An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-5243 and fix it if it is affected.\n\nWhat it is: CVE-2018-5243 is a high-severity denial of service vulnerability in Symantec Encryption Management Server (SEMS), published on 20 Aug 2018. 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-2018-5243 in the wild and no public exploit code.\n\nAffected product: Symantec Encryption Management Server (SEMS). 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-2018-5243/ (Markdown: https://insights.sbomify.com/CVE-2018-5243/index.md)","id":"CVE-2018-5243","markdown":"https://insights.sbomify.com/CVE-2018-5243/index.md","name":"CVE-2018-5243","record":{"aliases":["GHSA-w8qw-x88f-f35r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Symantec Encryption Management Server","requires_auth":"none","summary":"Attackers can disrupt services on Symantec Encryption Management Server, causing denial of service for intended users.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"symantec","cpe":[{"product":"encryption_management_server","vendor":"symantec"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The Symantec Encryption Management Server (SEMS) product, prior to version 3.4.2 MP1, may be susceptible to a denial of service (DoS) exploit.
