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-2013-4123 exists.\n\nAffected product: Opensuse Opensuse. 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-2013-4123/ (Markdown: https://insights.sbomify.com/CVE-2013-4123/index.md)","id":"CVE-2013-4123","markdown":"https://insights.sbomify.com/CVE-2013-4123/index.md","name":"CVE-2013-4123","record":{"aliases":["GHSA-gpv8-rwm7-v9hg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Squid proxy server","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Squid proxy servers by sending a crafted port number in the HTTP Host header.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"opensuse","vendor":"opensuse"},{"product":"squid","vendor":"squid-cache"}],"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":"client_side_request.cc in Squid 3.2.x before 3.2.13 and 3.3.x before 3.3.8 allows remote attackers to cause a denial of service via a crafted port number in a HTTP Host header.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2013-07-16","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2013-07-16","kind":"exploitdb","ref":"26886","stars":null,"title":"Squid 3.3.5 - Denial of Service (PoC)"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2013-4123","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensuse:opensuse","products":["opensuse:opensuse","squid-cache:squid"],"type":"denial_of_service","year":"2013"},"n_packages":0,"n_references":6,"next":{"headline":"Integer overflow in n/a","id":"CVE-2013-4124"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2013-4122"},"products":["n/a"],"published":"2013-09-16","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2015-5957","kev_date_added":null,"published":"2015-09-28"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2015-0491","kev_date_added":null,"published":"2015-04-16"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2008-2388","kev_date_added":null,"published":"2008-06-06"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2010-1866","kev_date_added":null,"published":"2010-05-07"},{"cvss_score":9.3,"headline":"Other in n/a","id":"CVE-2015-0492","kev_date_added":null,"published":"2015-04-16"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2014-0158","kev_date_added":null,"published":"2018-04-10"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2016-4343","kev_date_added":null,"published":"2016-05-22"}],"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":"2024-09-17","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in Squid proxy servers by sending a crafted port number in the HTTP Host header.","url":"https://insights.sbomify.com/CVE-2013-4123/"}
