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-2021-22656 in the wild and no public exploit code.\n\nAffected product: Advantech iView. 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-2021-22656/ (Markdown: https://insights.sbomify.com/CVE-2021-22656/index.md)","id":"CVE-2021-22656","markdown":"https://insights.sbomify.com/CVE-2021-22656/index.md","name":"CVE-2021-22656","record":{"aliases":["GHSA-qrfm-956x-83hh"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Advantech iView","requires_auth":"none","summary":"An attacker can exploit a directory traversal vulnerability in Advantech iView to read sensitive files from the system.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"iview","vendor":"advantech"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Advantech iView versions prior to v5.7.03.6112 are vulnerable to directory traversal, which may allow an attacker to read sensitive files.","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":"Path traversal in Advantech iView","id":"CVE-2021-22656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"mySCADA myPRO","id":"CVE-2021-22657"},"packages":[],"prev":{"headline":"Memory corruption in Tellus Lite V-Simulator and V-Server Lite","id":"CVE-2021-22655"},"products":["Advantech iView"],"published":"2021-02-11","related":[{"cvss_score":9.8,"headline":"Advantech iView","id":"CVE-2022-2143","kev_date_added":null,"published":"2022-07-22"},{"cvss_score":9.8,"headline":"Missing authorization in iView","id":"CVE-2021-32930","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.8,"headline":"Missing authorization in Advantech iView","id":"CVE-2021-22652","kev_date_added":null,"published":"2021-02-11"},{"cvss_score":9.8,"headline":"SQL injection in Advantech iView","id":"CVE-2021-22658","kev_date_added":null,"published":"2021-02-11"},{"cvss_score":9.8,"headline":"Path traversal in Advantech iView","id":"CVE-2020-16245","kev_date_added":null,"published":"2020-08-25"},{"cvss_score":9.8,"headline":"SQL injection in Advantech iView","id":"CVE-2020-14497","kev_date_added":null,"published":"2020-07-15"},{"cvss_score":9.8,"headline":"Auth bypass in Advantech iView","id":"CVE-2020-14501","kev_date_added":null,"published":"2020-07-15"}],"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 attacker can exploit a directory traversal vulnerability in Advantech iView to read sensitive files from the system.","url":"https://insights.sbomify.com/CVE-2021-22656/"}
