What is CVE-2022-50795?

The SOUND4 IMPACT/FIRST/PULSE/Eco products version 2.x and below have a vulnerability that allows local authenticated users to exploit a conditional command injection. By leveraging this flaw, attackers can create malicious files in the /tmp directory. Additionally, unauthenticated users can execute commands remotely by sending a specially crafted HTTP POST request to the traceroute.php script. This request triggers the execution of the malicious file, which is then deleted post-execution, potentially allowing malicious actions without detection.

Affected Version(s)

BigVoice2 1.30

BigVoice4 1.2

Impact/Pulse Eco 1.16

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
