CVE-2019-0195 is a critical deserialization vulnerability affecting Apache Tapestry. An attacker can manipulate classpath asset file URLs to download sensitive files, specifically the tapestry.hmac-passphrase from the webapp's AppModule class. This passphrase can then be used to craft a Java deserialization attack via the t:formdata parameter of the Form component, leading to arbitrary code execution. With a CVSS score of 9.8 (CRITICAL), this vulnerability has a high impact on confidentiality, integrity, and availability, and requires no user interaction or complex attack steps. While there is no evidence of active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion, indicating awareness and potential for future exploitation.
