An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-5726 and fix it if it is affected.\n\nWhat it is: CVE-2020-5726 is a high-severity SQL injection vulnerability in Grandstream UCM6200 series, published on 30 Mar 2020. 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-2020-5726 in the wild and no public exploit code.\n\nAffected product: Grandstream UCM6200 series. 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-2020-5726/ (Markdown: https://insights.sbomify.com/CVE-2020-5726/index.md)","id":"CVE-2020-5726","markdown":"https://insights.sbomify.com/CVE-2020-5726/index.md","name":"CVE-2020-5726","record":{"aliases":["GHSA-j8g2-wfvh-q3pf"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Grandstream UCM6200","requires_auth":"none","summary":"Remote unauthenticated attackers can exploit SQL injection in the CTI server to discover user passwords on Grandstream UCM6200 devices.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"ucm6202_firmware","vendor":"grandstream"},{"product":"ucm6204_firmware","vendor":"grandstream"},{"product":"ucm6208_firmware","vendor":"grandstream"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"The Grandstream UCM6200 series before 1.0.20.22 is vulnerable to an SQL injection via the CTI server on port 8888.
