{"id":"CVE-2023-32676","summary":"Autolab tar slip in Install Assessment functionality (`GHSL-2023-081`)","details":"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.","aliases":["GHSA-x9hj-r9q4-832c"],"modified":"2026-08-12T03:51:44.048778643Z","published":"2023-05-26T22:44:09.157Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/32xxx/CVE-2023-32676.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/32xxx/CVE-2023-32676.json"},{"type":"ADVISORY","url":"https://github.com/autolab/Autolab/security/advisories/GHSA-x9hj-r9q4-832c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-32676"},{"type":"ADVISORY","url":"https://securitylab.github.com/advisories/GHSL-2023-081_GHSL-2023-082_Autolab/"},{"type":"FIX","url":"https://github.com/autolab/Autolab/commit/14f508484a8323eceb0cf3a128573b43eabbc80d"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/autolab/autolab","events":[{"introduced":"0"},{"fixed":"03d3a54e62f49cef64e5eed7aa34bfeec18db0bd"},{"fixed":"14f508484a8323eceb0cf3a128573b43eabbc80d"}],"database_specific":{"cpe":"cpe:2.3:a:autolabproject:autolab:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.11.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v2.10.0","v2.9.0","v2.8.0","v2.7.0","v2.6.0","v2.4.0","v2.3.0","v2.2.1","2.2.1","2.2.0","v2.2.0","v2.0.8","2.1.0","2.0.8","v2.0.7","v2.0.6","v2.0.5","2.0.4","v2.0.3","v2.0.2","v1.7.0","v1.6.0","v1.5.1","v1.5.0","v1.4.1","v1.4.0","v1.3.0","v1.2.0","v1.1.1","v1.1.0","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-32676.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:H"}]}
