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-2021-34724 in the wild and no public exploit code.\n\nAffected product: Cisco IOS XE SD-WAN Software. 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-2021-34724/ (Markdown: https://insights.sbomify.com/CVE-2021-34724/index.md)","id":"CVE-2021-34724","markdown":"https://insights.sbomify.com/CVE-2021-34724/index.md","name":"CVE-2021-34724","record":{"aliases":["GHSA-3jmx-8q3h-p8gc"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco SD-WAN Software","requires_auth":"high_privilege","summary":"Authenticated local attackers can overwrite installer files to execute arbitrary code as root on Cisco IOS XE SD-WAN devices.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xe_sd-wan","vendor":"cisco"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability in the Cisco IOS XE SD-WAN Software CLI could allow an authenticated, local attacker to elevate privileges and execute arbitrary code on the underlying operating system as the root user. An attacker must be authenticated on an affected device as a PRIV15 user. This vulnerability is due to insufficient file system protection and the presence of a sensitive file in the bootflash directory on an affected device. An attacker could exploit this vulnerability by overwriting an installer file stored in the bootflash directory with arbitrary commands that can be executed with root-level privileges. A successful exploit could allow the attacker to read and write changes to the configuration database on the affected 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 XE SD-WAN Software Privilege Escalation Vulnerability","id":"CVE-2021-34724","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOS XE SD-WAN Software Command Injection Vulnerability","id":"CVE-2021-34725"},"packages":[],"prev":{"headline":"Cisco IOS XE SD-WAN Software Arbitrary File Overwrite Vulnerability","id":"CVE-2021-34723"},"products":["Cisco IOS XE SD-WAN Software"],"published":"2021-09-23","related":[{"cvss_score":9.8,"headline":"Cisco IOS XE SD-WAN Software Buffer Overflow Vulnerability","id":"CVE-2021-34727","kev_date_added":null,"published":"2021-09-23"},{"cvss_score":9.8,"headline":"Cisco SD-WAN Solution Software Buffer Overflow Vulnerability","id":"CVE-2020-3375","kev_date_added":null,"published":"2020-07-31"},{"cvss_score":8.8,"headline":"Cisco SD-WAN vManage Authorization Bypass Vulnerabilities","id":"CVE-2021-1305","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":7.8,"headline":"Cisco IOS XE SD-WAN Software Command Injection Vulnerability","id":"CVE-2023-20035","kev_date_added":null,"published":"2023-03-23"},{"cvss_score":6.8,"headline":"Cisco IOS XE SD-WAN Software Authentication Bypass Vulnerability","id":"CVE-2020-3216","kev_date_added":null,"published":"2020-06-03"},{"cvss_score":6.7,"headline":"Cisco IOS XE SD-WAN Software Command Injection Vulnerability","id":"CVE-2021-34725","kev_date_added":null,"published":"2021-09-23"},{"cvss_score":6.6,"headline":"Cisco IOS XE SD-WAN Software Console Privilege Escalation Vulnerability","id":"CVE-2021-1371","kev_date_added":null,"published":"2021-03-24"}],"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":"2024-11-07","vendors":["Cisco"]},"summary":"Authenticated local attackers can overwrite installer files to execute arbitrary code as root on Cisco IOS XE SD-WAN devices.","url":"https://insights.sbomify.com/CVE-2021-34724/"}
