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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["http://www.openwall.com/lists/oss-security/2021/04/15/1","https://lists.apache.org/thread.html/5173c4eed06e2fca6fd5576ed723ff6bb1711738ec515cb51a04ab24%40%3Cusers.tapestry.apache.org%3E","https://lists.apache.org/thread.html/6c40c1e03d2131119f9b77882431a0050f02bf9cae9ee48b84d012df%40%3Cusers.tapestry.apache.org%3E","https://lists.apache.org/thread.html/a4092cb3bacb143571024e79c0016c039b6c982423daa33a7a5c794a%40%3Cusers.tapestry.apache.org%3E","https://lists.apache.org/thread.html/r237ff7f286bda31682c254550c1ebf92b0ec61329b32fbeb2d1c8751%40%3Cusers.tapestry.apache.org%3E"],"products":["apache:tapestry"],"source":"nvd","synced_at":"2026-10-19T20:58:39.700375520+00:00"},"epss":{"cve":"CVE-2019-0195","score":0.1402,"percentile":0.96556,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6mwh-fw4p-75fj","url":"https://osv.dev/vulnerability/GHSA-6mwh-fw4p-75fj","summary":"Deserialization of Untrusted Data in Apache Tapestry","modified":"2023-11-08T04:00:30.919220Z","packages":[{"ecosystem":"Maven","name":"org.apache.tapestry:tapestry-core","purl":"pkg:maven/org.apache.tapestry/tapestry-core","ranges":[">=5.4.0 <5.4.5"],"fixed":["5.4.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
