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-2021-47154 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-47154/ (Markdown: https://insights.sbomify.com/CVE-2021-47154/index.md)","id":"CVE-2021-47154","markdown":"https://insights.sbomify.com/CVE-2021-47154/index.md","name":"CVE-2021-47154","record":{"aliases":["DEBIAN-CVE-2021-47154","DLA-3770-1","GHSA-gpvh-42rv-p6wg","OESA-2024-1303","OESA-2024-1304","OESA-2024-1305","SUSE-SU-2024:1256-1","UBUNTU-CVE-2021-47154","USN-6712-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl Net::CIDR::Lite","requires_auth":"none","summary":"Attackers can bypass IP-based access controls by using leading zeros in IP addresses, affecting applications using the Perl Net::CIDR::Lite module.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[],"description":"The Net::CIDR::Lite module before 0.22 for Perl does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses.","ecosystems":["SUSE:Linux Enterprise Module for Development Tools 15 SP5","openSUSE:Leap 15.5"],"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":"Security feature bypass in n/a","id":"CVE-2021-47154","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":2,"n_references":5,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2021-47155"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Development Tools 15 SP5","fixed":["0.21-150100.6.3.1"],"introduced":["0"],"last_affected":[],"package":"perl-Net-CIDR-Lite","purl":"pkg:rpm/suse/perl-Net-CIDR-Lite\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Development%20Tools%2015%20SP5","source":"SUSE-SU-2024:1256-1"},{"ecosystem":"openSUSE:Leap 15.5","fixed":["0.21-150100.6.3.1"],"introduced":["0"],"last_affected":[],"package":"perl-Net-CIDR-Lite","purl":"pkg:rpm/opensuse/perl-Net-CIDR-Lite\u0026distro=openSUSE%20Leap%2015.5","source":"SUSE-SU-2024:1256-1"}],"prev":{"headline":"i2c: i801: Don't generate an interrupt on bus reset","id":"CVE-2021-47153"},"products":["n/a"],"published":"2024-03-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-15","vendors":["n/a"]},"summary":"Attackers can bypass IP-based access controls by using leading zeros in IP addresses, affecting applications using the Perl Net::CIDR::Lite module.","url":"https://insights.sbomify.com/CVE-2021-47154/"}
