Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-14773 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- symfony/http-foundation (Packagist): affected from 2.7.0; fixed in 2.7.49\n- symfony/http-foundation (Packagist): affected from 2.7.0; fixed in 2.7.49\n- symfony/http-foundation (Packagist): affected from 2.8.0; fixed in 2.8.44\n- symfony/http-foundation (Packagist): affected from 2.8.0; fixed in 2.8.44\n- symfony/http-foundation (Packagist): affected from 3.0.0; fixed in 3.3.18\n- symfony/http-foundation (Packagist): affected from 3.0.0; fixed in 3.3.18\n- symfony/http-foundation (Packagist): affected from 3.4.0; fixed in 3.4.14\n- symfony/http-foundation (Packagist): affected from 3.4.0; fixed in 3.4.14\n- symfony/http-foundation (Packagist): affected from 4.0.0; fixed in 4.0.14\n- symfony/http-foundation (Packagist): affected from 4.0.0; fixed in 4.0.14\n- symfony/http-foundation (Packagist): affected from 4.1.0; fixed in 4.1.3\n- symfony/http-foundation (Packagist): affected from 4.1.0; fixed in 4.1.3\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-2018-14773/ (Markdown: https://insights.sbomify.com/CVE-2018-14773/index.md)","id":"CVE-2018-14773","markdown":"https://insights.sbomify.com/CVE-2018-14773/index.md","name":"CVE-2018-14773","record":{"aliases":["DEBIAN-CVE-2018-14773","GHSA-8wgj-6wx8-h5hq","UBUNTU-CVE-2018-14773"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Symfony HttpFoundation","requires_auth":"low_privilege","summary":"Attackers can bypass security controls or poison caches by spoofing request paths via legacy IIS headers in Symfony HttpFoundation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"drupal","vendor":"drupal"},{"product":"symfony","vendor":"sensiolabs"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"An issue was discovered in Http Foundation in Symfony 2.7.0 through 2.7.48, 2.8.0 through 2.8.43, 3.3.0 through 3.3.17, 3.4.0 through 3.4.13, 4.0.0 through 4.0.13, and 4.1.0 through 4.1.2. It arises from support for a (legacy) IIS header that lets users override the path in the request URL via the X-Original-URL or X-Rewrite-URL HTTP request header. These headers are designed for IIS support, but it's not verified that the server is in fact running IIS, which means anybody who can send these requests to an application can trigger this. This affects \\Symfony\\Component\\HttpFoundation\\Request::prepareRequestUri() where X-Original-URL and X_REWRITE_URL are both used. The fix drops support for these methods so that they cannot be used as attack vectors such as web cache poisoning.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Symfony
