It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-47039 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 6. 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-2023-47039/ (Markdown: https://insights.sbomify.com/CVE-2023-47039/index.md)","id":"CVE-2023-47039","markdown":"https://insights.sbomify.com/CVE-2023-47039/index.md","name":"CVE-2023-47039","record":{"aliases":["GHSA-44qm-928x-6p3g","UBUNTU-CVE-2023-47039"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl interpreter","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code with administrator privileges by placing a malicious cmd.exe in the current working directory due to insecure path search order.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"perl","vendor":"perl"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability was found in Perl. This security issue occurs while Perl for Windows relies on the system path environment variable to find the shell (`cmd.exe`). When running an executable that uses the Windows Perl interpreter, Perl attempts to find and execute `cmd.exe` within the operating system. However, due to path search order issues, Perl initially looks for cmd.exe in the current working directory. This flaw allows an attacker with limited privileges to place`cmd.exe` in locations with weak permissions, such as `C:\\ProgramData`. By doing so, arbitrary code can be executed when an administrator attempts to use this executable from these compromised locations.","ecosystems":[],"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":"Perl: perl for windows binary hijacking vulnerability","id":"CVE-2023-47039","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"ZDI-CAN-21698: Adobe Media Encoder MP4 File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability","id":"CVE-2023-47040"},"packages":[],"prev":{"headline":"Perl: write past buffer end via illegal user-defined unicode property","id":"CVE-2023-47038"},"products":["Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9"],"published":"2024-01-02","related":[{"cvss_score":9.8,"headline":"Supply chain in perl","id":"CVE-2026-4176","kev_date_added":null,"published":"2026-03-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-48522","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12814","kev_date_added":null,"published":"2017-09-27"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2015-8608","kev_date_added":null,"published":"2017-02-07"},{"cvss_score":9.1,"headline":"Integer overflow in perl:perl","id":"CVE-2026-13221","kev_date_added":null,"published":"2026-07-13"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2017-12883","kev_date_added":null,"published":"2017-09-19"},{"cvss_score":8.4,"headline":"Integer overflow in perl:perl","id":"CVE-2026-57432","kev_date_added":null,"published":"2026-07-13"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-11-20","vendors":["Red Hat"]},"summary":"An attacker can execute arbitrary code with administrator privileges by placing a malicious cmd.exe in the current working directory due to insecure path search order.","url":"https://insights.sbomify.com/CVE-2023-47039/"}
