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-2019-25613 exists.\n\nAffected product: Echatserver Easy Chat. 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-2019-25613/ (Markdown: https://insights.sbomify.com/CVE-2019-25613/index.md)","id":"CVE-2019-25613","markdown":"https://insights.sbomify.com/CVE-2019-25613/index.md","name":"CVE-2019-25613","record":{"aliases":["GHSA-phg5-3h7x-599v"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Easy Chat Server","requires_auth":"none","summary":"Remote attackers can crash Easy Chat Server by sending oversized data in the message parameter, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"easy_chat_server","vendor":"echatserver"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"}],"description":"Easy Chat Server 3.1 contains a denial of service vulnerability that allows remote attackers to crash the application by sending oversized data in the message parameter.
