. This issue has been addressed in version 2.11.0. Users are advised to upgrade.","publishedAt":"2023-05-26T22:44:09.157Z","updatedAt":"2024-10-15T16:29:34.601Z","severity":{"score":6.7,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["autolab Autolab"],"affected":[{"vendor":"autolab","product":"Autolab","versions":[{"version":"< 2.11.0","status":"affected"}]}],"references":["https://github.com/autolab/Autolab/security/advisories/GHSA-x9hj-r9q4-832c","https://github.com/autolab/Autolab/commit/14f508484a8323eceb0cf3a128573b43eabbc80d","https://securitylab.github.com/advisories/GHSL-2023-081_GHSL-2023-082_Autolab/"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:06:00.499Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/32xxx/CVE-2023-32676.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-32676","state":"PUBLISHED","datePublished":"2023-05-26T22:44:09.157Z","dateUpdated":"2024-10-15T16:29:34.601Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-05-11T16:33:45.731Z"},"containers":{"cna":{"title":"Autolab tar slip in Install Assessment functionality (`GHSL-2023-081`)","descriptions":[{"lang":"en","value":"Autolab is a course management service that enables auto-graded programming assignments.
