CVE-2003-5002Network attack vector

Update data disclosure via cleartext transmission

Published Mar 28, 2022 · Updated Aug 8, 2024

Cleartext transmission in the Update Handler of Internet Security Systems BlackICE PC Protection allows man-in-the-middle attackers to read update data. The handler sends data over an unencrypted update channel, but the published record does not identify the data, endpoint, protocol, or triggering request. Network-path access during an update is required, and the record reports confidentiality exposure only for an unsupported product.
