This comes from the \"HTTP_SESSION\" variable name used by mod_session to forward its data to CGIs, since the prefix \"HTTP_\" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N","score":5.3},"cwes":[],"references":["http://www.openwall.com/lists/oss-security/2018/03/24/4","http://www.securityfocus.com/bid/103520","http://www.securitytracker.com/id/1040568","https://access.redhat.com/errata/RHSA-2018:3558","https://access.redhat.com/errata/RHSA-2019:0366"],"products":["apache:http_server","canonical:ubuntu_linux","debian:debian_linux","netapp:clustered_data_ontap","netapp:santricity_cloud_connector","netapp:storage_automation_store","netapp:storagegrid","redhat:enterprise_linux"],"source":"nvd","synced_at":"2026-10-19T20:49:59.483420567+00:00"},"epss":{"cve":"CVE-2018-1283","score":0.09737,"percentile":0.95521,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
