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-2016-2783 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2016-2783/ (Markdown: https://insights.sbomify.com/CVE-2016-2783/index.md)","id":"CVE-2016-2783","markdown":"https://insights.sbomify.com/CVE-2016-2783/index.md","name":"CVE-2016-2783","record":{"aliases":["GHSA-3mgw-r2j9-j49w"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Avaya VSP OS","requires_auth":"none","summary":"Remote attackers can obtain unauthorized access to Avaya Fabric Connect VSP devices by sending crafted Ethernet frames due to improper index handling.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vsp_operating_system_software","vendor":"avaya"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-19","name":null}],"description":"Avaya Fabric Connect Virtual Services Platform (VSP) Operating System Software (VOSS) before 4.2.3.0 and 5.x before 5.0.1.0 does not properly handle VLAN and I-SIS indexes, which allows remote attackers to obtain unauthorized access via crafted Ethernet frames.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2019-01-17","github_poc":1,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-01-17T14:35:11Z","kind":"github_poc","ref":"https://github.com/iknowjason/spb","stars":2,"title":"Shortest Path Bridging (SPB-Mac) vulnerability testing scripts.
