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-2021-33591 in the wild and no public exploit code.\n\nAffected product: Naver Comic Viewer. 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-2021-33591/ (Markdown: https://insights.sbomify.com/CVE-2021-33591/index.md)","id":"CVE-2021-33591","markdown":"https://insights.sbomify.com/CVE-2021-33591/index.md","name":"CVE-2021-33591","record":{"aliases":["GHSA-hxmq-jv8j-gm7q"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Naver Comic Viewer","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a crafted HTML page due to an exposed remote debugging port in Naver Comic Viewer.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"naver","cpe":[{"product":"comic_viewer","vendor":"naver"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-489","name":"Active Debug Code"}],"description":"An exposed remote debugging port in Naver Comic Viewer prior to 1.0.15.0 allowed a remote attacker to execute arbitrary code via a crafted HTML page.","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":"Code injection in Naver Comic Viewer","id":"CVE-2021-33591","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in NAVER Toolbar","id":"CVE-2021-33592"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-33590"},"products":["Naver Comic Viewer"],"published":"2021-05-28","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":"2024-08-03","vendors":["NAVER"]},"summary":"Remote attackers can execute arbitrary code via a crafted HTML page due to an exposed remote debugging port in Naver Comic Viewer.","url":"https://insights.sbomify.com/CVE-2021-33591/"}
