{"id":"CVE-2019-0195","details":"Manipulating classpath asset file URLs, an attacker could guess the path to a known file in the classpath and have it downloaded. If the attacker found the file with the value of the tapestry.hmac-passphrase configuration symbol, most probably the webapp's AppModule class, the value of this symbol could be used to craft a Java deserialization attack, thus running malicious injected Java code. The vector would be the t:formdata parameter from the Form component.","aliases":["GHSA-6mwh-fw4p-75fj"],"modified":"2026-07-08T20:05:05.312131Z","published":"2019-09-16T16:15:10.007Z","references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/5173c4eed06e2fca6fd5576ed723ff6bb1711738ec515cb51a04ab24%40%3Cusers.tapestry.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/6c40c1e03d2131119f9b77882431a0050f02bf9cae9ee48b84d012df%40%3Cusers.tapestry.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/a4092cb3bacb143571024e79c0016c039b6c982423daa33a7a5c794a%40%3Cusers.tapestry.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r237ff7f286bda31682c254550c1ebf92b0ec61329b32fbeb2d1c8751%40%3Cusers.tapestry.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r7d9c54beb1dc97dcccc58d9b5d31f0f7166f9a25ad1beba5f8091e0c%40%3Ccommits.tapestry.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r87523dd07886223aa086edc25fe9b8ddb9c1090f7db25b068dc30843%40%3Ccommits.tapestry.apache.org%3E"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2021/04/15/1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/tapestry-5","events":[{"introduced":"2672e9847ad56d2b3f83c28319b532b92d6af5c9"},{"last_affected":"85cc611fbad4a3574664b33ce9adf614b4f0fe07"}],"database_specific":{"cpe":"cpe:2.3:a:apache:tapestry:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"5.4.0"},{"last_affected":"5.4.3"}],"source":"CPE_RANGE"}}],"versions":["5.4.3","5.4.2","5.4.1","5.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-0195.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
