CVE-2023-43651: Remote code execution on the host system via MongoDB shell in jumpserver

CriticalCVSS 9.9 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 40/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.1% (FIRST EPSS); higher than 81.9% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: github.com/jumpserver/koko (Go) 2.28.20, 3.7.1.

Add it to your regular patch cycle. Upgrade to github.com/jumpserver/koko (Go) 2.28.20, 3.7.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

JumpServer is an open source bastion host. An authenticated user can exploit a vulnerability in MongoDB sessions to execute arbitrary commands, leading to remote code execution. This vulnerability may further be leveraged to gain root privileges on the system. Through the WEB CLI interface provided by the koko component, a user logs into the authorized mongoDB database and exploits the MongoDB session to execute arbitrary commands. This vulnerability has been addressed in versions 2.28.20 and 3.7.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
