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-2013-7176 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2013-7176/ (Markdown: https://insights.sbomify.com/CVE-2013-7176/index.md)","id":"CVE-2013-7176","markdown":"https://insights.sbomify.com/CVE-2013-7176/index.md","name":"CVE-2013-7176","record":{"aliases":["DEBIAN-CVE-2013-7176","GHSA-c3p6-cwjh-4h46"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Fail2ban postfix filter","requires_auth":"none","summary":"Remote attackers can block arbitrary IP addresses by sending crafted emails, causing denial of service for legitimate users.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"fail2ban","vendor":"fail2ban"}],"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":"config/filter.d/postfix.conf in the postfix filter in Fail2ban before 0.8.11 allows remote attackers to trigger the blocking of an arbitrary IP address via a crafted e-mail address that matches an improperly designed regular expression.","ecosystems":[],"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-2013-7176","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2013"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2013-7177"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2013-7175"},"products":["n/a"],"published":"2014-02-01","related":[{"cvss_score":7.5,"headline":"Command injection in n/a","id":"CVE-2012-5642","kev_date_added":null,"published":"2012-12-31"},{"cvss_score":6.8,"headline":"Denial of service in n/a","id":"CVE-2007-4321","kev_date_added":null,"published":"2007-08-14"},{"cvss_score":6.1,"headline":"Possible RCE vulnerability in mailing action using mailutils (mail-whois)","id":"CVE-2021-32749","kev_date_added":null,"published":"2021-07-16"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2013-7177","kev_date_added":null,"published":"2014-02-01"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2013-2178","kev_date_added":null,"published":"2013-08-28"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2006-6302","kev_date_added":null,"published":"2006-12-06"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can block arbitrary IP addresses by sending crafted emails, causing denial of service for legitimate users.","url":"https://insights.sbomify.com/CVE-2013-7176/"}
