FILE-OTHER -- Snort detected traffic targeting vulnerabilities in a file type that does not require enough rule coverage to have its own category.
FILE-OTHER PEAR Archive Tar code deserialization attempt
This rule looks for a vulnerable file handler protocol in the PEAR software when dealing with TAR files while using the Phar protocol. A maliciously crafted file could lead to an insecure data deserialization which could take to execute code in the target computer as a privileged user.
This rule will alert when there's an attempt to execute code via a malicious deserialization using Phar file handler protocl

Insecure Deserialization
Insecure Deserialization relates to web application security. Applications turn an object into data through serialization; the reverse of that process, deserialization, can be vulnerable to attacks when the application trusts the data that is being deserialized. Serialized data is machine readable and not encrypted; serialized user-supplied data should not be trusted. Deserialization attacks can lead to remote code execution.
