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-2017-18121 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- simplesamlphp/simplesamlphp (Packagist): affected from 1.12.0; fixed in 1.14.16\n- simplesamlphp/simplesamlphp (Packagist): affected from 1.12.0; fixed in 1.14.16\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-2017-18121/ (Markdown: https://insights.sbomify.com/CVE-2017-18121/index.md)","id":"CVE-2017-18121","markdown":"https://insights.sbomify.com/CVE-2017-18121/index.md","name":"CVE-2017-18121","record":{"aliases":["DEBIAN-CVE-2017-18121","GHSA-fv7m-wc3v-wr3w","UBUNTU-CVE-2017-18121"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SimpleSAMLphp consentAdmin","requires_auth":"none","summary":"An attacker can execute arbitrary JavaScript in a victim's browser via crafted links in the SimpleSAMLphp consentAdmin module.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"simplesamlphp","vendor":"simplesamlphp"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The consentAdmin module in SimpleSAMLphp through 1.14.15 is vulnerable to a Cross-Site Scripting attack, allowing an attacker to craft links that could execute arbitrary JavaScript code on the victim's web browser.","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":"SimpleSAMLphp XSS Vulnerability","id":"CVE-2017-18121","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"xss","year":"2017"},"n_packages":2,"n_references":3,"next":{"headline":"SimpleSAMLphp Signature validation bypass","id":"CVE-2017-18122"},"packages":[{"ecosystem":"Packagist","fixed":["1.14.16"],"introduced":["1.12.0"],"last_affected":[],"package":"simplesamlphp/simplesamlphp","purl":null,"source":"GHSA-fv7m-wc3v-wr3w"},{"ecosystem":"Packagist","fixed":["1.14.16"],"introduced":["1.12.0"],"last_affected":[],"package":"simplesamlphp/simplesamlphp","purl":"pkg:composer/simplesamlphp/simplesamlphp","source":"GHSA-fv7m-wc3v-wr3w"}],"prev":{"headline":"Use after free in n/a","id":"CVE-2017-18120"},"products":["n/a"],"published":"2018-02-02","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"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":"An attacker can execute arbitrary JavaScript in a victim's browser via crafted links in the SimpleSAMLphp consentAdmin module.","url":"https://insights.sbomify.com/CVE-2017-18121/"}
