This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.","published":"2018-03-26T15:29:00.000Z","lastModified":"2026-06-17T01:50:57.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.0","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-119"],"affected":["apache/http server","debian/debian linux","canonical/ubuntu linux","netapp/santricity cloud connector","netapp/storage automation store","netapp/storagegrid","netapp/clustered data ontap","redhat/enterprise linux"],"epss":{"score":0.14991,"percentile":0.96699,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 15.0%, higher than 97% of all known CVEs.
