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-2020-26868 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-2020-26868/ (Markdown: https://insights.sbomify.com/CVE-2020-26868/index.md)","id":"CVE-2020-26868","markdown":"https://insights.sbomify.com/CVE-2020-26868/index.md","name":"CVE-2020-26868","record":{"aliases":["GHSA-hmv8-293h-5vrj"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA software","requires_auth":"none","summary":"An unauthorized user can modify validation information, leading to denial of service and data modification in PcVue SCADA systems.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Kaspersky","cpe":[{"product":"pcvue","vendor":"arcinfo"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"},{"id":"CWE-767","name":"Access to Critical Private Variable via Public Method"}],"description":"ARC Informatique PcVue prior to version 12.0.17 is vulnerable to a denial-of-service attack due to the ability of an unauthorized user to modify information used to validate messages sent by legitimate web clients.
