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-2020-1961 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.syncope:syncope-core (Maven): affected from 2.0.0; fixed in 2.0.15\n- org.apache.syncope:syncope-core (Maven): affected from 2.0.0; fixed in 2.0.15\n- org.apache.syncope:syncope-core (Maven): affected from 2.1.0; fixed in 2.1.6\n- org.apache.syncope:syncope-core (Maven): affected from 2.1.0; fixed in 2.1.6\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-2020-1961/ (Markdown: https://insights.sbomify.com/CVE-2020-1961/index.md)","id":"CVE-2020-1961","markdown":"https://insights.sbomify.com/CVE-2020-1961/index.md","name":"CVE-2020-1961","record":{"aliases":["GHSA-4w4p-xwrr-9crh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Syncope","requires_auth":"none","summary":"Attackers can inject arbitrary JEXL expressions into mail templates to achieve remote code execution in Apache Syncope.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"syncope","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Vulnerability to Server-Side Template Injection on Mail templates for Apache Syncope 2.0.X releases prior to 2.0.15, 2.1.X releases prior to 2.1.6, enabling attackers to inject arbitrary JEXL expressions, leading to Remote Code Execution (RCE) was discovered.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Injection in Apache Syncope","id":"CVE-2020-1961","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":4,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-1962"},"packages":[{"ecosystem":"Maven","fixed":["2.0.15"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":null,"source":"GHSA-4w4p-xwrr-9crh"},{"ecosystem":"Maven","fixed":["2.0.15"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":"pkg:maven/org.apache.syncope/syncope-core","source":"GHSA-4w4p-xwrr-9crh"},{"ecosystem":"Maven","fixed":["2.1.6"],"introduced":["2.1.0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":null,"source":"GHSA-4w4p-xwrr-9crh"},{"ecosystem":"Maven","fixed":["2.1.6"],"introduced":["2.1.0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":"pkg:maven/org.apache.syncope/syncope-core","source":"GHSA-4w4p-xwrr-9crh"}],"prev":{"headline":"Command injection in Apache Flink","id":"CVE-2020-1960"},"products":["Apache Syncope"],"published":"2020-05-04","related":[{"cvss_score":9.8,"headline":"Apache Syncope: Remote Code Execution via Flowable BPMN Groovy ScriptTask","id":"CVE-2026-53405","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: Remote Code Execution via Scripted Connector","id":"CVE-2026-53421","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: SQL injection vulnerability in Audit Events search","id":"CVE-2026-57308","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: User self-service privilege escalation","id":"CVE-2026-62183","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: RCE via Groovy Sandbox bypass","id":"CVE-2026-63071","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Expression Language Injection in Apache Syncope","id":"CVE-2020-1959","kev_date_added":null,"published":"2020-05-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject arbitrary JEXL expressions into mail templates to achieve remote code execution in Apache Syncope.","url":"https://insights.sbomify.com/CVE-2020-1961/"}
