High (7.0) in eclipse foundation eclipse kura. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.
On this page
In Kura versions <= 5.6.2, the "Command" file-upload handler at `POST /admin/denali/file/command` extracts a client-supplied ZIP archive into the configured `command.working.directory`. The path-containment check `validateFileName()` compares canonical paths with `String.startsWith()` without appending a trailing path separator, so an entry that canonicalises to a sibling directory sharing the same string prefix (e.g. `/tmpevil/x` when the intended directory is `/tmp`) is accepted. The handler then calls `parent.mkdirs()` and `new FileOutputStream(newFile)`, creating directories and writing attacker-controlled bytes outside the intended extraction root.
The command service is disabled by default since Kura 4.0.0 [1]. The issue does not apply when the command service is disabled. The caller must be authenticated with `rest.command` permission.

Explain CVE-2026-111729 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-111729?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-111729?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-111729 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
