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-2021-28110 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-2021-28110/ (Markdown: https://insights.sbomify.com/CVE-2021-28110/index.md)","id":"CVE-2021-28110","markdown":"https://insights.sbomify.com/CVE-2021-28110/index.md","name":"CVE-2021-28110","record":{"aliases":["GHSA-w56w-4253-9ggg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Payment Gateway","requires_auth":"none","summary":"An XML External Entity vulnerability in the TranzWare e-Commerce Payment Gateway allows attackers to read sensitive files or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tranzware_e-commerce_payment_gateway","vendor":"compassplus"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"/exec in TranzWare e-Commerce Payment Gateway (TWEC PG) before 3.1.27.5 had a vulnerability in its XML parser.","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":"XML external entity in n/a","id":"CVE-2021-28110","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2021-28111"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-28109"},"products":["n/a"],"published":"2021-03-19","related":[{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2021-28126","kev_date_added":null,"published":"2021-03-19"}],"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":"An XML External Entity vulnerability in the TranzWare e-Commerce Payment Gateway allows attackers to read sensitive files or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-28110/"}
