CVE-2025-3355Network attack vector

Unauthenticated file read via dot-dot traversal

Published Oct 30, 2025 · Updated Oct 30, 2025

Path traversal in IBM Tivoli Monitoring 6.3.0.7 through 6.3.0.7 Service Pack 21 allows remote attackers to read arbitrary files. The KT1 component accepts crafted URL paths containing dot-dot sequences and resolves them outside the intended directory for local-file reads. Unauthenticated network access to a non-TLS Agent API is required; TLS-only Agent communication prevents exposure, and no file modification is attributed to this CVE.
