It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15777 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.gradle:gradle-enterprise-maven-extension (Maven): affected all versions; fixed in 1.6\n- com.gradle:gradle-enterprise-maven-extension (Maven): affected all versions; fixed in 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-2020-15777/ (Markdown: https://insights.sbomify.com/CVE-2020-15777/index.md)","id":"CVE-2020-15777","markdown":"https://insights.sbomify.com/CVE-2020-15777/index.md","name":"CVE-2020-15777","record":{"aliases":["GHSA-vp55-fhxx-vcx8"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Gradle Enterprise plugin","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution and local privilege escalation via unsafe Java deserialization in the Gradle Enterprise Maven Extension plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"maven","vendor":"gradle"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"An issue was discovered in the Maven Extension plugin before 1.6 for Gradle Enterprise. The extension uses a socket connection to send serialized Java objects. Deserialization is not restricted to an allow-list, thus allowing an attacker to achieve code execution via a malicious deserialization gadget chain. The socket is not bound exclusively to localhost. The port this socket is assigned to is randomly selected and is not intentionally exposed to the public (either by design or documentation). This could potentially be used to achieve remote code execution and local privilege escalation.","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":"Maven Extension plugin for Gradle Enterprise vulnerable to Deserialization of Untrusted Data","id":"CVE-2020-15777","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Command injection in n/a","id":"CVE-2020-15778"},"packages":[{"ecosystem":"Maven","fixed":["1.6"],"introduced":["0"],"last_affected":[],"package":"com.gradle:gradle-enterprise-maven-extension","purl":null,"source":"GHSA-vp55-fhxx-vcx8"},{"ecosystem":"Maven","fixed":["1.6"],"introduced":["0"],"last_affected":[],"package":"com.gradle:gradle-enterprise-maven-extension","purl":"pkg:maven/com.gradle/gradle-enterprise-maven-extension","source":"GHSA-vp55-fhxx-vcx8"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-15776"},"products":["n/a"],"published":"2020-08-25","related":[],"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 achieve remote code execution and local privilege escalation via unsafe Java deserialization in the Gradle Enterprise Maven Extension plugin.","url":"https://insights.sbomify.com/CVE-2020-15777/"}
