An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-2049 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-2049/ (Markdown: https://insights.sbomify.com/CVE-2016-2049/index.md)","id":"CVE-2016-2049","markdown":"https://insights.sbomify.com/CVE-2016-2049/index.md","name":"CVE-2016-2049","record":{"aliases":["GHSA-w7j5-jxx6-p7j4","UBUNTU-CVE-2016-2049"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP OpenID library","requires_auth":"none","summary":"Attackers can hijack user authentication in the JanRain PHP OpenID library by spoofing the HTTP Host header to bypass realm checks.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"php-openid","vendor":"janrain"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"examples/consumer/common.php in JanRain PHP OpenID library (aka php-openid) improperly checks the openid.realm parameter against the SERVER_NAME element in the SERVER superglobal array, which might allow remote attackers to hijack the authentication of arbitrary users via vectors involving a crafted HTTP Host header.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Auth bypass in n/a","id":"CVE-2016-2049","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-2050"},"packages":[],"prev":{"headline":"Django Access Restrictions Bypass","id":"CVE-2016-2048"},"products":["n/a"],"published":"2016-02-01","related":[{"cvss_score":7.5,"headline":"PHP OpenID Library Denial of Service vulnerability","id":"CVE-2013-4701","kev_date_added":null,"published":"2013-08-21"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-2011-3707","kev_date_added":null,"published":"2011-09-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can hijack user authentication in the JanRain PHP OpenID library by spoofing the HTTP Host header to bypass realm checks.","url":"https://insights.sbomify.com/CVE-2016-2049/"}
