An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-7494 in the wild and no public exploit code.\n\nAffected product: ICS-CERT Delta Electronics WPLSoft. 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-2018-7494/ (Markdown: https://insights.sbomify.com/CVE-2018-7494/index.md)","id":"CVE-2018-7494","markdown":"https://insights.sbomify.com/CVE-2018-7494/index.md","name":"CVE-2018-7494","record":{"aliases":["GHSA-xp2m-h7vm-6whw"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Delta Electronics WPLSoft","requires_auth":"none","summary":"A stack buffer overflow in Delta Electronics WPLSoft allows remote attackers to execute arbitrary code or crash the application via a crafted file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"wplsoft","vendor":"deltaww"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"WPLSoft in Delta Electronics versions 2.45.0 and prior utilizes a fixed length stack buffer where a value larger than the buffer can be read from a file into the buffer, causing the buffer to be overwritten, which may allow remote code execution or cause the application to crash.","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":"Memory corruption in Delta Electronics WPLSoft","id":"CVE-2018-7494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in WebAccess","id":"CVE-2018-7495"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2018-7493"},"products":["Delta Electronics WPLSoft"],"published":"2018-05-04","related":[{"cvss_score":8.8,"headline":"Memory corruption in Delta Electronics WPLSoft","id":"CVE-2018-7507","kev_date_added":null,"published":"2018-05-04"},{"cvss_score":8.8,"headline":"Memory corruption in Delta Electronics WPLSoft","id":"CVE-2018-7509","kev_date_added":null,"published":"2018-05-04"},{"cvss_score":8.2,"headline":"Delta Electronics WPLSoft Buffer-Overflow","id":"CVE-2023-5130","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":3.7,"headline":"Delta Electronics WPLSoft Modbus cleartext transmission","id":"CVE-2023-5461","kev_date_added":null,"published":"2023-10-09"},{"cvss_score":3.5,"headline":"Delta Electronics WPLSoft Modbus Data Packet heap-based overflow","id":"CVE-2023-5460","kev_date_added":null,"published":"2023-10-09"}],"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":"2024-09-16","vendors":["ICS-CERT"]},"summary":"A stack buffer overflow in Delta Electronics WPLSoft allows remote attackers to execute arbitrary code or crash the application via a crafted file.","url":"https://insights.sbomify.com/CVE-2018-7494/"}
