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-2021-28095 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-28095/ (Markdown: https://insights.sbomify.com/CVE-2021-28095/index.md)","id":"CVE-2021-28095","markdown":"https://insights.sbomify.com/CVE-2021-28095/index.md","name":"CVE-2021-28095","record":{"aliases":["GHSA-jjv6-934h-3qjm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OX Documents","requires_auth":"none","summary":"Attackers can bypass access controls on XML documents in OX Documents due to weak CRC32 hashing, allowing unauthorized access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open-xchange_documents","vendor":"open-xchange"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-326","name":"Inadequate Encryption Strength"}],"description":"OX Documents before 7.10.5-rev5 has Incorrect Access Control for documents that contain XML structures because hash collisions can occur, due to use of CRC32.","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":"Weak cryptography in n/a","id":"CVE-2021-28095","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-28096"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2021-28094"},"products":["n/a"],"published":"2021-07-27","related":[{"cvss_score":6.5,"headline":"Weak cryptography in n/a","id":"CVE-2021-28093","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":6.5,"headline":"Weak cryptography in n/a","id":"CVE-2021-28094","kev_date_added":null,"published":"2021-07-27"}],"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":["n/a"]},"summary":"Attackers can bypass access controls on XML documents in OX Documents due to weak CRC32 hashing, allowing unauthorized access.","url":"https://insights.sbomify.com/CVE-2021-28095/"}
