An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-17551 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- impresscms/impresscms (Packagist): affected all versions; fixed in 1.4.1\n- impresscms/impresscms (Packagist): affected all versions; fixed in 1.4.1\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-2020-17551/ (Markdown: https://insights.sbomify.com/CVE-2020-17551/index.md)","id":"CVE-2020-17551","markdown":"https://insights.sbomify.com/CVE-2020-17551/index.md","name":"CVE-2020-17551","record":{"aliases":["GHSA-j29g-g982-pwpv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ImpressCMS","requires_auth":"high_privilege","summary":"Cross-site scripting in ImpressCMS admin module allows attackers to execute arbitrary remote code.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"impresscms","vendor":"impresscms"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"ImpressCMS 1.4.0 is affected by XSS in modules/system/admin.php which may result in arbitrary remote code execution.","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":"Cross-site scripting (XSS)","id":"CVE-2020-17551","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-17563"},"packages":[{"ecosystem":"Packagist","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"impresscms/impresscms","purl":null,"source":"GHSA-j29g-g982-pwpv"},{"ecosystem":"Packagist","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"impresscms/impresscms","purl":"pkg:composer/impresscms/impresscms","source":"GHSA-j29g-g982-pwpv"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-17542"},"products":["n/a"],"published":"2020-10-07","related":[{"cvss_score":10,"headline":"Multiple unspecified vulnerabilities in ImpressCMS 1.0 have unknown impact and attack vectors, related to modules/admin.php and \"a few files","id":"CVE-2008-3453","kev_date_added":null,"published":"2008-08-04"},{"cvss_score":9.8,"headline":"SQL Injection in ImpressCMS","id":"CVE-2021-26599","kev_date_added":null,"published":"2022-03-28"},{"cvss_score":9.8,"headline":"Type Confusion in ImpressCMS","id":"CVE-2021-26600","kev_date_added":null,"published":"2022-03-28"},{"cvss_score":9.8,"headline":"Path Traversal in ImpressCMS","id":"CVE-2022-24977","kev_date_added":null,"published":"2022-02-13"},{"cvss_score":9.3,"headline":"ImpressCMS 1.4.4 - Unrestricted File Upload","id":"CVE-2022-50912","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":8.1,"headline":"Path Traversal in ImpressCMS","id":"CVE-2021-26601","kev_date_added":null,"published":"2022-03-28"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2010-4271","kev_date_added":null,"published":"2010-11-16"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Cross-site scripting in ImpressCMS admin module allows attackers to execute arbitrary remote code.","url":"https://insights.sbomify.com/CVE-2020-17551/"}
