Sensitive information disclosure via out-of-bounds read
Published Apr 20, 2023 · Updated Feb 5, 2025
Out-of-bounds read in the msprox endpoint of Sonos One 70.3-35220 allows network-adjacent attackers to disclose sensitive information. The endpoint does not validate user-supplied data before a buffer read, causing the read to continue beyond the allocated boundary. No authentication is required; the direct effect is disclosure, which can support a separate vulnerability chain that executes code as root.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
