Arbitrary code execution via improperly processed updates
Published May 25, 2020 · Updated Aug 4, 2024
Improper data processing in Cybozu Desktop 2 for Windows 2.0.23 through 2.2.40 allows remote attackers to execute arbitrary code. The software-update path applies update data without adequate validation; the vendor withholds the detailed operation and reproduction steps. Exploitation requires user interaction and a man-in-the-middle position or controlled update subdomain, and code runs in the client context.
