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-2020-16255 in the wild and no public exploit code.\n\nAffected product: Owncloud Owncloud. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-16255/ (Markdown: https://insights.sbomify.com/CVE-2020-16255/index.md)","id":"CVE-2020-16255","markdown":"https://insights.sbomify.com/CVE-2020-16255/index.md","name":"CVE-2020-16255","record":{"aliases":["ALPINE-CVE-2020-16255","GHSA-686m-27qq-c25w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"ownCloud Core","requires_auth":"none","summary":"Cross-site scripting in the ownCloud login page allows attackers to inject scripts, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"owncloud","vendor":"owncloud"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"ownCloud (Core) before 10.5 allows XSS in login page 'forgot password.'","ecosystems":[],"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 in n/a","id":"CVE-2020-16255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"owncloud:owncloud","products":["owncloud:owncloud"],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"The API on Winston 1.5.4 devices is vulnerable to CSRF.","id":"CVE-2020-16256"},"packages":[],"prev":{"headline":"CSS Injection in Chartkick gem","id":"CVE-2020-16254"},"products":["n/a"],"published":"2021-01-15","related":[{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2021-35946","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2014-2052","kev_date_added":null,"published":"2020-02-11"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2014-2048","kev_date_added":null,"published":"2018-03-26"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2020-28645","kev_date_added":null,"published":"2021-02-09"},{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2015-4718","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2015-7698","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":8.5,"headline":"Information disclosure in n/a","id":"CVE-2016-1499","kev_date_added":null,"published":"2016-01-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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 the ownCloud login page allows attackers to inject scripts, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2020-16255/"}
