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-2020-26867 in the wild and no public exploit code.\n\nAffected product: ARC Informatique PcVue. 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-2020-26867/ (Markdown: https://insights.sbomify.com/CVE-2020-26867/index.md)","id":"CVE-2020-26867","markdown":"https://insights.sbomify.com/CVE-2020-26867/index.md","name":"CVE-2020-26867","record":{"aliases":["GHSA-7x49-vpw9-2vmr"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PcVue SCADA software","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on the web and mobile back-end server via unsafe deserialization in PcVue.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Kaspersky","cpe":[{"product":"pcvue","vendor":"arcinfo"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-502","name":"Deserialization of Untrusted Data"}],"description":"ARC Informatique PcVue prior to version 12.0.17 is vulnerable due to the deserialization of untrusted data, which may allow an attacker to remotely execute arbitrary code on the web and mobile back-end server.","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":"ARC Informatique PcVue Deserialization of Untrusted Data","id":"CVE-2020-26867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":0,"n_references":5,"next":{"headline":"ARC Informatique PcVue Access to Critical Private Variable via Public Method","id":"CVE-2020-26868"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-26866"},"products":["PcVue"],"published":"2020-10-12","related":[{"cvss_score":8.4,"headline":"Weak encryption mechanism for User directory","id":"CVE-2026-14868","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":7.5,"headline":"ARC Informatique PcVue Access to Critical Private Variable via Public Method","id":"CVE-2020-26868","kev_date_added":null,"published":"2020-10-12"},{"cvss_score":7.5,"headline":"ARC Informatique PcVue Exposure of Sensitive Information to an Unauthorized Actor","id":"CVE-2020-26869","kev_date_added":null,"published":"2020-10-12"},{"cvss_score":6.8,"headline":"Insecure password storage in User directory","id":"CVE-2026-14867","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":5.5,"headline":"Information disclosure in PcVue","id":"CVE-2022-4312","kev_date_added":null,"published":"2022-12-12"},{"cvss_score":5.5,"headline":"ARC Informatique PcVue","id":"CVE-2022-2569","kev_date_added":null,"published":"2022-08-24"}],"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":["ARC Informatique"]},"summary":"Remote attackers can execute arbitrary code on the web and mobile back-end server via unsafe deserialization in PcVue.","url":"https://insights.sbomify.com/CVE-2020-26867/"}
