What the vulnerability is
CVE-2025-48927 is a vulnerability in TeleMessage TM SGNL categorized as the initialization of a resource with an insecure default (CWE-1188). The flaw stems from the configuration of the Spring Boot Actuator, which leaves a heap dump endpoint exposed at the /heapdump URI.
Exposure and applicability
This vulnerability affects deployments of TeleMessage TM SGNL where the Spring Boot Actuator is configured with the default exposure of the heap dump endpoint. Organizations utilizing this product should identify whether their instances are accessible via the affected URI to determine their level of exposure.
Remediation priorities
Based on our analysis, defenders should prioritize actions based on the availability of vendor-supplied fixes:
- Vendor Mitigation Application: The primary priority is to apply mitigations according to official vendor instructions.
- Cloud Service Alignment: For cloud-based deployments, organizations should align their remediation efforts with BOD 22-01 guidance.
- Product Decommissioning: In scenarios where vendor mitigations are unavailable or cannot be located, the recommended course of action is to discontinue use of the product to eliminate the exposure path.
How to validate remediation
Verification must move beyond simple version checks. To confirm that the vulnerability has been mitigated, defenders should verify that the /heapdump URI is no longer accessible or does not return a heap dump file.
It is important to distinguish between the deployment of a patch and the verification of the result; a successful mitigation is confirmed only when the specific endpoint is proven unreachable or disabled.
Limits and open questions
There are several unknowns regarding this vulnerability. It is currently unknown if this flaw has been utilized in known ransomware campaigns. Additionally, the source does not provide specific patch versions, leaving it to the user to verify current availability through vendor channels. Residual risk remains if compensating controls are used instead of a direct configuration fix, as other Actuator endpoints may remain exposed depending on the broader Spring Boot configuration.
