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-2013-2566 exists.\n\nAffected product: Canonical Ubuntu Linux. 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-2013-2566/ (Markdown: https://insights.sbomify.com/CVE-2013-2566/index.md)","id":"CVE-2013-2566","markdown":"https://insights.sbomify.com/CVE-2013-2566/index.md","name":"CVE-2013-2566","record":{"aliases":["GHSA-f67x-vqh9-8p43"],"analysis":{"component_type":"other","fix_type":"configuration_change","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"TLS/SSL protocol","requires_auth":"none","summary":"Remote attackers can recover plaintext from TLS/SSL sessions using RC4 due to statistical biases, requiring disabling RC4 ciphers.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"m10-1_firmware","vendor":"fujitsu"},{"product":"m10-4_firmware","vendor":"fujitsu"},{"product":"m10-4s_firmware","vendor":"fujitsu"},{"product":"sparc_enterprise_m3000_firmware","vendor":"fujitsu"},{"product":"sparc_enterprise_m4000_firmware","vendor":"fujitsu"},{"product":"sparc_enterprise_m5000_firmware","vendor":"fujitsu"},{"product":"sparc_enterprise_m8000_firmware","vendor":"fujitsu"},{"product":"sparc_enterprise_m9000_firmware","vendor":"fujitsu"},{"product":"firefox","vendor":"mozilla"},{"product":"seamonkey","vendor":"mozilla"},{"product":"thunderbird","vendor":"mozilla"},{"product":"thunderbird_esr","vendor":"mozilla"},{"product":"communications_application_session_controller","vendor":"oracle"},{"product":"http_server","vendor":"oracle"},{"product":"integrated_lights_out_manager_firmware","vendor":"oracle"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-326","name":"Inadequate Encryption Strength"},{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2014-10-14","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2014-10-14","kind":"metasploit","ref":"auxiliary/scanner/ssl/ssl_version","stars":null,"title":"SSL/TLS Version Detection"}],"tier":"weaponised"},"has_fix":true,"headline":"Weak cryptography in n/a","id":"CVE-2013-2566","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","mozilla:firefox","mozilla:seamonkey","mozilla:thunderbird","mozilla:thunderbird_esr","oracle:http_server"],"type":"weak_cryptography","year":"2013"},"n_packages":0,"n_references":22,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2013-2567"},"packages":[],"prev":{"headline":"Information disclosure in Mambo CMS","id":"CVE-2013-2565"},"products":["n/a"],"published":"2013-03-14","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-22","vendors":["n/a"]},"summary":"Remote attackers can recover plaintext from TLS/SSL sessions using RC4 due to statistical biases, requiring disabling RC4 ciphers.","url":"https://insights.sbomify.com/CVE-2013-2566/"}
