It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-4138 exists.\n\nAffected packages and fixed versions:\n- rdiffweb (PyPI): affected all versions; fixed in 2.8.1\n- rdiffweb (PyPI): affected all versions; fixed in 2.8.1\n- rdiffweb (PyPI): affected all versions; fixed in 2.8.1\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-2023-4138/ (Markdown: https://insights.sbomify.com/CVE-2023-4138/index.md)","id":"CVE-2023-4138","markdown":"https://insights.sbomify.com/CVE-2023-4138/index.md","name":"CVE-2023-4138","record":{"aliases":["GHSA-wwrg-2w5j-grvx","PYSEC-2026-1863"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"rdiffweb web application","requires_auth":"high_privilege","summary":"An attacker can cause a denial of service in rdiffweb by exhausting resources due to missing limits.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"rdiffweb","vendor":"ikus-soft"}],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Allocation of Resources Without Limits or Throttling in GitHub repository ikus060/rdiffweb prior to 2.8.0.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Allocation of Resources Without Limits or Throttling in ikus060/rdiffweb","id":"CVE-2023-4138","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":3,"n_references":2,"next":{"headline":"WP Ultimate CSV Importer \u003c= 7.9.8 - Sensitive Information Exposure via Directory Listing","id":"CVE-2023-4139"},"packages":[{"ecosystem":"PyPI","fixed":["2.8.1"],"introduced":["0"],"last_affected":[],"package":"rdiffweb","purl":null,"source":"GHSA-wwrg-2w5j-grvx"},{"ecosystem":"PyPI","fixed":["2.8.1"],"introduced":["0"],"last_affected":[],"package":"rdiffweb","purl":"pkg:pypi/rdiffweb","source":"GHSA-wwrg-2w5j-grvx"},{"ecosystem":"PyPI","fixed":["2.8.1"],"introduced":["0"],"last_affected":[],"package":"rdiffweb","purl":"pkg:pypi/rdiffweb","source":"PYSEC-2026-1863"}],"prev":{"headline":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Crafter Engine","id":"CVE-2023-4136"},"products":["ikus060/rdiffweb"],"published":"2023-08-03","related":[{"cvss_score":10,"headline":"Improper Restriction of Rendered UI Layers or Frames in ikus060/rdiffweb","id":"CVE-2022-3167","kev_date_added":null,"published":"2022-09-08"},{"cvss_score":8.8,"headline":"Cross-Site Request Forgery (CSRF) in ikus060/rdiffweb","id":"CVE-2022-3221","kev_date_added":null,"published":"2022-09-15"},{"cvss_score":8.4,"headline":"Improper Access Control in ikus060/rdiffweb","id":"CVE-2022-4724","kev_date_added":null,"published":"2022-12-23"},{"cvss_score":8.2,"headline":"Path Traversal in ikus060/rdiffweb","id":"CVE-2022-3389","kev_date_added":null,"published":"2022-10-06"},{"cvss_score":7.5,"headline":"rdiffweb's lack of token name length limit can result in DoS or memory corruption","id":"CVE-2022-3371","kev_date_added":null,"published":"2022-09-30"},{"cvss_score":7.5,"headline":"Sensitive Cookie in HTTPS Session Without 'Secure' Attribute in ikus060/rdiffweb","id":"CVE-2022-3174","kev_date_added":null,"published":"2022-09-13"},{"cvss_score":7.2,"headline":"Authentication Bypass by Primary Weakness in ikus060/rdiffweb","id":"CVE-2022-4722","kev_date_added":null,"published":"2022-12-23"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-11","vendors":["ikus060"]},"summary":"An attacker can cause a denial of service in rdiffweb by exhausting resources due to missing limits.","url":"https://insights.sbomify.com/CVE-2023-4138/"}
