Prior to 4.08.010, efw.file.FileManager.unZip writes zip entries to disk using new File(baseDir, zipEntry.getName()) with no canonical-path check. An entry name such as ../../../pwned.jsp escapes the intended extraction directory and lands anywhere the Tomcat process can write — including the servlet context root. Combined with the framework's multipart /uploadServlet and an event that calls file.saveUploadFiles + FileManager.unZip, a remote attacker with no credentials drops a JSP webshell and executes arbitrary commands as the Tomcat user. This vulnerability is fixed in 4.08.010." } ], "source": { "advisory": "GHSA-q7jx-7x5r-r9f6", "discovery": "UNKNOWN" } }, "adp": [ { "references": [ { "url": "https://github.com/efwGrp/efw4.X/security/advisories/GHSA-q7jx-7x5r-r9f6", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-05-18T14:56:21.975090Z", "id": "CVE-2026-44257", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-05-18T14:57:04.080Z" } } ] } }
