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-2023-3521 exists.\n\nAffected product: fossbilling/fossbilling. 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-2023-3521/ (Markdown: https://insights.sbomify.com/CVE-2023-3521/index.md)","id":"CVE-2023-3521","markdown":"https://insights.sbomify.com/CVE-2023-3521/index.md","name":"CVE-2023-3521","record":{"aliases":["GHSA-f2hf-p7mp-7x9v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"FOSSBilling web application","requires_auth":"none","summary":"Reflected Cross-Site Scripting in FOSSBilling allows attackers to execute arbitrary scripts in victim browsers, potentially leading to session hijacking or data theft.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"fossbilling","vendor":"fossbilling"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site Scripting (XSS) - Reflected in GitHub repository fossbilling/fossbilling prior to 0.5.4.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-3521.yaml","stars":null,"title":"FOSSBilling \u003c 0.5.3 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":false,"headline":"Cross-site Scripting (XSS) - Reflected in fossbilling/fossbilling","id":"CVE-2023-3521","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"SQLi in a2 License Portal System","id":"CVE-2023-3522"},"packages":[],"prev":{"headline":"Sensitive Cookie in HTTPS Session Without 'Secure' Attribute in it-novum/openitcockpit","id":"CVE-2023-3520"},"products":["fossbilling/fossbilling"],"published":"2023-07-06","related":[{"cvss_score":9.8,"headline":"SQL Injection in fossbilling/fossbilling","id":"CVE-2023-3490","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":8,"headline":"Unrestricted Upload of File with Dangerous Type in fossbilling/fossbilling","id":"CVE-2023-3491","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":8,"headline":"Code Injection in fossbilling/fossbilling","id":"CVE-2023-3393","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":7.7,"headline":"Improper Neutralization of Formula Elements in a CSV File in fossbilling/fossbilling","id":"CVE-2023-3493","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":6.8,"headline":"Session Fixation in fossbilling/fossbilling","id":"CVE-2023-3394","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":6.3,"headline":"Open Redirect in alextselegidis/easyappointments","id":"CVE-2023-3568","kev_date_added":null,"published":"2023-07-10"}],"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":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-31","vendors":["fossbilling"]},"summary":"Reflected Cross-Site Scripting in FOSSBilling allows attackers to execute arbitrary scripts in victim browsers, potentially leading to session hijacking or data theft.","url":"https://insights.sbomify.com/CVE-2023-3521/"}
