An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2015-8562 exists.\n\nAffected product: Joomla Joomla\\!. 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-2015-8562/ (Markdown: https://insights.sbomify.com/CVE-2015-8562/index.md)","id":"CVE-2015-8562","markdown":"https://insights.sbomify.com/CVE-2015-8562/index.md","name":"CVE-2015-8562","record":{"aliases":["GHSA-pccq-v233-rx3q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla CMS","requires_auth":"none","summary":"Remote attackers can execute arbitrary PHP code via unsafe deserialization in the User-Agent header, requiring immediate upgrades.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"joomla\\!","vendor":"joomla"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Joomla! 1.5.x, 2.x, and 3.x before 3.4.6 allow remote attackers to conduct PHP object injection attacks and execute arbitrary PHP code via the HTTP User-Agent header, as exploited in the wild in December 2015.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2015-12-14","github_poc":11,"max_poc_stars":12,"metasploit":1,"nuclei":1,"refs":[{"date":"2017-09-17T15:03:53Z","kind":"github_poc","ref":"https://github.com/VoidSec/Joomla_CVE-2015-8562","stars":12,"title":"A proof of concept for Joomla's CVE-2015-8562 vulnerability (Object Injection RCE)"},{"date":"2016-01-04T13:37:25Z","kind":"github_poc","ref":"https://github.com/ZaleHack/joomla_rce_CVE-2015-8562","stars":8,"title":"All versions of the Joomla! below 3.4.6 are known to be vulnerable.
