CVE-2019-25596 in SpotAuditor
Summary
by MITRE • 03/22/2026
SpotAuditor 5.2.6 contains a denial of service vulnerability in the registration dialog that allows local attackers to crash the application by supplying an excessively long string in the Name field. Attackers can paste a buffer of 300 repeated characters into the Name input during registration to trigger an application crash.

The vulnerability identified as CVE-2019-25596 represents a classic buffer overflow condition within the SpotAuditor 5.2.6 software application. This issue manifests specifically within the registration dialog component where the application fails to properly validate input length for the Name field. The flaw stems from inadequate bounds checking mechanisms that do not restrict the maximum allowable length of user-supplied data, creating a scenario where malicious input can overwhelm the allocated memory space. The vulnerability is classified under CWE-121 as a stack-based buffer overflow, which occurs when a program writes data beyond the boundaries of a fixed-length buffer allocated on the stack. This type of vulnerability is particularly dangerous because it can lead to unpredictable application behavior and potential system compromise.
The technical exploitation of this vulnerability requires minimal effort from an attacker as it involves simply pasting a 300-character repeated string into the Name input field during the registration process. The application's failure to implement proper input sanitization allows this excessive data to overwrite adjacent memory locations, ultimately causing the application to terminate abruptly. This denial of service condition affects the availability of the SpotAuditor application, preventing legitimate users from completing the registration process and potentially disrupting normal system operations. The vulnerability is categorized as a local attack vector since it requires physical access or user interaction within the system where the application is installed, making it accessible to anyone with local privileges or the ability to interact with the application interface.
The operational impact of CVE-2019-25596 extends beyond simple application instability, as it represents a broader class of vulnerabilities that can be exploited to disrupt service availability. From an attacker's perspective, this vulnerability aligns with techniques described in the MITRE ATT&CK framework under the T1499 category for network denial of service, though specifically manifesting as a local service disruption. The vulnerability demonstrates poor software engineering practices in input validation and memory management, which can serve as a gateway for more sophisticated attacks if the application is part of a larger attack surface. Organizations using SpotAuditor 5.2.6 face potential operational disruption during registration attempts, which could be exploited by malicious actors to deny service to legitimate users or as part of a broader attack strategy targeting system availability.
The recommended mitigation strategies for this vulnerability include immediate patching of the SpotAuditor application to version 5.2.7 or later, which contains the necessary input validation fixes. System administrators should also implement additional protective measures such as input length restrictions at the application level, regular security assessments, and monitoring for unusual registration patterns. The vulnerability highlights the importance of following secure coding practices and implementing proper bounds checking as outlined in the OWASP Secure Coding Practices. Organizations should also consider deploying application whitelisting solutions and maintaining up-to-date vulnerability management processes to prevent similar issues from affecting other software components within their infrastructure. Regular security training for development teams on buffer overflow prevention and input validation techniques remains crucial for preventing such vulnerabilities from being introduced into software products.
