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-2018-8845 in the wild and no public exploit code.\n\nAffected product: Advantech Webaccess. 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-2018-8845/ (Markdown: https://insights.sbomify.com/CVE-2018-8845/index.md)","id":"CVE-2018-8845","markdown":"https://insights.sbomify.com/CVE-2018-8845/index.md","name":"CVE-2018-8845","record":{"aliases":["GHSA-r2p8-8cx3-42qq"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA software","requires_auth":"none","summary":"Heap-based buffer overflow in Advantech WebAccess allows attackers to execute arbitrary code, posing a critical risk to industrial control systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess","vendor":"advantech"},{"product":"webaccess\\/nms","vendor":"advantech"},{"product":"webaccess_dashboard","vendor":"advantech"},{"product":"webaccess_scada","vendor":"advantech"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, a heap-based buffer overflow vulnerability has been identified, which may allow an attacker to execute arbitrary code.","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 WebAccess","id":"CVE-2018-8845","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"advantech:webaccess","products":["advantech:webaccess"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in e-Alert Unit (non-medical device)","id":"CVE-2018-8846"},"packages":[],"prev":{"headline":"Cross-site request forgery in e-Alert Unit (non-medical device)","id":"CVE-2018-8844"},"products":["WebAccess"],"published":"2018-05-15","related":[{"cvss_score":10,"headline":"Multiple stack-based buffer overflows in unspecified DLL files in Advantech WebAccess before 8.0.1 allow remote attackers to execute arbitra","id":"CVE-2014-9208","kev_date_added":null,"published":"2015-09-11"},{"cvss_score":9.8,"headline":"Advantech WebAccess","id":"CVE-2021-33023","kev_date_added":null,"published":"2021-10-18"},{"cvss_score":9.8,"headline":"Advantech WebAccess","id":"CVE-2021-38389","kev_date_added":null,"published":"2021-10-18"},{"cvss_score":9.8,"headline":"Memory corruption in Advantech WebAccess","id":"CVE-2021-38408","kev_date_added":null,"published":"2021-09-09"},{"cvss_score":9.8,"headline":"Memory corruption in WebAccess Node","id":"CVE-2020-12019","kev_date_added":null,"published":"2020-06-15"},{"cvss_score":9.8,"headline":"Memory corruption in Advantech WebAccess Node","id":"CVE-2020-10638","kev_date_added":null,"published":"2020-05-08"},{"cvss_score":9.8,"headline":"Memory corruption in Advantech WebAccess Node","id":"CVE-2020-12002","kev_date_added":null,"published":"2020-05-08"}],"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":"2024-09-17","vendors":["Advantech"]},"summary":"Heap-based buffer overflow in Advantech WebAccess allows attackers to execute arbitrary code, posing a critical risk to industrial control systems.","url":"https://insights.sbomify.com/CVE-2018-8845/"}
