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-2007-5640 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-2007-5640/ (Markdown: https://insights.sbomify.com/CVE-2007-5640/index.md)","id":"CVE-2007-5640","markdown":"https://insights.sbomify.com/CVE-2007-5640/index.md","name":"CVE-2007-5640","record":{"aliases":["GHSA-v3jg-64qp-m2qp"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nortel IP Phone","requires_auth":"none","summary":"Remote attackers can block calls and force re-registration on Nortel IP phones by sending spoofed resume messages to the Signaling Server.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"business_communications_manager","vendor":"nortel"},{"product":"centrex_ip_client_manager","vendor":"nortel"},{"product":"centrex_ip_element_manager","vendor":"nortel"},{"product":"meridian_option_11c","vendor":"nortel"},{"product":"meridian_option_51c","vendor":"nortel"},{"product":"meridian_option_61c","vendor":"nortel"},{"product":"meridian_option_81c","vendor":"nortel"},{"product":"meridian_sl100","vendor":"nortel"},{"product":"mobile_voice_client_2050","vendor":"nortel"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[],"description":"The Nortel UNIStim IP Softphone 2050, IP Phone 1140E, and additional Nortel products from the IP Phone, Business Communications Manager (BCM), Mobile Voice Client, and other product lines, allow remote attackers to block calls and force re-registration via a resume message to the Signaling Server that has a spoofed source IP address for the phone.
