The TeleMessage service through 2025-05-05 configures Spring Boot Actuator with an exposed heap dump endpoint at a /heapdump URI, as exploited in the wild in May 2025. This vulnerability allows unauthorized access to sensitive application data and poses a risk to confidentiality. With a CVSS score of 5.3, this vulnerability is classified as medium severity, indicating a notable but manageable risk for organizations.
Risk to organizations includes potential data exposure and unauthorized access to application internals. Attackers may leverage this vulnerability to gain insights into application operations, which may lead to further attacks or data breaches. Urgency for defenders is high, and organizations should address this vulnerability in their priority patch cycle.
As of the last update, there is no public exploit confirmed for this vulnerability. However, given its classification, organizations should remain vigilant and monitor for any updates from the vendor regarding potential exploits. Organizations should prioritize patching immediately.
Monitoring and remediation strategies should be implemented to safeguard systems. Organizations are encouraged to follow the vendor’s guidance for mitigation, as well as relevant recommendations from cybersecurity frameworks.
Vulnerability Details
The vulnerability is detailed as follows: it affects the TeleMessage service due to improper configuration of Spring Boot Actuator, exposing a heap dump endpoint that could be accessed without authentication. The CVSS score is 5.3, indicating medium severity, which highlights the need for immediate attention.
The vulnerability was published on May 28, 2025, and is classified under CWE-1188. This classification signifies that the vulnerability is related to the configuration of sensitive application features that should not be exposed.
Technical Analysis
The root cause of this vulnerability lies in the configuration settings of the Spring Boot Actuator within the TeleMessage application. By exposing the heap dump endpoint, sensitive information is made available to unauthorized users. The attack vector is network-based, with low complexity, requiring no privileges or user interaction to exploit.
The vulnerability affects confidentiality, as it allows potential access to sensitive data contained in the heap dump. However, there is no impact on integrity or availability, as the exploitation focuses solely on data exposure without affecting the application's operational capacity.
Risk & Impact Analysis
Real-world deployment risk is significant due to the potential exposure of sensitive data. Organizations utilizing the TeleMessage service should be aware of the risks associated with unauthorized access to application data. The blast radius could be extensive, affecting not only the application but also any sensitive data processed through it.
Given the CVSS score, the urgency for remediation is high, especially for those within the KEV catalog. Organizations should prioritize addressing this vulnerability to mitigate potential impacts on their operational integrity and data confidentiality.
