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-2021-25640 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.dubbo:dubbo (Maven): affected from 2.5.0; fixed in 2.7.10\n- org.apache.dubbo:dubbo (Maven): affected from 2.5.0; fixed in 2.7.10\n- com.alibaba:dubbo (Maven): affected from 2.5.0; fixed in 2.6.9\n- com.alibaba:dubbo (Maven): affected from 2.5.0; fixed in 2.6.9\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-2021-25640/ (Markdown: https://insights.sbomify.com/CVE-2021-25640/index.md)","id":"CVE-2021-25640","markdown":"https://insights.sbomify.com/CVE-2021-25640/index.md","name":"CVE-2021-25640","record":{"aliases":["GHSA-gw4j-4229-q4px"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java RPC framework","requires_auth":"none","summary":"Attackers can bypass host whitelisting in Apache Dubbo to perform Server-Side Request Forgery or open redirects via the parseURL method.","user_interaction":"required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"dubbo","vendor":"apache"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","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-601","name":"URL Redirection to Untrusted Site"},{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"In Apache Dubbo prior to 2.6.9 and 2.7.9, the usage of parseURL method will lead to the bypass of white host check which can cause open redirect or SSRF vulnerability.","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":"Open Redirect or SSRF vulnerability usage of parseURL","id":"CVE-2021-25640","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"ssrf","year":"2021"},"n_packages":4,"n_references":2,"next":{"headline":"Dubbo Zookeeper does not check serialization id","id":"CVE-2021-25641"},"packages":[{"ecosystem":"Maven","fixed":["2.6.9"],"introduced":["2.5.0"],"last_affected":[],"package":"com.alibaba:dubbo","purl":null,"source":"GHSA-gw4j-4229-q4px"},{"ecosystem":"Maven","fixed":["2.6.9"],"introduced":["2.5.0"],"last_affected":[],"package":"com.alibaba:dubbo","purl":"pkg:maven/com.alibaba/dubbo","source":"GHSA-gw4j-4229-q4px"},{"ecosystem":"Maven","fixed":["2.7.10"],"introduced":["2.5.0"],"last_affected":[],"package":"org.apache.dubbo:dubbo","purl":null,"source":"GHSA-gw4j-4229-q4px"},{"ecosystem":"Maven","fixed":["2.7.10"],"introduced":["2.5.0"],"last_affected":[],"package":"org.apache.dubbo:dubbo","purl":"pkg:maven/org.apache.dubbo/dubbo","source":"GHSA-gw4j-4229-q4px"}],"prev":{"headline":"Incorrect trust validation of signature with ambiguous KeyInfo children","id":"CVE-2021-25636"},"products":["Apache Dubbo"],"published":"2021-05-31","related":[{"cvss_score":9.8,"headline":"Bypass serialize checks in Apache Dubbo","id":"CVE-2023-29234","kev_date_added":null,"published":"2023-12-15"},{"cvss_score":9.8,"headline":"Apache Dubbo: Bypass deny serialize list check in Apache Dubbo","id":"CVE-2023-46279","kev_date_added":null,"published":"2023-12-15"},{"cvss_score":9.8,"headline":"Regular expression Denial of Service in MooTools","id":"CVE-2021-32824","kev_date_added":null,"published":"2023-01-03"},{"cvss_score":9.8,"headline":"Apache Dubbo Hession Deserialization Vulnerability Gadgets Bypass","id":"CVE-2022-39198","kev_date_added":null,"published":"2022-10-18"},{"cvss_score":9.8,"headline":"Dubbo Hessian cause RCE when parse error","id":"CVE-2021-43297","kev_date_added":null,"published":"2022-01-10"},{"cvss_score":9.8,"headline":"Unprotected input value toString cause RCE","id":"CVE-2021-36161","kev_date_added":null,"published":"2021-09-09"},{"cvss_score":9.8,"headline":"Bypass deserialization checks in Apache Dubbo","id":"CVE-2021-37579","kev_date_added":null,"published":"2021-09-09"}],"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":"2024-08-03","vendors":["Apache Software Foundation"]},"summary":"Attackers can bypass host whitelisting in Apache Dubbo to perform Server-Side Request Forgery or open redirects via the parseURL method.","url":"https://insights.sbomify.com/CVE-2021-25640/"}
