An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-0858 and fix it if it is affected.\n\nWhat it is: CVE-2023-0858 is a low-severity authentication bypass vulnerability in Canon Office/Small Office Multifunction Printers and Laser Printers, published on 11 May 2023. 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-2023-0858 in the wild and no public exploit code.\n\nAffected product: Canon Office/Small Office Multifunction Printers and Laser Printers. 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-2023-0858/ (Markdown: https://insights.sbomify.com/CVE-2023-0858/index.md)","id":"CVE-2023-0858","markdown":"https://insights.sbomify.com/CVE-2023-0858/index.md","name":"CVE-2023-0858","record":{"aliases":["GHSA-fg53-q2jq-9xxq"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Canon multifunction printer","requires_auth":"none","summary":"An attacker on the network can bypass authentication to gain unauthorized access to Canon multifunction printers and laser printers.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Canon","cpe":[{"product":"i-sensys_lbp621cw_firmware","vendor":"canon"},{"product":"i-sensys_lbp623cdw_firmware","vendor":"canon"},{"product":"i-sensys_lbp633cdw_firmware","vendor":"canon"},{"product":"i-sensys_lbp664cx_firmware","vendor":"canon"},{"product":"i-sensys_mf641cw_firmware","vendor":"canon"},{"product":"i-sensys_mf643cdw_firmware","vendor":"canon"},{"product":"i-sensys_mf645cx_firmware","vendor":"canon"},{"product":"i-sensys_mf742cdw_firmware","vendor":"canon"},{"product":"i-sensys_mf744cdw_firmware","vendor":"canon"},{"product":"i-sensys_mf746cx_firmware","vendor":"canon"},{"product":"i-sensys_x_c1127i_firmware","vendor":"canon"},{"product":"i-sensys_x_c1127if_firmware","vendor":"canon"},{"product":"i-sensys_x_c1127p_firmware","vendor":"canon"},{"product":"imageprograf_tc-20_firmware","vendor":"canon"},{"product":"imageprograf_tc-20m_firmware","vendor":"canon"},{"product":"lbp1127c_firmware","vendor":"canon"},{"product":"lbp122dw_firmware","vendor":"canon"},{"product":"lbp621c_firmware","vendor":"canon"},{"product":"lbp622c_firmware","vendor":"canon"},{"product":"lbp622cdw_firmware","vendor":"canon"},{"product":"lbp623cdw_firmware","vendor":"canon"},{"product":"lbp661c_firmware","vendor":"canon"},{"product":"lbp662c_firmware","vendor":"canon"},{"product":"lbp664c_firmware","vendor":"canon"},{"product":"lbp664cdw_firmware","vendor":"canon"},{"product":"maxify_gx3020_firmware","vendor":"canon"},{"product":"maxify_gx4020_firmware","vendor":"canon"},{"product":"mf1127c_firmware","vendor":"canon"},{"product":"mf262dw_ii_firmware","vendor":"canon"},{"product":"mf264dw_ii_firmware","vendor":"canon"},{"product":"mf267dw_ii_firmware","vendor":"canon"},{"product":"mf269dw_ii_firmware","vendor":"canon"},{"product":"mf269dw_vp_ii_firmware","vendor":"canon"},{"product":"mf272dw_firmware","vendor":"canon"},{"product":"mf273dw_firmware","vendor":"canon"},{"product":"mf275dw_firmware","vendor":"canon"},{"product":"mf641cw_firmware","vendor":"canon"},{"product":"mf642cdw_firmware","vendor":"canon"},{"product":"mf644cdw_firmware","vendor":"canon"},{"product":"mf741cdw_firmware","vendor":"canon"},{"product":"mf743cdw_firmware","vendor":"canon"},{"product":"mf745cdw_firmware","vendor":"canon"},{"product":"mf746cdw_firmware","vendor":"canon"},{"product":"pixma_g3270_firmware","vendor":"canon"},{"product":"pixma_g4270_firmware","vendor":"canon"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper Authentication of RemoteUI of Office / Small Office Multifunction Printers and Laser Printers(*) which may allow an attacker on the network segment to trigger unauthorized access to the product. *:Satera LBP660C Series/LBP620C Series/MF740C Series/MF640C Series firmware Ver.11.04 and earlier sold in Japan.
