{"id":"CVE-2023-48031","details":"OpenSupports v4.11.0 is vulnerable to Unrestricted Upload of File with Dangerous Type. In the comment function, an attacker can bypass security restrictions and upload a .bat file by manipulating the file's magic bytes to masquerade as an allowed type. This can enable the attacker to execute arbitrary code or establish a reverse shell, leading to unauthorized file writes or control over the victim's station via a crafted file upload operation.","modified":"2026-07-15T01:49:20.564896831Z","published":"2023-11-17T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/48xxx/CVE-2023-48031.json"},"references":[{"type":"WEB","url":"https://bugplorer.github.io/cve-opensupports/"},{"type":"WEB","url":"https://nitipoom-jar.github.io/CVE-2023-48031/"},{"type":"WEB","url":"https://nitipoom-jaroonchaipipat.github.io/security-research-portal/2023-48031"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/48xxx/CVE-2023-48031.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-48031"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensupports/opensupports","events":[{"introduced":"8b4b73402e3da962dd000a19aec490a2445c0ad3"},{"last_affected":"8b4b73402e3da962dd000a19aec490a2445c0ad3"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:opensupports:opensupports:4.11.0:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.11.0"},{"last_affected":"4.11.0"}]}}],"versions":["4.11.0","v4.11.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-48031.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
