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-2023-20064 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xr. 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-2023-20064/ (Markdown: https://insights.sbomify.com/CVE-2023-20064/index.md)","id":"CVE-2023-20064","markdown":"https://insights.sbomify.com/CVE-2023-20064/index.md","name":"CVE-2023-20064","record":{"aliases":["GHSA-8vc7-mgh3-xppf"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IOS XR","requires_auth":"none","summary":"An attacker with physical access can view sensitive files via GRUB bootloader commands during power cycling, potentially aiding further attacks.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xr","vendor":"cisco"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A vulnerability in the GRand Unified Bootloader (GRUB) for Cisco IOS XR Software could allow an unauthenticated attacker with physical access to the device to view sensitive files on the console using the GRUB bootloader command line. This vulnerability is due to the inclusion of unnecessary commands within the GRUB environment that allow sensitive files to be viewed. An attacker could exploit this vulnerability by being connected to the console port of the Cisco IOS XR device when the device is power-cycled. A successful exploit could allow the attacker to view sensitive files that could be used to conduct additional attacks against the device.","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":"Cisco IOS XR Software Bootloader Unauthenticated Information Disclosure Vulnerability","id":"CVE-2023-20064","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios_xr","products":["cisco:ios_xr"],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Cisco IOS XE Software","id":"CVE-2023-20065"},"packages":[],"prev":{"headline":"Cisco Cisco Firepower Threat Defense Software and Cisco Firepower Management Center Code Injection Vulnerability","id":"CVE-2023-20063"},"products":["Cisco IOS XR Software"],"published":"2023-03-09","related":[{"cvss_score":8.8,"headline":"Cisco IOS XR Software Discovery Protocol Format String","id":"CVE-2020-3118","kev_date_added":"2021-11-03","published":"2020-02-05"},{"cvss_score":8.6,"headline":"Cisco IOS XR Software DVMRP Memory Exhaustion","id":"CVE-2020-3569","kev_date_added":"2021-11-03","published":"2020-09-23"},{"cvss_score":8.6,"headline":"Cisco IOS XR Software DVMRP Memory Exhaustion","id":"CVE-2020-3566","kev_date_added":"2021-11-03","published":"2020-08-29"},{"cvss_score":7.5,"headline":"Cisco IOS XR Border Gateway Protocol (BGP) Denial-of-Service","id":"CVE-2010-3035","kev_date_added":"2022-03-25","published":"2010-08-30"},{"cvss_score":6.5,"headline":"Cisco IOS XR Open Port","id":"CVE-2022-20821","kev_date_added":"2022-05-23","published":"2022-05-26"},{"cvss_score":5.9,"headline":"Cisco IOS XR Border Gateway Protocol (BGP) Denial-of-Service","id":"CVE-2009-2055","kev_date_added":"2022-03-25","published":"2009-08-19"},{"cvss_score":9.8,"headline":"Cisco IOS XR Software Security Hardening Release: September 2026","id":"CVE-2026-20274","kev_date_added":null,"published":"2026-09-02"}],"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":"partial"},"state":"PUBLISHED","updated":"2024-10-25","vendors":["Cisco"]},"summary":"An attacker with physical access can view sensitive files via GRUB bootloader commands during power cycling, potentially aiding further attacks.","url":"https://insights.sbomify.com/CVE-2023-20064/"}
