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-2011-2768 in the wild and no public exploit code.\n\nAffected product: Tor Tor. 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-2011-2768/ (Markdown: https://insights.sbomify.com/CVE-2011-2768/index.md)","id":"CVE-2011-2768","markdown":"https://insights.sbomify.com/CVE-2011-2768/index.md","name":"CVE-2011-2768","record":{"aliases":["DEBIAN-CVE-2011-2768","GHSA-h978-fv3x-h43g"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Tor anonymity network","requires_auth":"none","summary":"Remote relays can bypass Tor anonymity by reading TLS certificate chains to identify client entry guards, compromising user privacy.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tor","vendor":"tor"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"Tor before 0.2.2.34, when configured as a client or bridge, sends a TLS certificate chain as part of an outgoing OR connection, which allows remote relays to bypass intended anonymity properties by reading this chain and then determining the set of entry guards that the client or bridge had selected.","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":"Information disclosure in n/a","id":"CVE-2011-2768","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tor:tor","products":["tor:tor"],"type":"information_disclosure","year":"2011"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2011-2769"},"packages":[],"prev":{"headline":"Code injection in mod perl 2.0 through 2.0.10","id":"CVE-2011-2767"},"products":["n/a"],"published":"2011-12-23","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-1676","kev_date_added":null,"published":"2010-12-22"},{"cvss_score":10,"headline":"Tor before 0.2.0.34 treats incomplete IPv4 addresses as valid, which has unknown impact and attack vectors related to \"Spec conformance,\" as","id":"CVE-2009-0939","kev_date_added":null,"published":"2009-03-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-0414","kev_date_added":null,"published":"2009-02-03"},{"cvss_score":9.3,"headline":"Information disclosure in n/a","id":"CVE-2008-5398","kev_date_added":null,"published":"2008-12-09"},{"cvss_score":7.6,"headline":"Memory corruption in n/a","id":"CVE-2011-2778","kev_date_added":null,"published":"2011-12-23"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2006-3409","kev_date_added":null,"published":"2006-07-07"},{"cvss_score":7.2,"headline":"Privilege escalation in n/a","id":"CVE-2008-5397","kev_date_added":null,"published":"2008-12-09"}],"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 relays can bypass Tor anonymity by reading TLS certificate chains to identify client entry guards, compromising user privacy.","url":"https://insights.sbomify.com/CVE-2011-2768/"}
