Summary
The SOUND4 IMPACT introduces an innovative process - mono and stereo parts of the signal are processed separately to obtain perfect consistency in terms of both sound and level. Therefore, in moving reception, when the FM receiver switches from stereo to mono and back to stereo, the sound variations and changes in level are reduced by over 90%. In the SOUND4 IMPACT processing chain, the stereo expander can be used substantially without any limitations.With its advanced functionalities and impressive versatility, SOUND4 PULSE gives clients the ultimate price - performance ratio, providing much more than just a processor. Flexible and powerful, it ensures perfect sound quality and full compatibility with radio broadcasting standards and can be used simultaneously for FM and HD, DAB, DRM or streaming.

Description
This vulnerability allows a local authenticated user to create a file in the /tmp directory that contains malicious commands. The file must have the filename ending with .dns.pid, and the commands in the file can only be executed once by an external unauthenticated attacker. By calling the vulnerable script and making a single HTTP POST request, the attacker can gain command execution on the system. After the request is made, the file containing the malicious commands will be deleted.Vendor
