CVE-2025-48026Network attack vector

Unauthenticated file disclosure via unsanitized path input

Published Jun 23, 2025 · Updated Jun 24, 2025

Path traversal in the WebApl component of Mitel OpenScape Xpressions V7R1 FR5 HF43 P913 and earlier allows remote attackers to read OS files. WebApl insufficiently sanitizes attacker-controlled path input before using it to select a local file, allowing traversal outside the intended directory. No authentication or user interaction is required; exposed files can include voicemail, faxes, names, and email addresses.
