Overview
Recently, NSFOCUS CERT detected that JumpServer issued a security announcement and fixed two remote code execution vulnerabilities. At present, the PoC of the vulnerability has been made public. Affected users should take protective measures as soon as possible.
CVE-2024-29201: Since the Ansible module in JumpServer does not perform complete input verification, attackers with low-privilege accounts can bypass the input verification mechanism to execute arbitrary code in the Celery container and steal sensitive information from the host or manipulate the database.
CVE-2024-29202: Authenticated attackers can execute arbitrary code in the Celery container by building a malicious playbook template using the Jinja2 template engine in Ansible, and steal sensitive information from the host or manipulate the database.
