An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-45423 exists.\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-2021-45423/ (Markdown: https://insights.sbomify.com/CVE-2021-45423/index.md)","id":"CVE-2021-45423","markdown":"https://insights.sbomify.com/CVE-2021-45423/index.md","name":"CVE-2021-45423","record":{"aliases":["DEBIAN-CVE-2021-45423","GHSA-4r8p-6r2m-cjwv","UBUNTU-CVE-2021-45423"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PEV binary analysis tool","requires_auth":"none","summary":"A buffer overflow in the Pev binary analysis tool allows arbitrary code execution via a crafted PE file due to incorrect array bounds checking.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pev","vendor":"pev_project"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A Buffer Overflow vulnerabilityexists in Pev 0.81 via the pe_exports function from exports.c..
