An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-20923 in the wild and no public exploit code.\n\nAffected product: Cisco Rv110w Firmware. 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-2022-20923/ (Markdown: https://insights.sbomify.com/CVE-2022-20923/index.md)","id":"CVE-2022-20923","markdown":"https://insights.sbomify.com/CVE-2022-20923/index.md","name":"CVE-2022-20923","record":{"aliases":["GHSA-q55q-mwv4-x93q"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Small Business Router","requires_auth":"none","summary":"Unauthenticated remote attackers can bypass IPSec VPN authentication on Cisco Small Business Routers to gain administrative-level network access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"rv110w_firmware","vendor":"cisco"},{"product":"rv130_firmware","vendor":"cisco"},{"product":"rv130w_firmware","vendor":"cisco"},{"product":"rv215w_firmware","vendor":"cisco"}],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-303","name":"Incorrect Implementation of Authentication Algorithm"}],"description":"A vulnerability in the IPSec VPN Server authentication functionality of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an unauthenticated, remote attacker to bypass authentication controls and access the IPSec VPN network. This vulnerability is due to the improper implementation of the password validation algorithm. An attacker could exploit this vulnerability by logging in to the VPN from an affected device with crafted credentials. A successful exploit could allow the attacker to bypass authentication and access the IPSec VPN network. The attacker may obtain privileges that are the same level as an administrative user, depending on the crafted credentials that are used. Cisco has not released software updates that address this vulnerability.","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 Small Business RV110W, RV130, RV130W, and RV215W Routers IPSec VPN Server Authentication Bypass Vulnerability","id":"CVE-2022-20923","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:rv110w_firmware","products":["cisco:rv110w_firmware","cisco:rv130_firmware","cisco:rv130w_firmware","cisco:rv215w_firmware"],"type":"auth_bypass","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2022-20924"},"packages":[],"prev":{"headline":"Denial of service in Cisco Cyber Vision","id":"CVE-2022-20922"},"products":["Cisco Small Business RV Series Router Firmware"],"published":"2022-09-08","related":[{"cvss_score":9.8,"headline":"Command injection in Cisco Small Business RV Series Router Firmware","id":"CVE-2022-20825","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":9.8,"headline":"Command injection in Cisco Small Business RV Series Router Firmware","id":"CVE-2021-1459","kev_date_added":null,"published":"2021-04-08"},{"cvss_score":9.8,"headline":"Cisco RV110W, RV130, RV130W, and RV215W Routers Authentication Bypass Vulnerability","id":"CVE-2020-3144","kev_date_added":null,"published":"2020-07-16"},{"cvss_score":9.8,"headline":"Cisco RV110W, RV130W, and RV215W Routers Management Interface Remote Command Execution Vulnerability","id":"CVE-2019-1663","kev_date_added":null,"published":"2019-02-28"},{"cvss_score":9.8,"headline":"Cisco RV110W, RV130W, and RV215W Routers Management Interface Information Disclosure Vulnerability","id":"CVE-2018-0425","kev_date_added":null,"published":"2018-10-05"},{"cvss_score":9.8,"headline":"Cisco RV110W, RV130W, and RV215W Routers Management Interface Directory Traversal Vulnerability","id":"CVE-2018-0426","kev_date_added":null,"published":"2018-10-05"},{"cvss_score":8.8,"headline":"Cisco RV110W, RV130, RV130W, and RV215W Routers Management Interface Remote Command Execution Multiple Vulnerabilities","id":"CVE-2020-3145","kev_date_added":null,"published":"2020-07-16"}],"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":"2024-11-06","vendors":["Cisco"]},"summary":"Unauthenticated remote attackers can bypass IPSec VPN authentication on Cisco Small Business Routers to gain administrative-level network access.","url":"https://insights.sbomify.com/CVE-2022-20923/"}
