A race condition flaw was found in the response headers Elasticsearch versions before 7.2.1 and 6.8.2 returns to a request.
Noroxi assessment
Priority: Monitor (action score 23/100)
- 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: 1% (FIRST EPSS); higher than 62.5% 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. Special conditions such as timing or configuration are required.
- Fixed version: org.elasticsearch:elasticsearch (Maven) 7.2.1, 6.8.2.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to org.elasticsearch:elasticsearch (Maven) 7.2.1, 6.8.2 or later.
