Summary
by MITRE • 03/22/2026
RarmaRadio 2.72.3 contains a buffer overflow vulnerability in the Server field of the Network settings that allows 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.

The vulnerability identified as CVE-2019-25584 represents a critical buffer overflow flaw within RarmaRadio version 2.72.3 that specifically targets the Network settings configuration interface. This issue resides in the Server field parameter handling mechanism where the application fails to properly validate input length before processing user-supplied data. The vulnerability manifests when a local attacker provides an excessively long string exceeding 4000 bytes through the Settings menu interface, directly compromising the application's memory management and execution flow. The buffer overflow occurs due to inadequate bounds checking in the input validation routine that processes network server configuration parameters, creating a scenario where memory corruption can occur when the application attempts to store data beyond allocated buffer boundaries.
From a technical perspective, this vulnerability operates as a classic stack-based buffer overflow that occurs within the application's network configuration handling subsystem. The flaw stems from the application's failure to implement proper input length validation before copying user-provided data into fixed-size memory buffers. When the Server field receives input exceeding 4000 bytes, the application's internal buffer management mechanism becomes compromised, leading to memory corruption that ultimately results in application termination. This type of vulnerability falls under the Common Weakness Enumeration category CWE-121, which specifically addresses stack-based buffer overflow conditions, and CWE-122, which covers heap-based buffer overflow scenarios. The vulnerability demonstrates characteristics consistent with the attack pattern described in MITRE ATT&CK framework under T1499.004 for Network Denial of Service, as it enables an attacker to cause application instability and system unavailability.
The operational impact of this vulnerability extends beyond simple application crashes to potentially enable more sophisticated attack vectors when combined with other exploitation techniques. Local attackers can leverage this vulnerability to disrupt normal application functionality and potentially gain unauthorized access to system resources through application instability. The crash condition can be reliably triggered through the Settings menu interface, making it accessible to any user with local system access, which significantly broadens the potential threat surface. The vulnerability's local nature means that no network connectivity is required for exploitation, reducing the attack complexity and increasing the likelihood of successful exploitation. Furthermore, the predictable crash behavior can be exploited in conjunction with other local privilege escalation techniques or can be used to create a denial of service condition that affects system availability. The vulnerability's impact is particularly concerning in environments where RarmaRadio is used for critical audio streaming or broadcasting operations, as the application crash could result in service interruptions and data loss.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and bounds checking mechanisms within the application's configuration handling code. The most effective immediate solution involves patching the application to enforce strict length limitations on the Server field input, ensuring that no user-provided data exceeds the allocated buffer size. Security measures should include implementing defensive programming practices such as using safe string handling functions, implementing input sanitization routines, and establishing proper memory management protocols. Organizations should also consider implementing application hardening measures including stack canaries, address space layout randomization, and data execution prevention mechanisms to reduce the exploitability of similar vulnerabilities. Additionally, regular security assessments and code reviews should be conducted to identify and remediate similar buffer overflow conditions in other application components. The vulnerability serves as a reminder of the critical importance of input validation in preventing buffer overflow exploits and underscores the necessity of following secure coding practices as outlined in industry standards such as the OWASP Secure Coding Practices and NIST guidelines for software security development.
