An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-40706 and fix it if it is affected.\n\nWhat it is: CVE-2023-40706 is a high-severity authentication bypass vulnerability in OPTO 22 SNAP PAC S1, published on 24 Aug 2023. 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-2023-40706 in the wild and no public exploit code.\n\nAffected product: OPTO 22 SNAP PAC S1. 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-2023-40706/ (Markdown: https://insights.sbomify.com/CVE-2023-40706/index.md)","id":"CVE-2023-40706","markdown":"https://insights.sbomify.com/CVE-2023-40706/index.md","name":"CVE-2023-40706","record":{"aliases":["GHSA-245g-9f78-5jxc"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"SNAP PAC S1","requires_auth":"none","summary":"Attackers can brute-force login credentials on the SNAP PAC S1 web server due to missing rate limiting, potentially gaining unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Dragos","cpe":[{"product":"snap_pac_s1_firmware","vendor":"opto22"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"There is no limit on the number of login attempts in the web server for the SNAP PAC S1 Firmware version R10.3b.
