Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3256 in the wild and no public exploit code.\n\nAffected product: Advantech  R-SeeNet. 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-2023-3256/ (Markdown: https://insights.sbomify.com/CVE-2023-3256/index.md)","id":"CVE-2023-3256","markdown":"https://insights.sbomify.com/CVE-2023-3256/index.md","name":"CVE-2023-3256","record":{"aliases":["GHSA-79pm-5425-72gv"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Advantech R-SeeNet","requires_auth":"low_privilege","summary":"Low-level users can access and load local file contents in Advantech R-SeeNet due to improper control of file names or paths.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"r-seenet","vendor":"advantech"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-610","name":"Externally Controlled Reference to a Resource in Another Sphere"},{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"Advantech R-SeeNet \nversions 2.4.22 \nallows low-level users to access and load the content of local 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":"Advantech R-SeeNet External Control of File Name or Path","id":"CVE-2023-3256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in iBoot PDU","id":"CVE-2023-3259"},"packages":[],"prev":{"headline":"Qemu: vnc: infinite loop in inflate_buffer() leads to denial of service","id":"CVE-2023-3255"},"products":["R-SeeNet"],"published":"2023-06-22","related":[{"cvss_score":9.8,"headline":"Advantech R-SeeNet Unauthenticated Read/Write","id":"CVE-2023-5642","kev_date_added":null,"published":"2023-10-18"},{"cvss_score":9.8,"headline":"Advantech R-SeeNet Use of Hard-coded Credentials","id":"CVE-2023-2611","kev_date_added":null,"published":"2023-06-22"},{"cvss_score":9.8,"headline":"Memory corruption in R-SeeNet","id":"CVE-2022-3385","kev_date_added":null,"published":"2022-10-27"},{"cvss_score":9.8,"headline":"Memory corruption in R-SeeNet","id":"CVE-2022-3386","kev_date_added":null,"published":"2022-10-27"},{"cvss_score":9.8,"headline":"Command injection in Advantech","id":"CVE-2021-21805","kev_date_added":null,"published":"2021-08-05"},{"cvss_score":9.6,"headline":"Cross-site scripting in Advantech","id":"CVE-2021-21799","kev_date_added":null,"published":"2021-07-16"},{"cvss_score":9.6,"headline":"Cross-site scripting in Advantech","id":"CVE-2021-21800","kev_date_added":null,"published":"2021-07-16"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-01-16","vendors":["Advantech "]},"summary":"Low-level users can access and load local file contents in Advantech R-SeeNet due to improper control of file names or paths.","url":"https://insights.sbomify.com/CVE-2023-3256/"}
