A vulnerability classified as problematic was found in Apache Tapestry 5.4.0/5.4.1/5.4.2/5.4.3. This vulnerability affects the function AppModule. The manipulation of the argument t:formdata as part of a Parameter leads to a deserialization vulnerability. The CWE definition for the vulnerability is CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. As an impact it is known to affect confidentiality. CVE summarizes:

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.
