CVE-2022-50795 in Impact
Summary
by MITRE • 12/31/2025
SOUND4 IMPACT/FIRST/PULSE/Eco <=2.x contains a conditional command injection vulnerability that allows local authenticated users to create malicious files in the /tmp directory. Unauthenticated attackers can execute commands by making a single HTTP POST request to the traceroute.php script, which triggers the malicious file and then deletes it after execution.

The SOUND4 IMPACT/FIRST/PULSE/Eco software suite represents a critical vulnerability landscape where a conditional command injection flaw exists within versions 2.x and earlier. This vulnerability specifically targets the traceroute.php script which serves as an entry point for exploitation. The flaw stems from insufficient input validation and sanitization mechanisms that fail to properly handle user-supplied data, creating a pathway for malicious command execution. The vulnerability affects multiple variants within the SOUND4 product line, indicating a systemic issue that requires comprehensive remediation across the entire software ecosystem.
The technical implementation of this vulnerability involves a conditional command injection that operates through a specific code path within the traceroute.php script. Local authenticated users can leverage this weakness to create malicious files in the /tmp directory, which serves as a temporary storage area for executable payloads. The exploitation process begins when an unauthenticated attacker crafts a single HTTP POST request containing malicious input parameters that are then processed by the vulnerable script. The system fails to properly sanitize these inputs, allowing arbitrary commands to be embedded within the execution flow. The malicious file creation mechanism operates through a temporary file handling routine that places the crafted payload in /tmp, where it remains accessible for execution before being automatically removed.
The operational impact of this vulnerability extends beyond simple command execution capabilities to encompass a complete compromise of system integrity and availability. The ability to execute commands through unauthenticated HTTP POST requests represents a severe privilege escalation vector that can be leveraged by attackers without requiring legitimate credentials. The temporary file creation process creates a window of opportunity for malicious execution, while the automatic deletion mechanism provides an additional layer of stealth that complicates forensic analysis. Attackers can potentially establish persistent access, escalate privileges, or conduct reconnaissance activities through the executed commands, making this vulnerability particularly dangerous in networked environments where multiple systems may be running affected software versions.
Mitigation strategies for this vulnerability must address both immediate remediation needs and long-term architectural improvements to prevent similar issues. The primary recommendation involves applying the latest security patches provided by SOUND4 to upgrade to versions that contain proper input validation and sanitization mechanisms. Organizations should implement network segmentation and access controls to limit exposure of the vulnerable traceroute.php endpoint to unauthorized users. Additionally, monitoring systems should be configured to detect unusual HTTP POST requests targeting the affected script, particularly those containing suspicious parameter patterns that may indicate exploitation attempts. The implementation of web application firewalls and input validation rules can provide additional layers of protection. This vulnerability aligns with CWE-77 and CWE-78 categories related to command injection, and maps to ATT&CK techniques involving command and script execution with privileges escalation capabilities. Regular security assessments and vulnerability scanning should be conducted to identify and remediate similar issues within the broader software ecosystem.
