An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-25226 exists.\n\nAffected product: ThinVNC. 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-2022-25226/ (Markdown: https://insights.sbomify.com/CVE-2022-25226/index.md)","id":"CVE-2022-25226","markdown":"https://insights.sbomify.com/CVE-2022-25226/index.md","name":"CVE-2022-25226","record":{"aliases":["GHSA-mvv3-c6h9-hj2q"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VNC server","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication in ThinVNC to gain server access and execute arbitrary code via input events.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[{"product":"thinvnc","vendor":"cybelsoft"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"ThinVNC version 1.0b1 allows an unauthenticated user to bypass the authentication process via 'http://thin-vnc:8080/cmd?cmd=connect' by obtaining a valid SID without any kind of authentication.
