CVE-2024-3798: high-severity vulnerability in Phoniebox

Insecure handling of GET header parameter file included in requests being sent to an instance of the open-source project Phoniebox allows an attacker to create a website, which – when visited by a user – will send malicious requests to multiple hosts on the local network. If such a request reaches the server, it will cause one of the following (depending on the chosen payload): shell command execution, reflected XSS or cross-site request forgery. This issue affects Phoniebox in all releases through 2.7. Newer 2.x releases were not tested, but they might also be vulnerable.  Phoniebox in version 3.0 and higher are not affected.
