An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-2816 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/consul (Go): affected from 1.15.0; fixed in 1.15.3\n- github.com/hashicorp/consul (Go): affected from 1.15.0; fixed in 1.15.3\n- github.com/hashicorp/consul (Go): affected from 1.15.0; fixed in 1.15.3\n- consul (Bitnami): affected from 1.15.0; fixed in 1.15.3\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-2023-2816/ (Markdown: https://insights.sbomify.com/CVE-2023-2816/index.md)","id":"CVE-2023-2816","markdown":"https://insights.sbomify.com/CVE-2023-2816/index.md","name":"CVE-2023-2816","record":{"aliases":["AZL-27396","AZL-35303","BIT-consul-2023-2816","GHSA-rqjq-ww83-wv5c","GO-2023-1828","UBUNTU-CVE-2023-2816"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Service mesh software","requires_auth":"high_privilege","summary":"Users with service write permissions can modify remote proxy configurations for services they do not own, bypassing intended access controls.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[{"product":"consul","vendor":"hashicorp"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"Consul and Consul Enterprise allowed any user with service:write permissions to use Envoy extensions configured via service-defaults to patch remote proxy instances that target the configured service, regardless of whether the user has permission to modify the service(s) corresponding to those modified proxies.","ecosystems":["Bitnami","Go"],"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":"Consul Envoy Extension Downsteam Proxy Configuration By Upstream Service Owner","id":"CVE-2023-2816","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":4,"n_references":1,"next":{"headline":"Stored cross site scripting in Craft CMS","id":"CVE-2023-2817"},"packages":[{"ecosystem":"Bitnami","fixed":["1.15.3"],"introduced":["1.15.0"],"last_affected":[],"package":"consul","purl":"pkg:bitnami/consul","source":"BIT-consul-2023-2816"},{"ecosystem":"Go","fixed":["1.15.3"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/hashicorp/consul","purl":null,"source":"GHSA-rqjq-ww83-wv5c"},{"ecosystem":"Go","fixed":["1.15.3"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/hashicorp/consul","purl":"pkg:golang/github.com/hashicorp/consul","source":"GHSA-rqjq-ww83-wv5c"},{"ecosystem":"Go","fixed":["1.15.3"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/hashicorp/consul","purl":"pkg:golang/github.com/hashicorp/consul","source":"GO-2023-1828"}],"prev":{"headline":"SourceCodester Online Jewelry Store POST Parameter supplier.php sql injection","id":"CVE-2023-2815"},"products":["Consul","Consul Enterprise"],"published":"2023-06-02","related":[{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2021-41805","kev_date_added":null,"published":"2021-12-12"},{"cvss_score":8.8,"headline":"HashiCorp Consul Privilege Escalation Vulnerability","id":"CVE-2021-37219","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":8.3,"headline":"Consul L7 Intentions Vulnerable To Headers Bypass","id":"CVE-2024-10006","kev_date_added":null,"published":"2024-10-30"},{"cvss_score":8.1,"headline":"Consul L7 Intentions Vulnerable To URL Path Bypass","id":"CVE-2024-10005","kev_date_added":null,"published":"2024-10-30"},{"cvss_score":8.1,"headline":"HashiCorp Consul Access Restriction Bypass","id":"CVE-2019-8336","kev_date_added":null,"published":"2019-03-05"},{"cvss_score":7.5,"headline":"Hashicorp Consul Missing SSL Certificate Validation","id":"CVE-2021-32574","kev_date_added":null,"published":"2021-07-17"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2024-10-07","vendors":["HashiCorp"]},"summary":"Users with service write permissions can modify remote proxy configurations for services they do not own, bypassing intended access controls.","url":"https://insights.sbomify.com/CVE-2023-2816/"}
