CVE-2023-42819Public exploitNetwork attack vector

Arbitrary file read and write via path traversal

Published Sep 26, 2023 · Updated Sep 23, 2024

Path traversal in JumpServer 3.0.0 through 3.6.4 allows remote authenticated users to read or write arbitrary server files. The playbook file API passes attacker-controlled key, parent, and name values to os.path.join, allowing traversal outside the playbook work directory. A logged-in user must create or access a playbook and obtain its identifier; exploitation reaches files accessible to the JumpServer process.
