Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-3157 in the wild and no public exploit code.\n\nAffected product: Cisco Identity Services Engine. 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-2020-3157/ (Markdown: https://insights.sbomify.com/CVE-2020-3157/index.md)","id":"CVE-2020-3157","markdown":"https://insights.sbomify.com/CVE-2020-3157/index.md","name":"CVE-2020-3157","record":{"aliases":["GHSA-5473-pqp3-92vj"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Identity Services Engine","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious scripts into the Cisco ISE web interface, potentially executing code or stealing data when administrators view configurations.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"identity_services_engine","vendor":"cisco"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. The vulnerability is due to insufficient validation of user-supplied input to the web-based management interface. An attacker could exploit this vulnerability by crafting a malicious configuration and saving it to the targeted system. An exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information when an administrator views the configuration. An attacker would need write permissions to exploit this vulnerability successfully.","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 Identity Services Engine Cross-Site Scripting Vulnerability","id":"CVE-2020-3157","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:identity_services_engine","products":["cisco:identity_services_engine"],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Smart Software Manager On-Prem Static Default Credential Vulnerability","id":"CVE-2020-3158"},"packages":[],"prev":{"headline":"Cisco Identity Services Engine Cross-Site Scripting Vulnerability","id":"CVE-2020-3156"},"products":["Cisco Identity Services Engine Software"],"published":"2020-03-04","related":[{"cvss_score":10,"headline":"Cisco Identity Services Engine Incorrect Use of Privileged APIs","id":"CVE-2026-76460","kev_date_added":"2026-09-16","published":"2026-09-16"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Injection","id":"CVE-2025-20337","kev_date_added":"2025-07-28","published":"2025-07-16"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Injection","id":"CVE-2025-20281","kev_date_added":"2025-07-28","published":"2025-06-25"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Hardening Release - Improper Neutralization Vulnerabilities","id":"CVE-2026-20130","kev_date_added":null,"published":"2026-09-16"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Hardening Release - Access Control Vulnerabilities","id":"CVE-2026-20192","kev_date_added":null,"published":"2026-09-16"},{"cvss_score":10,"headline":"Cisco ISE API Unauthenticated Remote Code Execution Vulnerability","id":"CVE-2025-20282","kev_date_added":null,"published":"2025-06-25"},{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2011-3290","kev_date_added":null,"published":"2011-09-21"}],"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":"2024-11-15","vendors":["Cisco"]},"summary":"Authenticated attackers can inject malicious scripts into the Cisco ISE web interface, potentially executing code or stealing data when administrators view configurations.","url":"https://insights.sbomify.com/CVE-2020-3157/"}
