An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-1943 exists.\n\nAffected product: Cisco Small Business 300 Series Managed Switches. 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-2019-1943/ (Markdown: https://insights.sbomify.com/CVE-2019-1943/index.md)","id":"CVE-2019-1943","markdown":"https://insights.sbomify.com/CVE-2019-1943/index.md","name":"CVE-2019-1943","record":{"aliases":["GHSA-c4p7-9fgh-g95m"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Small Business Switch","requires_auth":"none","summary":"An unauthenticated remote attacker can redirect users to malicious sites via the web interface, facilitating phishing attacks on Cisco Small Business Switches.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"sf200-24_firmware","vendor":"cisco"},{"product":"sf200-24fp_firmware","vendor":"cisco"},{"product":"sf200-24p_firmware","vendor":"cisco"},{"product":"sf200-48_firmware","vendor":"cisco"},{"product":"sf200-48p_firmware","vendor":"cisco"},{"product":"sf300-08_firmware","vendor":"cisco"},{"product":"sf300-24_firmware","vendor":"cisco"},{"product":"sf300-24mp_firmware","vendor":"cisco"},{"product":"sf300-24p_firmware","vendor":"cisco"},{"product":"sf300-24pp_firmware","vendor":"cisco"},{"product":"sf300-48_firmware","vendor":"cisco"},{"product":"sf300-48p_firmware","vendor":"cisco"},{"product":"sf300-48pp_firmware","vendor":"cisco"},{"product":"sf302-08_firmware","vendor":"cisco"},{"product":"sf302-08mp_firmware","vendor":"cisco"},{"product":"sf302-08mpp_firmware","vendor":"cisco"},{"product":"sf302-08p_firmware","vendor":"cisco"},{"product":"sf302-08pp_firmware","vendor":"cisco"},{"product":"sf500-24_firmware","vendor":"cisco"},{"product":"sf500-24p_firmware","vendor":"cisco"},{"product":"sf500-48_firmware","vendor":"cisco"},{"product":"sf500-48p_firmware","vendor":"cisco"},{"product":"sg200-08_firmware","vendor":"cisco"},{"product":"sg200-08p_firmware","vendor":"cisco"},{"product":"sg200-10fp_firmware","vendor":"cisco"},{"product":"sg200-18_firmware","vendor":"cisco"},{"product":"sg200-26_firmware","vendor":"cisco"},{"product":"sg200-26fp_firmware","vendor":"cisco"},{"product":"sg200-26p_firmware","vendor":"cisco"},{"product":"sg200-50_firmware","vendor":"cisco"},{"product":"sg200-50fp_firmware","vendor":"cisco"},{"product":"sg200-50p_firmware","vendor":"cisco"},{"product":"sg300-10_firmware","vendor":"cisco"},{"product":"sg300-10mp_firmware","vendor":"cisco"},{"product":"sg300-10mpp_firmware","vendor":"cisco"},{"product":"sg300-10p_firmware","vendor":"cisco"},{"product":"sg300-10pp_firmware","vendor":"cisco"},{"product":"sg300-10sfp_firmware","vendor":"cisco"},{"product":"sg300-20_firmware","vendor":"cisco"},{"product":"sg300-28_firmware","vendor":"cisco"},{"product":"sg300-28mp_firmware","vendor":"cisco"},{"product":"sg300-28p_firmware","vendor":"cisco"},{"product":"sg300-28pp_firmware","vendor":"cisco"},{"product":"sg300-52_firmware","vendor":"cisco"},{"product":"sg300-52mp_firmware","vendor":"cisco"},{"product":"sg300-52p_firmware","vendor":"cisco"},{"product":"sg500-28_firmware","vendor":"cisco"},{"product":"sg500-28mpp_firmware","vendor":"cisco"},{"product":"sg500-28p_firmware","vendor":"cisco"},{"product":"sg500-52_firmware","vendor":"cisco"},{"product":"sg500-52mp_firmware","vendor":"cisco"},{"product":"sg500-52p_firmware","vendor":"cisco"},{"product":"sg500x-24_firmware","vendor":"cisco"},{"product":"sg500x-24p_firmware","vendor":"cisco"},{"product":"sg500x-48_firmware","vendor":"cisco"},{"product":"sg500x-48p_firmware","vendor":"cisco"},{"product":"sg500xg-8f8t_firmware","vendor":"cisco"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"A vulnerability in the web interface of Cisco Small Business 200, 300, and 500 Series Switches software could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user's HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2019-07-15","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":"2019-07-15","kind":"exploitdb","ref":"47118","stars":null,"title":"CISCO Small Business 200 / 300 / 500 Switches - Multiple Vulnerabilities"},{"date":null,"kind":"nuclei","ref":"http/cves/2019/CVE-2019-1943.yaml","stars":null,"title":"Cisco Small Business 200,300 and 500 Series Switches - Open Redirect"}],"tier":"weaponised"},"has_fix":null,"headline":"Cisco Small Business Series Switches Open Redirect Vulnerability","id":"CVE-2019-1943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Adaptive Security Appliance Smart Tunnel Vulnerabilities","id":"CVE-2019-1944"},"packages":[],"prev":{"headline":"Cisco Identity Services Engine Blind SQL Injection Vulnerability","id":"CVE-2019-1942"},"products":["Cisco Small Business 300 Series Managed Switches"],"published":"2019-07-17","related":[{"cvss_score":9.8,"headline":"Cisco Small Business Switches Privileged Access Vulnerability","id":"CVE-2018-15439","kev_date_added":null,"published":"2018-11-08"},{"cvss_score":8.6,"headline":"Cisco Small Business Smart and Managed Switches Denial of Service Vulnerability","id":"CVE-2020-3363","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":8.1,"headline":"Cisco Small Business Smart and Managed Switches Session Management Vulnerability","id":"CVE-2020-3297","kev_date_added":null,"published":"2020-07-02"},{"cvss_score":8.1,"headline":"Cisco Small Business Smart and Managed Switches Cross-Site Request Forgery Vulnerability","id":"CVE-2019-12636","kev_date_added":null,"published":"2019-10-16"},{"cvss_score":7.5,"headline":"Cisco Small Business Switches Information Disclosure Vulnerability","id":"CVE-2019-15993","kev_date_added":null,"published":"2020-09-23"},{"cvss_score":7.2,"headline":"Cisco Small Business Switches Secure Shell Certificate Authentication Bypass Vulnerability","id":"CVE-2019-1859","kev_date_added":null,"published":"2019-05-03"},{"cvss_score":6.1,"headline":"Cisco Small Business Smart and Managed Switches Cross-Site Scripting Vulnerability","id":"CVE-2019-12718","kev_date_added":null,"published":"2019-10-16"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-21","vendors":["Cisco"]},"summary":"An unauthenticated remote attacker can redirect users to malicious sites via the web interface, facilitating phishing attacks on Cisco Small Business Switches.","url":"https://insights.sbomify.com/CVE-2019-1943/"}
