An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-34427 exists.\n\nAffected product: The Eclipse Foundation Eclipse BIRT. 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-2021-34427/ (Markdown: https://insights.sbomify.com/CVE-2021-34427/index.md)","id":"CVE-2021-34427","markdown":"https://insights.sbomify.com/CVE-2021-34427/index.md","name":"CVE-2021-34427","record":{"aliases":["GHSA-c7m8-c6v2-pxw4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Eclipse BIRT reporting","requires_auth":"none","summary":"Attackers can upload malicious JSP files via query parameters in Eclipse BIRT, leading to remote code execution on the server.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"business_intelligence_and_reporting_tools","vendor":"eclipse"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Eclipse BIRT versions 4.8.0 and earlier, an attacker can use query parameters to create a JSP file which is accessible from remote (current BIRT viewer dir) to inject JSP code into the running instance.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-17","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-06-17T23:48:19Z","kind":"github_poc","ref":"https://github.com/rt1252/CVE-2021-34427","stars":0,"title":"Windows POC for CVE-2021-34427 affecting Birt Viewer"},{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-34427.yaml","stars":null,"title":"Eclipse BIRT Viewer - Remote Code Execution"}],"tier":"weaponised"},"has_fix":false,"headline":"File upload in Eclipse BIRT","id":"CVE-2021-34427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"SessionListener can prevent a session from being invalidated breaking logout","id":"CVE-2021-34428"},"packages":[],"prev":{"headline":"Arbitrary command execution in Keybase Client for Windows","id":"CVE-2021-34426"},"products":["Eclipse BIRT"],"published":"2021-06-25","related":[{"cvss_score":8.8,"headline":"Improper Input Validation In Eclipse BIRT","id":"CVE-2023-0100","kev_date_added":null,"published":"2023-03-15"},{"cvss_score":6.1,"headline":"Cross-site scripting in Eclipse BIRT","id":"CVE-2019-11776","kev_date_added":null,"published":"2019-08-09"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["The Eclipse Foundation"]},"summary":"Attackers can upload malicious JSP files via query parameters in Eclipse BIRT, leading to remote code execution on the server.","url":"https://insights.sbomify.com/CVE-2021-34427/"}
