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-2023-3042 in the wild and no public exploit code.\n\nAffected product: Dotcms Dotcms. 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-2023-3042/ (Markdown: https://insights.sbomify.com/CVE-2023-3042/index.md)","id":"CVE-2023-3042","markdown":"https://insights.sbomify.com/CVE-2023-3042/index.md","name":"CVE-2023-3042","record":{"aliases":["GHSA-4473-7649-rj9x"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"dotCMS core","requires_auth":"none","summary":"Attackers can bypass XSS and access controls by using double slashes in URLs, potentially executing malicious scripts or accessing restricted resources.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dotCMS","cpe":[{"product":"dotcms","vendor":"dotcms"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In dotCMS, versions mentioned, a flaw in the NormalizationFilter does not strip double slashes (//) from URLs, potentially enabling bypasses for XSS and access controls.
