It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-42855 and fix it if it is affected.\n\nWhat it is: CVE-2021-42855 is a high-severity vulnerability in Aternity SteelCentral AppInternals Dynamic Sampling Agent, published on 9 Mar 2022. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42855 in the wild and no public exploit code.\n\nAffected product: Aternity SteelCentral AppInternals Dynamic Sampling Agent. 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-2021-42855/ (Markdown: https://insights.sbomify.com/CVE-2021-42855/index.md)","id":"CVE-2021-42855","markdown":"https://insights.sbomify.com/CVE-2021-42855/index.md","name":"CVE-2021-42855","record":{"aliases":["GHSA-j285-2pfr-phwh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AppInternals Dynamic Sampling Agent","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges and execute arbitrary commands by modifying the misconfigured .debug_command.config file used by the agent.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GovTech CSG","cpe":[{"product":"steelcentral_appinternals_dynamic_sampling_agent","vendor":"riverbed"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"It was discovered that the SteelCentral AppInternals Dynamic Sampling Agent (DSA) uses the \".debug_command.config\" file to store a json string that contains a list of IDs and pre-configured commands.
