Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-35774 exists.\n\nAffected packages and fixed versions:\n- com.twitter:twitter-server_2.12 (Maven): affected all versions; fixed in 20.12.0\n- com.twitter:twitter-server_2.12 (Maven): affected all versions; fixed in 20.12.0\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-2020-35774/ (Markdown: https://insights.sbomify.com/CVE-2020-35774/index.md)","id":"CVE-2020-35774","markdown":"https://insights.sbomify.com/CVE-2020-35774/index.md","name":"CVE-2020-35774","record":{"aliases":["GHSA-3mqv-8gxg-pfm4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"TwitterServer library","requires_auth":"low_privilege","summary":"Cross-site scripting vulnerability in TwitterServer allows attackers to inject scripts via the histograms endpoint in specific configurations.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"twitter-server","vendor":"twitter"}],"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":"server/handler/HistogramQueryHandler.scala in Twitter TwitterServer (aka twitter-server) before 20.12.0, in some configurations, allows XSS via the /histograms endpoint.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-35774.yaml","stars":null,"title":"twitter-server Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":true,"headline":"TwitterServer Cross-site Scripting via /histograms endpoint","id":"CVE-2020-35774","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":3,"next":{"headline":"Other in n/a","id":"CVE-2020-35775"},"packages":[{"ecosystem":"Maven","fixed":["20.12.0"],"introduced":["0"],"last_affected":[],"package":"com.twitter:twitter-server_2.12","purl":null,"source":"GHSA-3mqv-8gxg-pfm4"},{"ecosystem":"Maven","fixed":["20.12.0"],"introduced":["0"],"last_affected":[],"package":"com.twitter:twitter-server_2.12","purl":"pkg:maven/com.twitter/twitter-server_2.12","source":"GHSA-3mqv-8gxg-pfm4"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-35773"},"products":["n/a"],"published":"2020-12-29","related":[],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in TwitterServer allows attackers to inject scripts via the histograms endpoint in specific configurations.","url":"https://insights.sbomify.com/CVE-2020-35774/"}
