An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-4497 in the wild and no public exploit code.\n\nAffected product: EFS Software Easy Chat Server. 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-2023-4497/ (Markdown: https://insights.sbomify.com/CVE-2023-4497/index.md)","id":"CVE-2023-4497","markdown":"https://insights.sbomify.com/CVE-2023-4497/index.md","name":"CVE-2023-4497","record":{"aliases":["GHSA-j827-c7gh-xmmj"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Easy Chat Server","requires_auth":"none","summary":"Stored XSS in Easy Chat Server allows attackers to inject scripts via the Icon parameter, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[{"product":"easy_chat_server","vendor":"easy_chat_server_project"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Easy Chat Server, in its 3.1 version and before, does not sufficiently encrypt user-controlled inputs, resulting in a Cross-Site Scripting (XSS) vulnerability stored via /registresult.htm (POST method), in the Icon parameter.
