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-2009-4142 exists.\n\nAffected product: Php Php. 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-2009-4142/ (Markdown: https://insights.sbomify.com/CVE-2009-4142/index.md)","id":"CVE-2009-4142","markdown":"https://insights.sbomify.com/CVE-2009-4142/index.md","name":"CVE-2009-4142","record":{"aliases":["GHSA-q555-wmm9-43g3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP scripting language","requires_auth":"none","summary":"Remote attackers can execute cross-site scripting attacks by exploiting improper handling of invalid character sequences in the PHP htmlspecialchars function.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The htmlspecialchars function in PHP before 5.2.12 does not properly handle (1) overlong UTF-8 sequences, (2) invalid Shift_JIS sequences, and (3) invalid EUC-JP sequences, which allows remote attackers to conduct cross-site scripting (XSS) attacks by placing a crafted byte sequence before a special character.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2009-12-17","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2009-12-17","kind":"exploitdb","ref":"33414","stars":null,"title":"PHP 5.2.11 - 'htmlspecialCharacters()' Malformed Multibyte Character Cross-Site Scripting (1)"},{"date":"2009-12-17","kind":"exploitdb","ref":"33415","stars":null,"title":"PHP 5.2.11 - 'htmlspecialCharacters()' Malformed Multibyte Character Cross-Site Scripting (2)"}],"tier":"weaponised"},"has_fix":true,"headline":"Cross-site scripting in n/a","id":"CVE-2009-4142","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"php:php","products":["php:php"],"type":"xss","year":"2009"},"n_packages":0,"n_references":16,"next":{"headline":"Other in n/a","id":"CVE-2009-4143"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2009-4141"},"products":["n/a"],"published":"2009-12-21","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2012-2688","kev_date_added":null,"published":"2012-07-20"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2376","kev_date_added":null,"published":"2012-05-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-3268","kev_date_added":null,"published":"2011-08-25"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-4143","kev_date_added":null,"published":"2009-12-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-5557","kev_date_added":null,"published":"2008-12-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-2050","kev_date_added":null,"published":"2008-05-05"},{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2008-2051","kev_date_added":null,"published":"2008-05-05"}],"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":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can execute cross-site scripting attacks by exploiting improper handling of invalid character sequences in the PHP htmlspecialchars function.","url":"https://insights.sbomify.com/CVE-2009-4142/"}
