Because adminer/include/auth.inc.php invokes Driver::connect() before the login result is validated, an unauthenticated attacker who submits crafted auth[server], auth[username], and auth[password] parameters can cause the Adminer server to issue an HTTP GET request (via get_url()/file_get_contents()) to an arbitrary reachable host and port. The driver validates only general server syntax and does not block loopback, private, link-local, or other reserved addresses; if no port is given it appends the default 9200, and Adminer's generic port check rejects ports below 1024. Selected JSON error fields from non-2xx Elasticsearch-style responses, as well as connection failures, are rendered on the login page, providing a port-scanning oracle and enabling internal network reconnaissance and service fingerprinting. Exploitation requires that the optional Elasticsearch driver be explicitly deployed (e.g., via the adminer/elastic.php template or an adminer_object() configuration; it is not loaded in a default build) and that PHP allow_url_fopen be enabled."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "Server-Side Request Forgery (SSRF)", "cweId": "CWE-918", "type": "CWE"}]}], "affected": [{"vendor": "vrana", "product": "adminer", "defaultStatus": "unaffected", "versions": [{"version": "0", "status": "affected", "versionType": "semver", "lessThan": "6.0.2"}, {"version": "6.0.2", "status": "unaffected", "versionType": "semver"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:adminer:adminer:*:*:*:*:*:*:*:*", "versionEndExcluding": "6.0.2"}]}]}], "metrics": [{"format": "CVSS", "cvssV4_0": {"version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N", "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "LOW", "vulnIntegrityImpact": "NONE", "vulnAvailabilityImpact": "NONE", "subConfidentialityImpact": "LOW", "subIntegrityImpact": "NONE", "subAvailabilityImpact": "NONE", "baseScore": 6.9, "baseSeverity": "MEDIUM"}}, {"format": "CVSS", "cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "NONE", "availabilityImpact": "NONE", "baseScore": 5.8, "baseSeverity": "MEDIUM"}}], "references": [{"url": "https://github.com/vrana/adminer/security/advisories/GHSA-q8h3-4cx4-prgm", "tags": ["vendor-advisory"], "name": "GitHub Security Advisory (GHSA-q8h3-4cx4-prgm)"}, {"name": "VulnCheck Advisory: Adminer before 6.0.2 Unauthenticated SSRF via Elasticsearch Driver", "tags": ["third-party-advisory"], "url": "https://www.vulncheck.com/advisories/adminer-before-6.0.2-unauthenticated-ssrf-via-elasticsearch-driver"}], "credits": [{"lang": "en", "value": "lichoin", "type": "reporter"}], "x_generator": {"engine": "vulncheck-endgame"}}}}
