An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-40891 in the wild and no public exploit code.\n\nAffected product: Nozomi Networks CMC. 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-2025-40891/ (Markdown: https://insights.sbomify.com/CVE-2025-40891/index.md)","id":"CVE-2025-40891","markdown":"https://insights.sbomify.com/CVE-2025-40891/index.md","name":"CVE-2025-40891","record":{"aliases":["GHSA-q3xp-m695-72w5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Nozomi Networks CMC","requires_auth":"none","summary":"Unauthenticated attackers can inject HTML into snapshot attributes, enabling phishing and open redirects when victims view specific diffs in the Time Machine feature.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[{"product":"cmc","vendor":"nozominetworks"},{"product":"guardian","vendor":"nozominetworks"}],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A Stored HTML Injection vulnerability was discovered in the Time Machine Snapshot Diff functionality due to improper validation of network traffic data. An unauthenticated attacker can send specially crafted network packets at two different times to inject HTML tags into asset attributes across two snapshots. Exploitation requires a victim to use the Time Machine Snapshot Diff feature on those specific snapshots and perform specific GUI actions, at which point the injected HTML renders in their browser, enabling phishing and open redirect attacks. Full XSS exploitation is prevented by input validation and Content Security Policy. Attack complexity is high due to multiple required conditions.","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":"HTML injection in in Time Machine functionality in Guardian/CMC before 25.5.0","id":"CVE-2025-40891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Stored Cross-Site Scripting (XSS) in Reports in Guardian/CMC before 25.5.0","id":"CVE-2025-40892"},"packages":[],"prev":{"headline":"Stored Cross-Site Scripting (XSS) in Dashboards in Guardian/CMC before 25.4.0","id":"CVE-2025-40890"},"products":["CMC","Guardian"],"published":"2025-12-18","related":[{"cvss_score":9.2,"headline":"SQL Injection on IDS parsing of malformed asset fields in Guardian/CMC \u003e= 22.6.0 before 22.6.3 and 23.1.0","id":"CVE-2023-29245","kev_date_added":null,"published":"2023-09-19"},{"cvss_score":8.7,"headline":"DoS through oversized audit log entries in Guardian/CMC before 26.2.0","id":"CVE-2026-31984","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":8.7,"headline":"Authenticated SQL Injection on Query functionality in Guardian/CMC before 22.6.3 and 23.1.0","id":"CVE-2023-2567","kev_date_added":null,"published":"2023-09-19"},{"cvss_score":8.7,"headline":"Authenticated Blind SQL Injection on sorting in Guardian/CMC before 22.6.2","id":"CVE-2023-22378","kev_date_added":null,"published":"2023-08-09"},{"cvss_score":8.7,"headline":"Authenticated Blind SQL Injection on alerts count in Guardian/CMC before 22.6.2","id":"CVE-2023-23574","kev_date_added":null,"published":"2023-08-09"},{"cvss_score":8.7,"headline":"Authenticated SQL Injection on Alerts in Guardian/CMC before 22.5.2","id":"CVE-2022-4259","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":8.6,"headline":"Authenticated RCE on logo report upload in Guardian/CMC before 22.0.0","id":"CVE-2022-0550","kev_date_added":null,"published":"2022-03-24"}],"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":"2026-08-11","vendors":["Nozomi Networks"]},"summary":"Unauthenticated attackers can inject HTML into snapshot attributes, enabling phishing and open redirects when victims view specific diffs in the Time Machine feature.","url":"https://insights.sbomify.com/CVE-2025-40891/"}
