An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-12611 exists.\n\nAffected packages and fixed versions:\n- org.apache.struts:struts2-core (Maven): affected from 2.0.1; fixed in 2.3.34\n- org.apache.struts:struts2-core (Maven): affected from 2.0.1; fixed in 2.3.34\n- org.apache.struts:struts2-core (Maven): affected from 2.5.0; fixed in 2.5.11\n- org.apache.struts:struts2-core (Maven): affected from 2.5.0; fixed in 2.5.11\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-2017-12611/ (Markdown: https://insights.sbomify.com/CVE-2017-12611/index.md)","id":"CVE-2017-12611","markdown":"https://insights.sbomify.com/CVE-2017-12611/index.md","name":"CVE-2017-12611","record":{"aliases":["GHSA-8fx9-5hx8-crhm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Attackers can execute arbitrary code by exploiting improper input handling in Freemarker tags within Apache Struts applications.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"struts","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Apache Struts 2.0.0 through 2.3.33 and 2.5 through 2.5.10.1, using an unintentional expression in a Freemarker tag instead of string literals can lead to a RCE attack.","ecosystems":["Maven"],"exploits":{"exploitdb":1,"first_seen":"2017-09-08","github_poc":3,"max_poc_stars":37,"metasploit":0,"nuclei":1,"refs":[{"date":"2017-09-08T02:50:37Z","kind":"github_poc","ref":"https://github.com/brianwrf/S2-053-CVE-2017-12611","stars":37,"title":"A simple script for exploit RCE for Struts 2 S2-053(CVE-2017-12611)"},{"date":"2017-09-08","kind":"exploitdb","ref":"44556","stars":null,"title":"Apache Struts 2.0.1 \u003c 2.3.33 / 2.5 \u003c 2.5.10 -
