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-2021-29923 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected all versions; fixed in 1.17.0\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-2021-29923/ (Markdown: https://insights.sbomify.com/CVE-2021-29923/index.md)","id":"CVE-2021-29923","markdown":"https://insights.sbomify.com/CVE-2021-29923/index.md","name":"CVE-2021-29923","record":{"aliases":["AZL-79056","AZL-98910","BIT-golang-2021-29923","DEBIAN-CVE-2021-29923","GHSA-38h6-vxp4-qxvm","RHSA-2021:3585","RHSA-2021:4910","RHSA-2022:0989","RHSA-2022:0997","RLSA-2021:3585","UBUNTU-CVE-2021-29923"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"Attackers can bypass IP-based access controls by using leading zeros in IP addresses, affecting Go applications using net.ParseIP or net.ParseCIDR.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"go","vendor":"golang"},{"product":"timesten_in-memory_database","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation.
