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-2023-45556 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mybb (Bitnami): affected all versions; fixed in 1.8.37\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-2023-45556/ (Markdown: https://insights.sbomify.com/CVE-2023-45556/index.md)","id":"CVE-2023-45556","markdown":"https://insights.sbomify.com/CVE-2023-45556/index.md","name":"CVE-2023-45556","record":{"aliases":["BIT-mybb-2023-45556"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MyBB forum software","requires_auth":"low_privilege","summary":"A local attacker can execute arbitrary code via the theme Name parameter in MyBB Forums, requiring an upgrade to mitigate.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mybb","vendor":"mybb"}],"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":"Cross Site Scripting vulnerability in Mybb Mybb Forums v.1.8.33 allows a local attacker to execute arbitrary code via the theme Name parameter in the theme management component.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cross-site scripting in n/a","id":"CVE-2023-45556","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mybb:mybb","products":["mybb:mybb"],"type":"xss","year":"2023"},"n_packages":1,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2023-45558"},"packages":[{"ecosystem":"Bitnami","fixed":["1.8.37"],"introduced":["0"],"last_affected":[],"package":"mybb","purl":"pkg:bitnami/mybb","source":"BIT-mybb-2023-45556"}],"prev":{"headline":"File upload in n/a","id":"CVE-2023-45555"},"products":["n/a"],"published":"2023-11-06","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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2024-09-05","vendors":["n/a"]},"summary":"A local attacker can execute arbitrary code via the theme Name parameter in MyBB Forums, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2023-45556/"}
