An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34812 in the wild and no public exploit code.\n\nAffected product: Synology Calendar. 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-2021-34812/ (Markdown: https://insights.sbomify.com/CVE-2021-34812/index.md)","id":"CVE-2021-34812","markdown":"https://insights.sbomify.com/CVE-2021-34812/index.md","name":"CVE-2021-34812","record":{"aliases":["GHSA-w3f5-2mqc-5c62"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Calendar","requires_auth":"none","summary":"Remote attackers can obtain sensitive information due to hard-coded credentials in Synology Calendar, requiring an upgrade to secure the system.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"calendar","vendor":"synology"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"Use of hard-coded credentials vulnerability in php component in Synology Calendar before 2.4.0-0761 allows remote attackers to obtain sensitive information via unspecified vectors.","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":"Hardcoded credentials in Synology Calendar","id":"CVE-2021-34812","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-34813"},"packages":[],"prev":{"headline":"Server-side request forgery in Download Station","id":"CVE-2021-34811"},"products":["Synology Calendar"],"published":"2021-06-18","related":[{"cvss_score":7.3,"headline":"Command injection in Calendar","id":"CVE-2019-11829","kev_date_added":null,"published":"2019-06-30"},{"cvss_score":6.5,"headline":"Cross-site request forgery in Synology Calendar","id":"CVE-2022-22686","kev_date_added":null,"published":"2022-07-26"},{"cvss_score":6.5,"headline":"Cross-site scripting in Synology Calendar","id":"CVE-2022-22682","kev_date_added":null,"published":"2022-07-12"},{"cvss_score":6.5,"headline":"Cross-site scripting in Calendar","id":"CVE-2019-11825","kev_date_added":null,"published":"2019-06-30"},{"cvss_score":6.5,"headline":"Cross-site scripting in Calendar","id":"CVE-2018-8915","kev_date_added":null,"published":"2018-05-10"},{"cvss_score":6.5,"headline":"Missing authorization in Synology Calendar","id":"CVE-2017-15891","kev_date_added":null,"published":"2017-12-08"}],"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":"2024-09-17","vendors":["Synology"]},"summary":"Remote attackers can obtain sensitive information due to hard-coded credentials in Synology Calendar, requiring an upgrade to secure the system.","url":"https://insights.sbomify.com/CVE-2021-34812/"}
