CVE-2023-39196: Apache Ozone: Missing mutual TLS authentication in one of the service internal Ozone Storage Container Manager endpoints

Noroxi assessment

Priority: Monitor (action score 21/100)

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: 0.79% (FIRST EPSS); higher than 56.3% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: Apache Software Foundation Apache Ozone 1.4.0.

Low priority for now. Upgrade to Apache Software Foundation Apache Ozone 1.4.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper Authentication vulnerability in Apache Ozone. The vulnerability allows an attacker to download metadata internal to the Storage Container Manager service without proper authentication. The attacker is not allowed to do any modification within the Ozone Storage Container Manager service using this vulnerability. The accessible metadata does not contain sensitive information that can be used to exploit the system later on, and the accessible data does not make it possible to gain access to actual user data within Ozone. This issue affects Apache Ozone: 1.2.0 and subsequent releases up until 1.3.0. Users are recommended to upgrade to version 1.4.0, which fixes the issue.

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.
