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-2020-1601 in the wild and no public exploit code.\n\nAffected product: Juniper Junos. 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-2020-1601/ (Markdown: https://insights.sbomify.com/CVE-2020-1601/index.md)","id":"CVE-2020-1601","markdown":"https://insights.sbomify.com/CVE-2020-1601/index.md","name":"CVE-2020-1601","record":{"aliases":["GHSA-p8w7-f589-855p"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Junos OS","requires_auth":"none","summary":"Malformed PCEP packets crash the pccd process on Junos OS devices, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"description":"Certain types of malformed Path Computation Element Protocol (PCEP) packets when received and processed by a Juniper Networks Junos OS device serving as a Path Computation Client (PCC) in a PCEP environment using Juniper's path computational element protocol daemon (pccd) process allows an attacker to cause the pccd process to crash and generate a core file thereby causing a Denial of Service (DoS).
