CVE-2018-25280 is a buffer overflow vulnerability affecting Infiltrator Network Security Scanner 4.6. This vulnerability allows local attackers to crash the application by supplying an oversized input string. Specifically, attackers can paste a 6000-byte payload into the Scan Target field and trigger a denial of service condition when the Scan button is clicked. The severity of this vulnerability is classified as medium, with a CVSS score of 6.8.
The implications of this vulnerability pose significant risks to organizations relying on this software for network security. Attackers may leverage this vulnerability to disrupt operations, leading to potential downtime and loss of productivity. Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
As of now, there is no confirmed public exploit available for CVE-2018-25280, and it is not actively being exploited in the wild. However, the local nature of the attack vector combined with the low complexity of the exploit means that it could be executed by an attacker with minimal effort. Therefore, it is essential for organizations to remain vigilant.
Organizations using Infiltrator Network Security Scanner 4.6 are advised to assess their exposure to this vulnerability and take appropriate steps to remediate it. This includes applying any available patches or updates as soon as they are released.
Vulnerability Details
The official description of CVE-2018-25280 states that it is a buffer overflow vulnerability in Infiltrator Network Security Scanner 4.6, allowing local attackers to crash the application through an oversized input string. The CVSS score associated with this vulnerability is 6.8, indicating a medium severity level, as it impacts the application's availability significantly while posing no confidentiality or integrity risks.
The vulnerability is classified under CWE-120, which refers to buffer copy without checking size of input. The vulnerability was published on April 26, 2026, and organizations should be aware that it affects Infiltrator Network Security Scanner 4.6.
Technical Analysis
The root cause of CVE-2018-25280 is a buffer overflow in the application, which occurs when the application fails to validate the size of the input string. The attack vector is local, meaning the attacker must have access to the system running the scanner. The attack complexity is considered low, as no special conditions are required for exploitation.
The privileges required to exploit this vulnerability are none, but user interaction is required to trigger the denial of service condition. When the oversized payload is submitted, the application crashes, leading to high availability impact. There are no confidentiality or integrity impacts associated with this vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential downtime due to application crashes, which can disrupt services and lead to a loss of productivity. The blast radius is limited to systems running Infiltrator Network Security Scanner 4.6, but unmitigated exploitation could allow an attacker to control the application and affect its functionalities.
Given the CVSS score of 6.8, organizations should assess the urgency of addressing this vulnerability. It is crucial to understand that while there is currently no active exploitation, the nature of the vulnerability allows for easy attack execution, which may change over time.
