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-2025-40910 in the wild and no public exploit code.\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-2025-40910/ (Markdown: https://insights.sbomify.com/CVE-2025-40910/index.md)","id":"CVE-2025-40910","markdown":"https://insights.sbomify.com/CVE-2025-40910/index.md","name":"CVE-2025-40910","record":{"aliases":["GHSA-7ffq-hwvw-j35c"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl IP library","requires_auth":"none","summary":"Attackers can bypass IP-based access controls by using leading zeros in CIDR strings, confusing octal and decimal parsing in the Net::IP::LPM Perl library.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"Net::IP::LPM version 1.10 for Perl does not properly consider leading zero characters in IP CIDR address strings, which could allow attackers to bypass access control that is based on IP addresses.\n\nLeading zeros are used to indicate octal numbers, which can confuse users who are intentionally using octal notation, as well as users who believe they are using decimal notation.","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":"Net::IP::LPM version 1.10 for Perl does not properly consider leading zero characters in IP CIDR address strings, which could allow attacker","id":"CVE-2025-40910","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"Security feature bypass in Net::CIDR::Set","id":"CVE-2025-40911"},"packages":[],"prev":{"headline":"Perl threads have a working directory race condition where file operations may target unintended paths","id":"CVE-2025-40909"},"products":[],"published":"2025-06-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-07","vendors":[]},"summary":"Attackers can bypass IP-based access controls by using leading zeros in CIDR strings, confusing octal and decimal parsing in the Net::IP::LPM Perl library.","url":"https://insights.sbomify.com/CVE-2025-40910/"}
