Apache Tapestry - Remote Code Execution

Apache Tapestry contains a critical unauthenticated remote code execution vulnerability. Affected versions include 5.4.5, 5.5.0, 5.6.2 and 5.7.0. Note that this vulnerability is a bypass of the fix for CVE-2019-0195. Before that fix it was possible to download arbitrary class files from the...

CVE-2019-0195

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 symbo...

A critical unauthenticated remote code execution vulnerability was found all recent versions of Apache Tapestry. The affected versions include 5.4.5, 5.5.0, 5.6.2 and 5.7.0. The vulnerability I have found is a bypass of the fix for CVE-2019-0195. Recap: Before the fix of CVE-2019-0195 it was...

Remote Code Execution

tapestry-core is vulnerable to remote code execution. Access to the classpath asset files is not restricted, allowing an attacker to guess the path to a known file in the classpath and retrieve the contents. It can also potentially allow the attacker to perform a Java serialization attack if the...
