Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-13893 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-13893/ (Markdown: https://insights.sbomify.com/CVE-2020-13893/index.md)","id":"CVE-2020-13893","markdown":"https://insights.sbomify.com/CVE-2020-13893/index.md","name":"CVE-2020-13893","record":{"aliases":["GHSA-m76c-23w7-gcrm"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Sage EasyPay","requires_auth":"low_privilege","summary":"Authenticated attackers can inject arbitrary web script or HTML via Unicode transformations in Sage EasyPay, 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":"easypay","vendor":"sage"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Multiple stored cross-site scripting (XSS) vulnerabilities in Sage EasyPay 10.7.5.10 allow authenticated attackers to inject arbitrary web script or HTML via multiple parameters through Unicode Transformations (Best-fit Mapping), as demonstrated by the full-width variants of the less-than sign (%EF%BC%9C) and greater-than sign (%EF%BC%9E).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2020-13893","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-13894"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-13892"},"products":["n/a"],"published":"2020-10-18","related":[],"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":"Authenticated attackers can inject arbitrary web script or HTML via Unicode transformations in Sage EasyPay, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2020-13893/"}
