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-2023-38556 in the wild and no public exploit code.\n\nAffected product: SEIKO EPSON printer Web Config. 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-2023-38556/ (Markdown: https://insights.sbomify.com/CVE-2023-38556/index.md)","id":"CVE-2023-38556","markdown":"https://insights.sbomify.com/CVE-2023-38556/index.md","name":"CVE-2023-38556","record":{"aliases":["GHSA-whxf-cw32-jmhm"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Epson printer Web Config","requires_auth":"none","summary":"A remote attacker can turn off the printer due to improper input validation in the Web Config interface.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"ep-801a_firmware","vendor":"epson"},{"product":"ep-802a_firmware","vendor":"epson"},{"product":"ep-901a_firmware","vendor":"epson"},{"product":"ep-901f_firmware","vendor":"epson"},{"product":"ep-902a_firmware","vendor":"epson"},{"product":"pa-tcu1_firmware","vendor":"epson"},{"product":"pm-t960_firmware","vendor":"epson"},{"product":"pm-t990_firmware","vendor":"epson"},{"product":"px-201_firmware","vendor":"epson"},{"product":"px-502a_firmware","vendor":"epson"},{"product":"px-601f_firmware","vendor":"epson"},{"product":"px-602f_firmware","vendor":"epson"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"Improper input validation vulnerability in SEIKO EPSON printer Web Config allows a remote attacker to turned off the printer.\r\n[Note] Web Config is the software that allows users to check the status and change the settings of SEIKO EPSON printers via a web browser.
