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-2020-16157 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-16157/ (Markdown: https://insights.sbomify.com/CVE-2020-16157/index.md)","id":"CVE-2020-16157","markdown":"https://insights.sbomify.com/CVE-2020-16157/index.md","name":"CVE-2020-16157","record":{"aliases":["GHSA-9cr7-wpqj-r957"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Nagios Log Server","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts via the Email Users menu, potentially stealing sessions or executing code in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"log_server","vendor":"nagios"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A Stored XSS vulnerability exists in Nagios Log Server before 2.1.7 via the Notification Methods -\u003e Email Users menu.","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":"Cross-site scripting in n/a","id":"CVE-2020-16157","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-16158"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2020-16156"},"products":["n/a"],"published":"2020-07-30","related":[{"cvss_score":9.9,"headline":"Information disclosure in Log Server","id":"CVE-2025-44823","kev_date_added":null,"published":"2025-10-07"},{"cvss_score":9.4,"headline":"Nagios Log Server \u003c 2024R1.3.1 RCE via Malformed Dashboard ID","id":"CVE-2025-34277","kev_date_added":null,"published":"2025-10-30"},{"cvss_score":9.3,"headline":"Nagios Log Server \u003c 2024R2.0.3 Logstash Process Root Privileges","id":"CVE-2025-34274","kev_date_added":null,"published":"2025-10-30"},{"cvss_score":8.7,"headline":"Nagios Log Server \u003c 2024R1 Incorrect Authorization Granting Full API Access","id":"CVE-2023-7322","kev_date_added":null,"published":"2025-10-30"},{"cvss_score":8.7,"headline":"Nagios Log Server \u003c 2024R2.0.2 Cluster Manager Credential Requests Sent Over Plaintext","id":"CVE-2025-34271","kev_date_added":null,"published":"2025-10-30"},{"cvss_score":8.7,"headline":"Nagios Log Server \u003c 2024R1.3.2 Set Email Privilege Escalation","id":"CVE-2025-34298","kev_date_added":null,"published":"2025-10-30"},{"cvss_score":8.6,"headline":"Nagios Log Server \u003c 2026R1.0.1 Authenticated Command Injection via Natural Language Queries","id":"CVE-2025-34322","kev_date_added":null,"published":"2025-11-17"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject malicious scripts via the Email Users menu, potentially stealing sessions or executing code in victim browsers.","url":"https://insights.sbomify.com/CVE-2020-16157/"}
