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-2023-6263 in the wild and no public exploit code.\n\nAffected product: Network Optix NxCloud. 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-2023-6263/ (Markdown: https://insights.sbomify.com/CVE-2023-6263/index.md)","id":"CVE-2023-6263","markdown":"https://insights.sbomify.com/CVE-2023-6263/index.md","name":"CVE-2023-6263","record":{"aliases":["GHSA-xh6m-2h5x-55mh"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"NxCloud VMS","requires_auth":"none","summary":"Attackers can spoof VMS servers to steal authorization headers from legitimate users, potentially leading to account takeover.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NX","cpe":[{"product":"nxcloud","vendor":"networkoptix"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"An issue was discovered by IPVM team in Network Optix NxCloud before 23.1.0.40440. It was possible to add a fake VMS server to NxCloud by using the exact identification of a legitimate VMS server.
