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-2014-4172 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jasig.cas:cas-client (Maven): affected all versions; fixed in 3.3.2\n- org.jasig.cas:cas-client (Maven): affected all versions; fixed in 3.3.2\n- DotNetCasClient (NuGet): affected all versions; fixed in 1.0.2\n- DotNetCasClient (NuGet): affected all versions; fixed in 1.0.2\n- jasig/phpcas (Packagist): affected all versions; fixed in 1.3.3\n- jasig/phpcas (Packagist): affected all versions; fixed in 1.3.3\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-2014-4172/ (Markdown: https://insights.sbomify.com/CVE-2014-4172/index.md)","id":"CVE-2014-4172","markdown":"https://insights.sbomify.com/CVE-2014-4172/index.md","name":"CVE-2014-4172","record":{"aliases":["DEBIAN-CVE-2014-4172","DSA-3017-1","GHSA-9fc5-q25c-r2wr","MGASA-2014-0387"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CAS client library","requires_auth":"none","summary":"Remote attackers can inject arbitrary web script or HTML via URL parameters in CAS client libraries, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":".net_cas_client","vendor":"apereo"},{"product":"java_cas_client","vendor":"apereo"},{"product":"phpcas","vendor":"apereo"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"A URL parameter injection vulnerability was found in the back-channel ticket validation step of the CAS protocol in Jasig Java CAS Client before 3.3.2, .NET CAS Client before 1.0.2, and phpCAS before 1.3.3 that allow remote attackers to inject arbitrary web script or HTML via the (1) service parameter to validation/AbstractUrlBasedTicketValidator.java or (2) pgtUrl parameter to validation/Cas20ServiceTicketValidator.java.","ecosystems":["Maven","NuGet","Packagist"],"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":"Jasig Java CAS Client, .NET CAS Client, and phpCAS contain URL parameter injection vulnerability","id":"CVE-2014-4172","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora"],"type":"xss","year":"2014"},"n_packages":6,"n_references":11,"next":{"headline":"Memory corruption in n/a","id":"CVE-2014-4174"},"packages":[{"ecosystem":"Maven","fixed":["3.3.2"],"introduced":["0"],"last_affected":[],"package":"org.jasig.cas:cas-client","purl":null,"source":"GHSA-9fc5-q25c-r2wr"},{"ecosystem":"Maven","fixed":["3.3.2"],"introduced":["0"],"last_affected":[],"package":"org.jasig.cas:cas-client","purl":"pkg:maven/org.jasig.cas/cas-client","source":"GHSA-9fc5-q25c-r2wr"},{"ecosystem":"NuGet","fixed":["1.0.2"],"introduced":["0"],"last_affected":[],"package":"DotNetCasClient","purl":null,"source":"GHSA-9fc5-q25c-r2wr"},{"ecosystem":"NuGet","fixed":["1.0.2"],"introduced":["0"],"last_affected":[],"package":"DotNetCasClient","purl":"pkg:nuget/DotNetCasClient","source":"GHSA-9fc5-q25c-r2wr"},{"ecosystem":"Packagist","fixed":["1.3.3"],"introduced":["0"],"last_affected":[],"package":"jasig/phpcas","purl":null,"source":"GHSA-9fc5-q25c-r2wr"},{"ecosystem":"Packagist","fixed":["1.3.3"],"introduced":["0"],"last_affected":[],"package":"jasig/phpcas","purl":"pkg:composer/jasig/phpcas","source":"GHSA-9fc5-q25c-r2wr"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2014-4171"},"products":["n/a"],"published":"2020-01-24","related":[],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can inject arbitrary web script or HTML via URL parameters in CAS client libraries, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2014-4172/"}
