{"schema":"threatline.record/2","record":{"id":"CVE-2026-109430","aliases":[],"summary":"Ellucian WebAdvisor 3.2 Unauthenticated XXE Injection","details":"Ellucian WebAdvisor 3.2 contains an unauthenticated XML External Entity (XXE) injection vulnerability that allows remote attackers to submit crafted XML POST requests to the /WebAdvisor/WebAdvisor endpoint without disabling external entity and DTD resolution. Attackers can exploit this flaw to force the server into SSRF requests, coerce NTLMv2 hash disclosure via attacker-controlled SMB shares, and read arbitrary files from the underlying Windows host through an out-of-band error-based channel. WebAdvisor entered end-of-support status in June 2022 and users are encouraged to migrate to Colleague Self-Service.","categories":["Unclassified"],"product":"WebAdvisor","vendor":"Ellucian","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109430","source_modified_at":"2026-10-20T02:35:29.262Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"WebAdvisor","vendor":"Ellucian","versions":[{"status":"affected","version":"3.2","versionType":"custom"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00344,"percentile":0.26717,"score_date":"2026-10-23"},"published_at":"2026-10-15T01:31:06.896Z","modified_at":"2026-10-20T02:35:29.262Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109430","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T02:35:29.262Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109430","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.ellucian.com/","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/ellucian-webadvisor-unauthenticated-xxe-injection","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-20T02:35:20.853941Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T02:35:29.262Z","content_hash":"baf97c600c18538da5c8eafe436bc54680200441921b34d08c8b2d37e9b5fe1a"}}
