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-2024-21499 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/greenpau/caddy-security (Go): affected all versions; no fix listed\n- github.com/greenpau/caddy-security (Go): affected all versions up to 1.1.23; no fix listed\n- github.com/greenpau/caddy-security (Go): affected all versions up to 1.1.23; no fix listed\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-2024-21499/ (Markdown: https://insights.sbomify.com/CVE-2024-21499/index.md)","id":"CVE-2024-21499","markdown":"https://insights.sbomify.com/CVE-2024-21499/index.md","name":"CVE-2024-21499","record":{"aliases":["GHSA-r969-783f-6jqr","GO-2024-2562"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Caddy security plugin","requires_auth":"none","summary":"Attackers can bypass security mechanisms or cause TLS confusion by injecting the X-Forwarded-Proto header in Caddy security plugin.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"caddy-security","vendor":"greenpau"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:P","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"},{"id":"CWE-644","name":"Improper Neutralization of HTTP Headers for Scripting Syntax"}],"description":"All versions of the package github.com/greenpau/caddy-security are vulnerable to HTTP Header Injection via the X-Forwarded-Proto header due to redirecting to the injected protocol.Exploiting this vulnerability could lead to bypass of security mechanisms or confusion in handling TLS.","ecosystems":["Go"],"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":"Improper Neutralization of HTTP Headers in github.com/greenpau/caddy-security","id":"CVE-2024-21499","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"security_feature_bypass","year":"2024"},"n_packages":3,"n_references":3,"next":{"headline":"Improper Restriction of Excessive Authentication Attempts in github.com/greenpau/caddy-security","id":"CVE-2024-21500"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/greenpau/caddy-security","purl":"pkg:golang/github.com/greenpau/caddy-security","source":"GO-2024-2562"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["1.1.23"],"package":"github.com/greenpau/caddy-security","purl":null,"source":"GHSA-r969-783f-6jqr"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["1.1.23"],"package":"github.com/greenpau/caddy-security","purl":"pkg:golang/github.com/greenpau/caddy-security","source":"GHSA-r969-783f-6jqr"}],"prev":{"headline":"Server-Side Request Forgery in github.com/greenpau/caddy-security","id":"CVE-2024-21498"},"products":["github.com/greenpau/caddy-security"],"published":"2024-02-17","related":[{"cvss_score":6.5,"headline":"Use of Insufficiently Random Values in github.com/greenpau/caddy-security","id":"CVE-2024-21495","kev_date_added":null,"published":"2024-02-17"},{"cvss_score":5.4,"headline":"Authentication Bypass by Spoofing in github.com/greenpau/caddy-security","id":"CVE-2024-21494","kev_date_added":null,"published":"2024-02-17"},{"cvss_score":5.4,"headline":"Open Redirect in github.com/greenpau/caddy-security","id":"CVE-2024-21497","kev_date_added":null,"published":"2024-02-17"},{"cvss_score":5.3,"headline":"Improper Validation of Array Index in github.com/greenpau/caddy-security","id":"CVE-2024-21493","kev_date_added":null,"published":"2024-02-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Attackers can bypass security mechanisms or cause TLS confusion by injecting the X-Forwarded-Proto header in Caddy security plugin.","url":"https://insights.sbomify.com/CVE-2024-21499/"}
