CVE-2019-25583 Overview
CVE-2019-25583 is a denial of service vulnerability affecting RarmaRadio version 2.72.3. The vulnerability exists in the Username field within the application's Network settings, where improper input validation allows local attackers to crash the application by submitting excessively long input. An attacker can navigate to Settings > Network and paste a buffer of approximately 5000 bytes into the Username field to trigger an application crash.
Critical Impact
Local attackers can cause complete application denial of service by exploiting improper input validation in the Username field, leading to application crashes and potential loss of user data.

Technical Details for CVE-2019-25583
Vulnerability Analysis
This vulnerability is classified as CWE-1282, which relates to assumed-immutable data being stored in writable memory. The application fails to properly validate the length of user-supplied input in the Username field within the Network settings dialog. When a user or local attacker pastes an excessively long string (approximately 5000 bytes) into this field, the application is unable to handle the oversized input, resulting in memory corruption and subsequent application crash.
The attack requires local access to the system where RarmaRadio is installed. No special privileges are required to exploit this vulnerability, and no user interaction beyond the attacker's own actions is necessary. While the vulnerability does not compromise confidentiality or integrity, it causes complete loss of availability for the affected application.
Root Cause
The root cause of this vulnerability is improper input validation in the Username field handler. The application does not enforce appropriate length restrictions on user input before processing it, allowing arbitrarily long strings to be accepted. This lack of boundary checking leads to memory handling issues when the application attempts to process or store the oversized input, ultimately causing the application to crash.
Attack Vector
The attack vector is local, requiring the attacker to have access to a system running the vulnerable version of RarmaRadio. The exploitation process is straightforward:
- Open RarmaRadio 2.72.3 on the target system
- Navigate to Settings > Network
- Locate the Username field
- Paste approximately 5000 bytes of data into the field
- The application crashes, resulting in denial of service
The vulnerability has been documented in Exploit-DB #46900, which provides additional technical details about the exploitation method. The attack is trivial to execute and requires no sophisticated techniques, making it accessible to attackers with minimal technical skills who have local system access.
Detection Methods for CVE-2019-25583
Indicators of Compromise
- Unexpected RarmaRadio application crashes or terminations
- Windows application error logs showing rarmaradio.exe crash events
- Repeated application restarts in a short time period
Detection Strategies
- Monitor Windows Event Logs for application crash events related to rarmaradio.exe
- Implement endpoint monitoring to detect unusual application behavior patterns
- Use application whitelisting to track and log access to RarmaRadio settings
Monitoring Recommendations
- Configure crash dump collection for RarmaRadio to aid in forensic analysis
- Set up alerts for repeated application crashes that may indicate exploitation attempts
- Review system access logs to identify unauthorized local access
How to Mitigate CVE-2019-25583
Immediate Actions Required
- Restrict local access to systems running vulnerable versions of RarmaRadio
- Consider temporarily disabling network proxy settings if not required
- Monitor the Raimersoft Official Website for security updates
- Evaluate alternative internet radio applications if the software is business-critical
