CVE-2019-25584: RarmaRadio Buffer Overflow Vulnerability

CVE-2019-25584 Overview

CVE-2019-25584 is a buffer overflow vulnerability affecting RarmaRadio version 2.72.3. The vulnerability exists in the Server field of the Network settings, allowing local attackers to crash the application by supplying an excessively long string. Attackers can paste a malicious payload exceeding 4000 bytes into the Server field via the Settings menu to trigger an application crash, resulting in a denial of service condition.

Critical Impact

Local attackers can cause a denial of service by crashing the RarmaRadio application through buffer overflow exploitation in the Network settings Server field.

Technical Details for CVE-2019-25584

Vulnerability Analysis

This vulnerability is classified as CWE-787 (Out-of-bounds Write), a memory corruption issue where the application fails to properly validate the length of user-supplied input before copying it into a fixed-size buffer. The vulnerability requires local access to exploit, as an attacker must interact with the application's Settings menu to inject the malicious payload. While the attack complexity is low and requires no special privileges or user interaction beyond accessing the vulnerable input field, the impact is limited to availability—causing the application to crash without compromising data confidentiality or integrity.

Root Cause

The root cause of this vulnerability is improper bounds checking in the Server field input handler within the Network settings component. When a user inputs data into this field, the application allocates a fixed-size buffer to store the value but fails to validate that the input length does not exceed the buffer's capacity. When data exceeding approximately 4000 bytes is provided, it overwrites adjacent memory locations, corrupting the application's memory state and causing a crash.

Attack Vector

The attack vector for CVE-2019-25584 is local, requiring an attacker to have access to the system running RarmaRadio. The exploitation process involves navigating to the Settings menu within the application, locating the Network settings section, and pasting a crafted payload of more than 4000 bytes into the Server field. Upon submission or when the application attempts to process the oversized input, the buffer overflow is triggered, causing the application to crash.

This vulnerability does not require any special privileges to exploit, and no user interaction beyond the attacker's own actions is needed. The primary impact is denial of service through application crash, with no evidence of code execution capability.

Detection Methods for CVE-2019-25584

Indicators of Compromise

• Application crash logs indicating memory access violations or buffer overflows in rarmaradio.exe
• Windows Event Log entries showing application faults with exception codes related to memory corruption
• Unusually large clipboard contents being pasted into the RarmaRadio application

Detection Strategies

• Monitor for repeated crashes of the RarmaRadio application that may indicate exploitation attempts
• Implement application whitelisting and user activity monitoring to detect suspicious interactions with vulnerable software
• Deploy endpoint detection solutions capable of identifying buffer overflow exploitation patterns

Monitoring Recommendations

• Review system crash dumps and application error reports for RarmaRadio-related memory corruption events
• Monitor for unauthorized access to systems with RarmaRadio installed
• Maintain asset inventory to track systems running the vulnerable version 2.72.3

How to Mitigate CVE-2019-25584

Immediate Actions Required

• Identify all systems running RarmaRadio version 2.72.3 and prioritize remediation
• Consider removing or disabling RarmaRadio on systems where it is not essential
• Restrict local access to systems running the vulnerable application to trusted users only
• Evaluate alternative software if the vendor has not released a patched version

Patch Information

No vendor patch information is available in the current CVE data. Users should check the Raimersoft Home Page for potential updates or contact the vendor directly for remediation guidance. Additional technical details are available via the VulnCheck Advisory and Exploit-DB #46899.

Workarounds

• Restrict access to the RarmaRadio Settings menu through application configuration if possible
• Limit local user access to systems running the vulnerable software
• Consider deploying application sandboxing to contain potential crashes
• Monitor for and block clipboard operations containing excessively long strings when interacting with the application
