A vulnerability has been found in MicroWord eScan Antivirus 7.0.32 on Linux and classified as critical. Affected by this vulnerability is the function passPrompt of the component USB Protection Service. The manipulation leads to stack-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
This vulnerability allows attackers to potentially execute arbitrary code on the affected system, posing a significant risk to organizations. Given its critical nature and the availability of public exploit information, the urgency for remediation is high.
Risk to organizations includes unauthorized access and potential data breaches. Organizations should prioritize patching immediately.
The vulnerability has a CVSS score of 4.8, categorized as medium severity, highlighting the need for organizations to address it within their patching cycles.
Vulnerability Details
The vulnerability in MicroWord eScan Antivirus is identified as CVE-2025-1364. It was published on February 16, 2025, and has been classified as critical due to its possible exploitation via a stack-based buffer overflow. The specific function affected is passPrompt within the USB Protection Service component. The CVSS score of 4.8 indicates a medium severity, allowing for local exploitation with low complexity and low privileges required.
The vulnerability is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow).
Organizations should be aware of the affected product version, which is eScan Antivirus 7.0.32 on Linux. The publication date of the vulnerability is critical for understanding its impact timeline.
Technical Analysis
The root cause of this vulnerability stems from inadequate input validation in the passPrompt function, leading to potential stack-based buffer overflow when processing USB device inputs.
The attack vector is local, with low complexity required for exploitation. Attackers require low privileges and no user interaction is necessary, making it easier for an attacker who has local access to exploit this vulnerability.
The impact on confidentiality, integrity, and availability is classified as low. However, due to the nature of a buffer overflow, it poses a significant risk for unauthorized code execution, which could lead to further exploitation.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-1364 is considerable, especially for organizations utilizing the MicroWord eScan Antivirus software. The potential for local exploitation increases the blast radius, as any user with access to the system could attempt to leverage this vulnerability.
Organizations need to consider the implications of a successful exploit, which could lead to unauthorized access to sensitive data or system control. In light of the medium CVSS score and the absence of a vendor response to the disclosure, organizations should address this vulnerability in their immediate patching cycle.
The urgency for remediation is heightened by the potential for public exploit usage. Organizations should implement patches as soon as they are available to mitigate the risks posed by this vulnerability.
