CVE-2025-25528 outlines multiple buffer overflow vulnerabilities present in Wavlink WL-WN575A3 RPT75A3.V4300. These vulnerabilities arise due to the failure to perform strict length checks on user-controlled data. Attackers may exploit these vulnerabilities to crash remote devices or execute arbitrary commands without any form of authorization verification. The CVSS score for this vulnerability is 5.1, indicating a medium severity level that necessitates prompt attention from security teams.
The potential for exploitation of these vulnerabilities poses significant risks. Organizations utilizing the affected devices should be aware of the implications, as unauthorized access can lead to severe operational disruptions. Given the medium severity rating, organizations are advised to address this vulnerability within their priority patch cycle.
As of now, there are no known public exploits for this vulnerability, thus organizations can focus on remediation strategies without the immediate threat of active exploitation. However, it remains crucial to monitor developments closely.
Organizations should prioritize patching immediately to safeguard their systems and maintain operational integrity.
Vulnerability Details
The vulnerabilities in question are classified as buffer overflow vulnerabilities, specifically identified under CWE-120. The CVSS score of 5.1 signifies a medium severity, with the attack vector classified as local, which implies that an attacker requires physical or local network access to exploit the vulnerabilities. The attack complexity is low, meaning successful exploitation is relatively straightforward. Importantly, no privileges are required to exploit the vulnerabilities, and user interaction is not necessary.
The affected product is the Wavlink WL-WN575A3 firmware with the specific version RPT75A3.V4300. The vulnerabilities were published on February 11, 2025, and are still under analysis, indicating the ongoing evaluation of their impact and potential fixes.
Technical Analysis
The root cause of the buffer overflow vulnerabilities stems from inadequate length checks on user-controlled data. When these checks are not enforced, attackers can provide input that exceeds the allocated buffer size, leading to unexpected behavior such as crashing devices or executing arbitrary commands.
The attack vector is local, meaning that a successful exploitation requires access to the device or the local network. The complexity of the attack is low, making it easier for an attacker to carry out the exploitation without sophisticated techniques. The vulnerabilities do not require any privileges, which further increases the risk, as unauthorized users can potentially exploit them.
Regarding the impacts, the confidentiality and integrity impacts are classified as low, indicating that sensitive data may not be exposed or modified. However, the availability impact is marked as none, suggesting that the vulnerabilities do not disrupt the service's availability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-25528 is significant. Organizations utilizing Wavlink WL-WN575A3 devices may face operational disruptions if attackers successfully exploit these vulnerabilities. The potential for unauthorized command execution raises concerns about the management and control of network devices.
The urgency assessment based on the CVSS score indicates that organizations should address this vulnerability within their priority patch cycle. Given that the vulnerability has been assessed with a medium severity score, it is paramount to evaluate the potential blast radius and implement mitigating strategies promptly.
