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-2021-38177 in the wild and no public exploit code.\n\nAffected product: SAP CommonCryptoLib. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-38177/ (Markdown: https://insights.sbomify.com/CVE-2021-38177/index.md)","id":"CVE-2021-38177","markdown":"https://insights.sbomify.com/CVE-2021-38177/index.md","name":"CVE-2021-38177","record":{"aliases":["GHSA-4m93-727g-c564"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP CommonCryptoLib","requires_auth":"none","summary":"An unauthenticated attacker can crash the SAP application by sending crafted HTTP requests, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"commoncryptolib","vendor":"sap"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"SAP CommonCryptoLib version 8.5.38 or lower is vulnerable to null pointer dereference vulnerability when an unauthenticated attacker sends crafted malicious data in the HTTP requests over the network, this causes the SAP application to crash and has high impact on the availability of the SAP system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Null dereference in SAP CommonCryptoLib","id":"CVE-2021-38177","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Business logic in SAP NetWeaver AS ABAP and ABAP Platform","id":"CVE-2021-38178"},"packages":[],"prev":{"headline":"SQL injection in SAP LT Replication Server","id":"CVE-2021-38176"},"products":["SAP CommonCryptoLib"],"published":"2021-09-14","related":[{"cvss_score":9.8,"headline":"Missing Authorization check in SAP CommonCryptoLib","id":"CVE-2023-40309","kev_date_added":null,"published":"2023-09-12"},{"cvss_score":7.5,"headline":"Memory Corruption vulnerability in SAP CommonCryptoLib","id":"CVE-2023-40308","kev_date_added":null,"published":"2023-09-12"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2014-8587","kev_date_added":null,"published":"2014-11-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":["SAP SE"]},"summary":"An unauthenticated attacker can crash the SAP application by sending crafted HTTP requests, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2021-38177/"}
