Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-16790 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- symfony/form (Packagist): affected from 2.7.0; fixed in 2.7.38\n- symfony/form (Packagist): affected from 2.7.0; fixed in 2.7.38\n- symfony/form (Packagist): affected from 2.8.0; fixed in 2.8.31\n- symfony/form (Packagist): affected from 2.8.0; fixed in 2.8.31\n- symfony/form (Packagist): affected from 3.0.0; fixed in 3.2.14\n- symfony/form (Packagist): affected from 3.0.0; fixed in 3.2.14\n- symfony/form (Packagist): affected from 3.3.0; fixed in 3.3.13\n- symfony/form (Packagist): affected from 3.3.0; fixed in 3.3.13\n- symfony/symfony (Packagist): affected from 2.7.0; fixed in 2.7.38\n- symfony/symfony (Packagist): affected from 2.7.0; fixed in 2.7.38\n- symfony/symfony (Packagist): affected from 2.8.0; fixed in 2.8.31\n- symfony/symfony (Packagist): affected from 2.8.0; fixed in 2.8.31\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-2017-16790/ (Markdown: https://insights.sbomify.com/CVE-2017-16790/index.md)","id":"CVE-2017-16790","markdown":"https://insights.sbomify.com/CVE-2017-16790/index.md","name":"CVE-2017-16790","record":{"aliases":["DEBIAN-CVE-2017-16790","GHSA-cqqh-94r6-wjrg","UBUNTU-CVE-2017-16790"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Symfony Form component","requires_auth":"low_privilege","summary":"Attackers can read arbitrary server files by submitting crafted POST data to Symfony form FileType fields, exposing sensitive information.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"symfony","vendor":"sensiolabs"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An issue was discovered in Symfony before 2.7.38, 2.8.31, 3.2.14, 3.3.13, 3.4-BETA5, and 4.0-BETA5. When a form is submitted by the user, the request handler classes of the Form component merge POST data and uploaded files data into one array. This big array forms the data that are then bound to the form. At this stage there is no difference anymore between submitted POST data and uploaded files. A user can send a crafted HTTP request where the value of a \"FileType\" is sent as normal POST data that could be interpreted as a local file path on the server-side (for example, \"file:///etc/passwd\"). If the application did not perform any additional checks about the value submitted to the \"FileType\", the contents of the given file on the server could have been exposed to the attacker.","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
