It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2013-4136 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- passenger (RubyGems): affected all versions; fixed in 4.0.6\n- passenger (RubyGems): affected all versions; fixed in 4.0.6\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-2013-4136/ (Markdown: https://insights.sbomify.com/CVE-2013-4136/index.md)","id":"CVE-2013-4136","markdown":"https://insights.sbomify.com/CVE-2013-4136/index.md","name":"CVE-2013-4136","record":{"aliases":["DEBIAN-CVE-2013-4136","GHSA-w6rc-q387-vpgq","MGASA-2013-0253"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ruby web server library","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges or modify directory ownership via symlink attacks in Phusion Passenger.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"passenger","vendor":"phusion"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"ext/common/ServerInstanceDir.h in Phusion Passenger gem before 4.0.6 for Ruby allows local users to gain privileges or possibly change the ownership of arbitrary directories via a symlink attack on a directory with a predictable name in /tmp/.","ecosystems":["RubyGems"],"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":"insecure temporary directory usage in passenger","id":"CVE-2013-4136","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"path_traversal","year":"2013"},"n_packages":2,"n_references":5,"next":{"headline":"SQL injection in n/a","id":"CVE-2013-4137"},"packages":[{"ecosystem":"RubyGems","fixed":["4.0.6"],"introduced":["0"],"last_affected":[],"package":"passenger","purl":null,"source":"GHSA-w6rc-q387-vpgq"},{"ecosystem":"RubyGems","fixed":["4.0.6"],"introduced":["0"],"last_affected":[],"package":"passenger","purl":"pkg:gem/passenger","source":"GHSA-w6rc-q387-vpgq"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2013-4135"},"products":["n/a"],"published":"2013-09-30","related":[{"cvss_score":9.8,"headline":"Phusion Passenger SpawningKit Contains Arbitrary Read/Write Vulnerability","id":"CVE-2018-12026","kev_date_added":null,"published":"2018-06-17"},{"cvss_score":8.8,"headline":"Insecure Permissions in Phusion Passenger","id":"CVE-2018-12027","kev_date_added":null,"published":"2018-06-17"},{"cvss_score":7.8,"headline":"Incorrect Access Control in Phusion Passenger","id":"CVE-2018-12028","kev_date_added":null,"published":"2018-06-17"},{"cvss_score":7.8,"headline":"Phusion Passenger uses a known /tmp filename","id":"CVE-2016-10345","kev_date_added":null,"published":"2017-04-18"},{"cvss_score":7.5,"headline":"RubyGems passenger gem allows remote attackers to delete files","id":"CVE-2012-6135","kev_date_added":null,"published":"2019-11-19"},{"cvss_score":5.3,"headline":"Phusion Passenger denial of service","id":"CVE-2025-26803","kev_date_added":null,"published":"2025-02-24"},{"cvss_score":5.3,"headline":"Phusion Passenger incorrect permission assignment","id":"CVE-2018-12615","kev_date_added":null,"published":"2018-06-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-09-17","vendors":["n/a"]},"summary":"Local attackers can escalate privileges or modify directory ownership via symlink attacks in Phusion Passenger.","url":"https://insights.sbomify.com/CVE-2013-4136/"}
