Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4987 in the wild and no public exploit code.\n\nAffected product: IBM FlashSystem 900. 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-2020-4987/ (Markdown: https://insights.sbomify.com/CVE-2020-4987/index.md)","id":"CVE-2020-4987","markdown":"https://insights.sbomify.com/CVE-2020-4987/index.md","name":"CVE-2020-4987","record":{"aliases":["GHSA-ccmm-6836-3vxj"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM FlashSystem GUI","requires_auth":"low_privilege","summary":"Stored XSS in IBM FlashSystem 900 GUI allows attackers to inject JavaScript, potentially stealing credentials from trusted sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"flashsystem_900_firmware","vendor":"ibm"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/A:N/UI:N/S:C/AC:L/I:L/PR:L/AV:N/C:L/RL:O/RC:C/E:H","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The IBM FlashSystem 900 user management GUI is vulnerable to stored cross-site scripting in code versions 1.5.2.8 and prior and 1.6.1.2 and prior.
