Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-51747 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.james:james-server (Maven): affected all versions; fixed in 3.7.5\n- org.apache.james:james-server (Maven): affected all versions; fixed in 3.7.5\n- org.apache.james:james-server (Maven): affected from 3.8.0; fixed in 3.8.1\n- org.apache.james:james-server (Maven): affected from 3.8.0; fixed in 3.8.1\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-2023-51747/ (Markdown: https://insights.sbomify.com/CVE-2023-51747/index.md)","id":"CVE-2023-51747","markdown":"https://insights.sbomify.com/CVE-2023-51747/index.md","name":"CVE-2023-51747","record":{"aliases":["GHSA-p5q9-86w4-2xr5"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Mail server","requires_auth":"low_privilege","summary":"Attackers can forge SMTP envelopes to bypass SPF checks due to lenient line delimiter handling in Apache James mail server.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"james","vendor":"apache"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"},{"id":"CWE-290","name":"Authentication Bypass by Spoofing"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Apache James prior to versions 3.8.1 and 3.7.5 is vulnerable to SMTP smuggling.\n\nA lenient behaviour in line delimiter handling might create a difference of interpretation between the sender and the receiver which can be exploited by an attacker to forge an SMTP envelop, allowing for instance to bypass SPF checks.\n\nThe patch implies enforcement of CRLF as a line delimiter as part of the DATA transaction.\n\nWe recommend James users to upgrade to non vulnerable versions.","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":"SMTP smuggling in Apache James","id":"CVE-2023-51747","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"other","year":"2023"},"n_packages":4,"n_references":4,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2023-51748"},"packages":[{"ecosystem":"Maven","fixed":["3.7.5"],"introduced":["0"],"last_affected":[],"package":"org.apache.james:james-server","purl":null,"source":"GHSA-p5q9-86w4-2xr5"},{"ecosystem":"Maven","fixed":["3.7.5"],"introduced":["0"],"last_affected":[],"package":"org.apache.james:james-server","purl":"pkg:maven/org.apache.james/james-server","source":"GHSA-p5q9-86w4-2xr5"},{"ecosystem":"Maven","fixed":["3.8.1"],"introduced":["3.8.0"],"last_affected":[],"package":"org.apache.james:james-server","purl":null,"source":"GHSA-p5q9-86w4-2xr5"},{"ecosystem":"Maven","fixed":["3.8.1"],"introduced":["3.8.0"],"last_affected":[],"package":"org.apache.james:james-server","purl":"pkg:maven/org.apache.james/james-server","source":"GHSA-p5q9-86w4-2xr5"}],"prev":{"headline":"Memory corruption in JT2Go","id":"CVE-2023-51746"},"products":["Apache James server"],"published":"2024-02-27","related":[{"cvss_score":9.8,"headline":"Apache James server: Privilege escalation via JMX pre-authentication deserialisation","id":"CVE-2023-51518","kev_date_added":null,"published":"2024-02-27"},{"cvss_score":9.8,"headline":"Vulnerability that affects org.apache.pdfbox:pdfbox","id":"CVE-2019-0228","kev_date_added":null,"published":"2019-04-17"},{"cvss_score":9.1,"headline":"Sieve file storage vulnerable to path traversal attacks","id":"CVE-2021-40525","kev_date_added":null,"published":"2022-01-04"},{"cvss_score":7.8,"headline":"Apache James server: Privilege escalation through unauthenticated JMX","id":"CVE-2023-26269","kev_date_added":null,"published":"2023-04-03"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2006-2806","kev_date_added":null,"published":"2006-06-05"},{"cvss_score":7.5,"headline":"STARTTLS command injection in Apache JAMES","id":"CVE-2022-28220","kev_date_added":null,"published":"2022-09-08"},{"cvss_score":7.5,"headline":"Apache James IMAP vulnerable to a ReDoS","id":"CVE-2021-40110","kev_date_added":null,"published":"2022-01-04"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Apache Software Foundation"]},"summary":"Attackers can forge SMTP envelopes to bypass SPF checks due to lenient line delimiter handling in Apache James mail server.","url":"https://insights.sbomify.com/CVE-2023-51747/"}
