An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-32540 in the wild and no public exploit code.\n\nAffected product: Advantech WebAccess/SCADA. 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-2023-32540/ (Markdown: https://insights.sbomify.com/CVE-2023-32540/index.md)","id":"CVE-2023-32540","markdown":"https://insights.sbomify.com/CVE-2023-32540/index.md","name":"CVE-2023-32540","record":{"aliases":["GHSA-g8xw-m45c-jphf"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA software","requires_auth":"high_privilege","summary":"Attackers can overwrite arbitrary files and inject code into XLS files in Advantech WebAccess/SCADA, leading to arbitrary code execution.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess\\/scada","vendor":"advantech"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"In Advantech WebAccss/SCADA v9.1.3 and prior, there is an arbitrary file overwrite vulnerability, which could allow an attacker to overwrite any file in the operating system (including system files), inject code into an XLS file, and modify the file extension, which could lead to arbitrary code execution.","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":"Code injection in WebAccess/SCADA","id":"CVE-2023-32540","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Hancom Office 2020","id":"CVE-2023-32541"},"packages":[],"prev":{"headline":"Horner Automation Cscape Out-of-bounds Write","id":"CVE-2023-32539"},"products":["WebAccess/SCADA"],"published":"2023-06-05","related":[{"cvss_score":9.8,"headline":"CVE-2023-1437","id":"CVE-2023-1437","kev_date_added":null,"published":"2023-08-02"},{"cvss_score":9.8,"headline":"Memory corruption in WebAccess/SCADA","id":"CVE-2021-32943","kev_date_added":null,"published":"2021-08-10"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2019-6519","kev_date_added":null,"published":"2019-02-05"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2019-6523","kev_date_added":null,"published":"2019-02-05"},{"cvss_score":8.8,"headline":"Privilege escalation in Advantech WebAccess/SCADA","id":"CVE-2021-22669","kev_date_added":null,"published":"2021-04-26"},{"cvss_score":8.8,"headline":"Privilege escalation in Advantech","id":"CVE-2020-13554","kev_date_added":null,"published":"2021-03-03"},{"cvss_score":8.8,"headline":"Path traversal in Advantech WebAccess/SCADA","id":"CVE-2020-25161","kev_date_added":null,"published":"2021-02-23"}],"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":"2025-01-08","vendors":["Advantech"]},"summary":"Attackers can overwrite arbitrary files and inject code into XLS files in Advantech WebAccess/SCADA, leading to arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2023-32540/"}
