Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-15956 in the wild and no public exploit code.\n\nAffected product: Cisco Asyncos. 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-2019-15956/ (Markdown: https://insights.sbomify.com/CVE-2019-15956/index.md)","id":"CVE-2019-15956","markdown":"https://insights.sbomify.com/CVE-2019-15956/index.md","name":"CVE-2019-15956","record":{"aliases":["GHSA-8pmp-qg97-8gmp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Web Security Appliance","requires_auth":"low_privilege","summary":"Authenticated attackers can bypass authorization to reset the device, gaining admin access or causing denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"asyncos","vendor":"cisco"},{"product":"web_security_appliance","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability in the web management interface of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform an unauthorized system reset on an affected device. The vulnerability is due to improper authorization controls for a specific URL in the web management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could have a twofold impact: the attacker could either change the administrator password, gaining privileged access, or reset the network configuration details, causing a denial of service (DoS) condition. In both scenarios, manual intervention is required to restore normal operations.","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 Web Security Appliance Unauthorized Device Reset Vulnerability","id":"CVE-2019-15956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:asyncos","products":["cisco:asyncos","cisco:web_security_appliance"],"type":"missing_authorization","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Small Business Routers RV016, RV042, RV042G, RV082, RV320, and RV325 Command Injection Vulnerability","id":"CVE-2019-15957"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2019-15955"},"products":["Cisco Web Security Appliance (WSA)"],"published":"2019-11-26","related":[{"cvss_score":10,"headline":"Cisco Multiple Products Improper Input Validation","id":"CVE-2025-20393","kev_date_added":"2025-12-17","published":"2025-12-17"},{"cvss_score":9.8,"headline":"Cisco Secure Email Gateway Relative Path Traversal","id":"CVE-2026-76519","kev_date_added":"2026-10-14","published":"2026-10-14"},{"cvss_score":9.8,"headline":"Cisco Secure Email Gateway SQL Injection","id":"CVE-2026-76461","kev_date_added":"2026-09-14","published":"2026-09-14"},{"cvss_score":8.8,"headline":"Command injection in Cisco Secure Web Appliance","id":"CVE-2024-20435","kev_date_added":null,"published":"2024-07-17"},{"cvss_score":8.6,"headline":"Cisco Web Security Appliance Proxy Service Denial of Service Vulnerability","id":"CVE-2021-34698","kev_date_added":null,"published":"2021-10-06"},{"cvss_score":8.6,"headline":"Cisco Email Security Appliance Denial of Service Vulnerability","id":"CVE-2019-1947","kev_date_added":null,"published":"2020-09-23"}],"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":"2024-11-20","vendors":["Cisco"]},"summary":"Authenticated attackers can bypass authorization to reset the device, gaining admin access or causing denial of service.","url":"https://insights.sbomify.com/CVE-2019-15956/"}
