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-2021-44543 in the wild and no public exploit code.\n\nAffected product: privoxy. 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-2021-44543/ (Markdown: https://insights.sbomify.com/CVE-2021-44543/index.md)","id":"CVE-2021-44543","markdown":"https://insights.sbomify.com/CVE-2021-44543/index.md","name":"CVE-2021-44543","record":{"aliases":["ALPINE-CVE-2021-44543","DEBIAN-CVE-2021-44543","GHSA-hf3j-m5fx-q82c","UBUNTU-CVE-2021-44543"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Privoxy web proxy","requires_auth":"none","summary":"An XSS vulnerability in Privoxy allows attackers to execute scripts when the user-manual is served, requiring specific configuration.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"privoxy","vendor":"privoxy"}],"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":"An XSS vulnerability was found in Privoxy which was fixed in cgi_error_no_template() by encode the template name when Privoxy is configured to servce the user-manual itself.","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 privoxy","id":"CVE-2021-44543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Delta Electronics DIAEnergie (Update A)","id":"CVE-2021-44544"},"packages":[],"prev":{"headline":"Denial of service in Privoxy","id":"CVE-2021-44542"},"products":["privoxy"],"published":"2021-12-23","related":[{"cvss_score":7.7,"headline":"Local privilege escalation from user privoxy to root","id":"CVE-2019-3699","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":7.5,"headline":"Denial of service in Privoxy","id":"CVE-2021-44540","kev_date_added":null,"published":"2021-12-23"},{"cvss_score":7.5,"headline":"Denial of service in Privoxy","id":"CVE-2021-44541","kev_date_added":null,"published":"2021-12-23"},{"cvss_score":7.5,"headline":"Denial of service in Privoxy","id":"CVE-2021-44542","kev_date_added":null,"published":"2021-12-23"},{"cvss_score":7.5,"headline":"Denial of service in privoxy","id":"CVE-2021-20209","kev_date_added":null,"published":"2021-05-25"},{"cvss_score":7.5,"headline":"Denial of service in privoxy","id":"CVE-2020-35502","kev_date_added":null,"published":"2021-03-25"},{"cvss_score":7.5,"headline":"Denial of service in privoxy","id":"CVE-2021-20210","kev_date_added":null,"published":"2021-03-25"}],"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":"An XSS vulnerability in Privoxy allows attackers to execute scripts when the user-manual is served, requiring specific configuration.","url":"https://insights.sbomify.com/CVE-2021-44543/"}
