CVE-2018-25290 is a medium-severity buffer overflow vulnerability identified in Easyboot 6.6.0. This vulnerability allows local attackers to exploit the Replace Text function by inputting an oversized string, leading to a denial of service. The vulnerability can be triggered by navigating to File > Tools > Replace Text and pasting a payload of 7000 bytes into the text fields. The impact is significant, as it results in application crashes, hindering user productivity and potentially causing data loss.
The vulnerability has a CVSS score of 6.9, indicating a medium severity level. It is characterized by a local attack vector with low complexity and no required privileges or user interaction. The high availability impact signifies that organizations using this version of Easyboot need to address this vulnerability promptly to avoid disruptions.
Currently, there is no known public exploit for this vulnerability. However, the potential for local exploitation should not be underestimated, and organizations must take proactive measures to mitigate the risks associated with it.
Organizations should prioritize patching immediately, as denial of service vulnerabilities can severely impact operational capabilities.
Vulnerability Details
Easyboot 6.6.0 contains a buffer overflow vulnerability in the Replace Text function that allows local attackers to crash the application by supplying an oversized string. Attackers can trigger the vulnerability by accessing File > Tools > Replace Text and pasting a 7000-byte payload into the text fields to cause a denial of service.
The CVSS score for this vulnerability is 6.9, classified as medium severity. The attack vector is local, and the complexity is low, requiring no privileges or user interaction. The availability impact is high, indicating that successful exploitation can lead to significant disruption.
Technical Analysis
The root cause of CVE-2018-25290 lies in the improper handling of input sizes within the Replace Text function of Easyboot 6.6.0. The buffer overflow occurs when an oversized string is supplied, exceeding the allocated memory space. This vulnerability can be exploited through local access, meaning an attacker must have physical or local access to the system running Easyboot.
The attack complexity is low, and no privileges are required, making it easier for potential attackers to exploit this vulnerability. User interaction is also not necessary, which increases the risk of unintentional triggering by users who may not be aware of the underlying issue.
In terms of impact, the vulnerability affects the application's availability, resulting in crashes and potential data loss. Confidentiality and integrity impacts are classified as none, which means sensitive data is not directly at risk from this vulnerability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2018-25290 is moderate, particularly for organizations that rely on Easyboot for critical operations. The ability of local attackers to cause a denial of service presents a tangible threat to productivity and operational continuity. The blast radius potential is limited to systems where Easyboot is installed, but the urgency to address this issue is underscored by its high availability impact.
Organizations should schedule remediation for this vulnerability as part of their regular patch management processes. Given the medium CVSS score, it is advisable to prioritize this vulnerability within the broader context of overall organizational risk.
