CVE-2019-25615 in CD Ripper
Summary
by MITRE • 03/22/2026
Lavavo CD Ripper 4.20 contains a structured exception handling (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious string in the License Activation Name field. Attackers can craft a payload with controlled buffer data, NSEH jump instructions, and SEH handler addresses to trigger code execution and establish a bind shell on port 3110.

The vulnerability identified as CVE-2019-25615 resides within Lavavo CD Ripper version 4.20, representing a critical structured exception handling buffer overflow flaw that fundamentally compromises the application's memory integrity. This vulnerability specifically manifests when the software processes input data within the License Activation Name field, creating an exploitable condition that enables local attackers to gain unauthorized code execution privileges. The flaw stems from inadequate input validation and memory management practices that fail to properly bounds-check user-supplied data before processing it within the application's exception handling mechanisms.
The technical exploitation of this vulnerability leverages the classic SEH overwrite technique, where attackers craft malicious input strings containing specifically formatted buffer data that overflows the structured exception handler stack. The payload construction involves precise manipulation of the Non-Structured Exception handler (NSEH) jump instructions combined with carefully calculated SEH handler addresses to redirect execution flow. This methodology aligns with established exploit development patterns documented in cybersecurity literature and represents a well-understood approach to achieving arbitrary code execution through SEH-based buffer overflows. The vulnerability operates at the application level rather than at the system level, making it particularly dangerous as it requires no elevated privileges beyond local user access to exploit.
From an operational impact perspective, successful exploitation of this vulnerability allows attackers to execute arbitrary code with the privileges of the currently logged-in user, potentially enabling full system compromise through subsequent attack vectors. The vulnerability's design includes a specific bind shell mechanism that listens on port 3110, providing attackers with persistent remote access capabilities. This creates a significant risk for environments where the vulnerable application runs with elevated privileges or where users have administrative access. The local execution requirement means that the attack vector is limited to users who can interact with the system locally, but this still represents a substantial risk in multi-user environments where privilege escalation attacks could be chained with other vulnerabilities.
The vulnerability maps directly to CWE-121, which describes stack-based buffer overflow conditions, and more specifically to CWE-125, which addresses out-of-bounds read conditions that can lead to buffer overflows. From an ATT&CK framework perspective, this vulnerability aligns with T1059.001 for command and script interpreter execution and T1068 for exploit for privilege escalation. The attack surface is particularly concerning as it represents a local privilege escalation vector that can be leveraged to establish persistent access and potentially move laterally within a network environment. Organizations should consider this vulnerability as part of a broader attack chain where initial access might be gained through other means, but the presence of such an exploitable application significantly weakens overall security posture.
Mitigation strategies for this vulnerability should include immediate patching of the vulnerable application to version 4.21 or later, which contains the necessary memory bounds checking and input validation improvements. System administrators should also implement application whitelisting policies to restrict execution of vulnerable applications in enterprise environments, particularly where users have local access to systems. Network segmentation and monitoring of port 3110 traffic can help detect potential exploitation attempts, while regular security assessments should include inventory checks for vulnerable applications. Additionally, user education regarding the risks of executing untrusted software and the importance of keeping applications updated remains crucial in preventing exploitation of such vulnerabilities. The vulnerability demonstrates the importance of proper secure coding practices including input validation, bounds checking, and proper exception handling mechanisms to prevent buffer overflow conditions that can be exploited for code execution.
