An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-1755 in the wild and no public exploit code.\n\nAffected product: Apple Mac Os X. 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-2011-1755/ (Markdown: https://insights.sbomify.com/CVE-2011-1755/index.md)","id":"CVE-2011-1755","markdown":"https://insights.sbomify.com/CVE-2011-1755/index.md","name":"CVE-2011-1755","record":{"aliases":["DEBIAN-CVE-2011-1755","GHSA-rpcf-xw9j-7c7j","RHSA-2011:0881","RHSA-2011:0882"],"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":"none","summary":"Remote attackers can cause denial of service via crafted XML with nested entities, affecting jabberd2 XMPP server deployments.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"mac_os_x","vendor":"apple"},{"product":"mac_os_x_server","vendor":"apple"},{"product":"fedora","vendor":"fedoraproject"},{"product":"jabberd2","vendor":"jabberd2"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-776","name":"Improper Restriction of Recursive Entity References in DTDs"}],"description":"jabberd2 before 2.2.14 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.","ecosystems":["Red Hat:network_proxy:5.4::el5","Red Hat:network_satellite:5.4::el5"],"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":"Denial of service in n/a","id":"CVE-2011-1755","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:mac_os_x","products":["apple:mac_os_x","apple:mac_os_x_server","fedoraproject:fedora"],"type":"denial_of_service","year":"2011"},"n_packages":4,"n_references":16,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-1756"},"packages":[{"ecosystem":"Red Hat:network_proxy:5.4::el5","fixed":["0:2.2.8-12.el5sat"],"introduced":["0"],"last_affected":[],"package":"jabberd","purl":"pkg:rpm/redhat/jabberd","source":"RHSA-2011:0881"},{"ecosystem":"Red Hat:network_proxy:5.4::el5","fixed":["0:2.2.8-12.el5sat"],"introduced":["0"],"last_affected":[],"package":"jabberd-debuginfo","purl":"pkg:rpm/redhat/jabberd-debuginfo","source":"RHSA-2011:0881"},{"ecosystem":"Red Hat:network_satellite:5.4::el5","fixed":["0:2.2.8-12.el5sat"],"introduced":["0"],"last_affected":[],"package":"jabberd","purl":"pkg:rpm/redhat/jabberd","source":"RHSA-2011:0882"},{"ecosystem":"Red Hat:network_satellite:5.4::el5","fixed":["0:2.2.8-12.el5sat"],"introduced":["0"],"last_affected":[],"package":"jabberd-debuginfo","purl":"pkg:rpm/redhat/jabberd-debuginfo","source":"RHSA-2011:0882"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-1754"},"products":["n/a"],"published":"2011-06-21","related":[{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-7169","kev_date_added":"2022-01-28","published":"2014-09-25"},{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-6271","kev_date_added":"2022-01-28","published":"2014-09-24"},{"cvss_score":9.8,"headline":"PHP-CGI Query String Parameter","id":"CVE-2012-1823","kev_date_added":"2022-03-25","published":"2012-05-11"},{"cvss_score":7.8,"headline":"Apple macOS Unspecified","id":"CVE-2021-30713","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":7.8,"headline":"Apple macOS Use-After-Free","id":"CVE-2019-8526","kev_date_added":"2023-04-17","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple OS X Authentication Bypass","id":"CVE-2015-1130","kev_date_added":"2022-02-10","published":"2015-04-10"},{"cvss_score":5.5,"headline":"Apple macOS Out-of-Bounds Read","id":"CVE-2022-22674","kev_date_added":"2022-04-04","published":"2022-05-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service via crafted XML with nested entities, affecting jabberd2 XMPP server deployments.","url":"https://insights.sbomify.com/CVE-2011-1755/"}
