CVE-2025-48928 is a medium-severity vulnerability associated with the Smarsh TeleMessage service. This vulnerability allows the exposure of sensitive information, specifically passwords, due to the mishandling of heap content in a JSP application. The issue arises from the application's core dump feature, which can inadvertently include previously transmitted passwords over HTTP. This vulnerability was actively exploited in the wild in May 2025, highlighting the urgency for organizations to address it.
With a CVSS score of 4.0, this vulnerability is classified as medium severity. The exploitability of this vulnerability is rated as critical, emphasizing the need for immediate attention from security teams. Organizations using this service are at risk of unauthorized access to sensitive data, which could lead to significant breaches and compliance issues. Therefore, organizations should prioritize patching immediately.
The vulnerability was published on May 28, 2025, and has been included in the Known Exploited Vulnerabilities (KEV) catalog. Organizations should take this warning seriously and implement the necessary mitigations to safeguard their data.
To ensure the security of their systems and data, organizations are advised to follow the vendor's instructions for mitigations or discontinue the use of the product if such mitigations cannot be implemented.
Vulnerability Details
The vulnerability in the TeleMessage service is classified as CWE-528 and CWE-552. The heap content exposure can lead to the inclusion of sensitive information in core dumps, putting user data at risk. The vulnerability affects the TeleMessage application in all versions prior to the vendor's patch released after May 5, 2025.
Technical Analysis
The root cause of CVE-2025-48928 lies in the handling of heap memory within the JSP application. The application allows for the exposure of sensitive data due to improper management of core dump files. The attack vector is local, which means that an attacker must have local access to exploit this vulnerability. The attack complexity is low, and no user interaction is required, making it a significant risk for organizations.
The impact on confidentiality is low, as it primarily involves the exposure of passwords, while integrity and availability are not directly affected. Organizations must consider this vulnerability's implications, especially in environments where sensitive data handling is critical.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to sensitive data. Given the nature of the vulnerability, it could lead to significant data breaches, damaging reputations and leading to legal ramifications. The blast radius can include all users of the TeleMessage service who have transmitted passwords over HTTP. Organizations should assess their exposure and prioritize remediation based on this vulnerability's critical exploitability and KEV status.
An urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. Implementing mitigations is essential to prevent exploitation.
