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-2011-4885 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-2011-4885/ (Markdown: https://insights.sbomify.com/CVE-2011-4885/index.md)","id":"CVE-2011-4885","markdown":"https://insights.sbomify.com/CVE-2011-4885/index.md","name":"CVE-2011-4885","record":{"aliases":["GHSA-q9pr-6h9m-h8vf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP interpreter","requires_auth":"none","summary":"Remote attackers can cause CPU exhaustion and denial of service by sending crafted form parameters that trigger predictable hash collisions in PHP.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"PHP before 5.3.9 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.","ecosystems":[],"exploits":{"exploitdb":3,"first_seen":"2006-07-15","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2006-07-15","kind":"exploitdb","ref":"2012","stars":null,"title":"MyBulletinBoard (MyBB) 1.1.5 - 'CLIENT-IP' SQL Injection"},{"date":"2011-12-28","kind":"metasploit","ref":"auxiliary/dos/http/hashcollision_dos","stars":null,"title":"Hashtable Collisions"},{"date":"2012-01-01","kind":"exploitdb","ref":"18296","stars":null,"title":"PHP 5.3.8 - Hashtables Denial of Service"},{"date":"2012-01-03","kind":"exploitdb","ref":"18305","stars":null,"title":"PHP Hash Table Collision - Denial of Service (PoC)"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2011-4885","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"php:php","products":["php:php"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":30,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2011-4887"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-4883"},"products":["n/a"],"published":"2011-12-30","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":"BSD-3-Clause","name":"Metasploit"},{"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 cause CPU exhaustion and denial of service by sending crafted form parameters that trigger predictable hash collisions in PHP.","url":"https://insights.sbomify.com/CVE-2011-4885/"}
