Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-4320 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ejabberd (Hex): affected all versions; fixed in 2.1.9\n- ejabberd (Hex): affected all versions; fixed in 2.1.9\n- ejabberd (Hex): affected from 3.0.0-alpha-1; fixed in 3.0.0-alpha-4\n- ejabberd (Hex): affected from 3.0.0-alpha-1; fixed in 3.0.0-alpha-4\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-2011-4320/ (Markdown: https://insights.sbomify.com/CVE-2011-4320/index.md)","id":"CVE-2011-4320","markdown":"https://insights.sbomify.com/CVE-2011-4320/index.md","name":"CVE-2011-4320","record":{"aliases":["DEBIAN-CVE-2011-4320","GHSA-2h3q-v47h-f4rc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XMPP server","requires_auth":"low_privilege","summary":"Remote authenticated users can cause a denial of service in ejabberd via a malformed publish stanza, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ejabberd","vendor":"process-one"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"The mod_pubsub module (mod_pubsub.erl) in ejabberd 2.1.8 and 3.0.0-alpha-3 allows remote authenticated users to cause a denial of service (infinite loop) via a stanza with a publish tag that lacks a node attribute.","ecosystems":["Hex"],"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":"Ejabberd DoS via malformed stanza","id":"CVE-2011-4320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"denial_of_service","year":"2011"},"n_packages":4,"n_references":6,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2011-4321"},"packages":[{"ecosystem":"Hex","fixed":["2.1.9"],"introduced":["0"],"last_affected":[],"package":"ejabberd","purl":null,"source":"GHSA-2h3q-v47h-f4rc"},{"ecosystem":"Hex","fixed":["2.1.9"],"introduced":["0"],"last_affected":[],"package":"ejabberd","purl":"pkg:hex/ejabberd","source":"GHSA-2h3q-v47h-f4rc"},{"ecosystem":"Hex","fixed":["3.0.0-alpha-4"],"introduced":["3.0.0-alpha-1"],"last_affected":[],"package":"ejabberd","purl":null,"source":"GHSA-2h3q-v47h-f4rc"},{"ecosystem":"Hex","fixed":["3.0.0-alpha-4"],"introduced":["3.0.0-alpha-1"],"last_affected":[],"package":"ejabberd","purl":"pkg:hex/ejabberd","source":"GHSA-2h3q-v47h-f4rc"}],"prev":{"headline":"Cross-site Scripting vulnerability in i18n translations helper method","id":"CVE-2011-4319"},"products":["n/a"],"published":"2012-02-18","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2007-0903","kev_date_added":null,"published":"2007-02-13"},{"cvss_score":5,"headline":"Security feature bypass in n/a","id":"CVE-2014-8760","kev_date_added":null,"published":"2014-10-25"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2011-1753","kev_date_added":null,"published":"2011-06-21"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2010-0305","kev_date_added":null,"published":"2010-02-03"},{"cvss_score":4.3,"headline":"Weak cryptography in n/a","id":"CVE-2013-6169","kev_date_added":null,"published":"2013-10-17"},{"cvss_score":4.3,"headline":"Cross-site scripting in n/a","id":"CVE-2009-0934","kev_date_added":null,"published":"2009-03-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote authenticated users can cause a denial of service in ejabberd via a malformed publish stanza, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2011-4320/"}
