TeleMessage TM SGNL vulnerability
TeleMessage TM SGNL exposes a heap dump endpoint via insecurely configured Spring Boot Actuator, allowing unauthenticated access to sensitive memory contents.
Verdict
Today item — known-exploited.
An exposed /heapdump endpoint permits attackers to extract heap memory dumps containing credentials, session tokens, and application secrets without authentication, enabling lateral movement and privilege escalation.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
7 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-07-01).
Probability (EPSS)
EPSS 0.07857 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: TeleMessage, TM SGNL. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-1188 Insecure Default Initialization — weakness family: Authorization / access control.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I discover the exposed /heapdump endpoint is accessible without credentials.
Business
Attackers gain direct access to application memory containing sensitive data.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I download the heap dump and extract plaintext credentials and API tokens from memory.
Business
Compromised credentials enable unauthorized access to user accounts and backend systems.
3
Lateral reach — past segmentation narrative 3
Attacker
I use extracted tokens to impersonate legitimate users and access protected resources.
Business
User data confidentiality is breached; attackers gain persistent access to the platform.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
