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-2008-4930 in the wild and no public exploit code.\n\nAffected product: Mybb Mybb. 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-2008-4930/ (Markdown: https://insights.sbomify.com/CVE-2008-4930/index.md)","id":"CVE-2008-4930","markdown":"https://insights.sbomify.com/CVE-2008-4930/index.md","name":"CVE-2008-4930","record":{"aliases":["GHSA-m5jh-9fcq-22hm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MyBB forum software","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary scripts in victims' browsers via malicious file uploads, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mybb","vendor":"mybb"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"MyBB (aka MyBulletinBoard) 1.4.2 does not properly handle an uploaded file with a nonstandard file type that contains HTML sequences, which allows remote attackers to cause that file to be processed as HTML by Internet Explorer's content inspection, aka \"Incomplete protection against MIME-sniffing.\" NOTE: this could be leveraged for XSS and other attacks.","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-2008-4930","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mybb:mybb","products":["mybb:mybb"],"type":"xss","year":"2008"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2008-4931"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2008-4929"},"products":["n/a"],"published":"2008-11-04","related":[{"cvss_score":10,"headline":"myBB 1.6.4 Backdoor Arbitrary Command Execution","id":"CVE-2011-10018","kev_date_added":null,"published":"2025-08-13"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2015-2786","kev_date_added":null,"published":"2015-03-29"},{"cvss_score":10,"headline":"Cross-site scripting in n/a","id":"CVE-2011-5133","kev_date_added":null,"published":"2012-08-30"},{"cvss_score":10,"headline":"SQL injection in n/a","id":"CVE-2006-0218","kev_date_added":null,"published":"2006-01-16"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-22612","kev_date_added":null,"published":"2023-09-01"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2017-16780","kev_date_added":null,"published":"2017-11-10"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2021-27890","kev_date_added":null,"published":"2021-03-15"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary scripts in victims' browsers via malicious file uploads, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2008-4930/"}
