{"id":"CVE-2023-32317","state":"PUBLISHED","title":"Autolab tar slip in cheat checker functionality (`GHSL-2023-082`)","description":"Autolab is a course management service that enables auto-graded programming assignments. A Tar slip vulnerability was found in the MOSS cheat checker functionality of Autolab. To exploit this vulnerability an authenticated attacker with instructor permissions needs to upload a specially crafted Tar file. Both \"Base File Tar\" and \"Additional file archive\" can be fed with Tar files that contain paths outside their target directories (e.g.,  `../../../../tmp/tarslipped2.sh`). When the MOSS cheat checker is started the files inside of the archives are expanded to the attacker-chosen locations. This issue may lead to arbitrary file write within the scope of the running process.  This issue has been addressed in version 2.11.0. Users are advised to upgrade.","publishedAt":"2023-05-26T22:42:09.929Z","updatedAt":"2024-08-02T15:10:24.879Z","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-h8g5-vhm4-wx6g","https://github.com/autolab/Autolab/commit/410a9228ee265f80692334d75eb2c3b4dac6f9e5","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-2023-32317.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-32317","state":"PUBLISHED","datePublished":"2023-05-26T22:42:09.929Z","dateUpdated":"2024-08-02T15:10:24.879Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-05-08T13:26:03.879Z"},"containers":{"cna":{"title":"Autolab tar slip in cheat checker functionality (`GHSL-2023-082`)","descriptions":[{"lang":"en","value":"Autolab is a course management service that enables auto-graded programming assignments.
