CVE-2003-5003Public exploitNetwork attack vector

Browser script execution via undisclosed handler input

Published Mar 28, 2022 · Updated Aug 8, 2024

Cross-site scripting in the Update Handler of ISS BlackICE PC Protection allows remote attackers to inject script via unspecified input. IBM's CVE record identifies neither the input field nor the handler operation that fails to neutralize it, so the implementation mechanism remains undisclosed. Successful exploitation requires user interaction and permits limited reading or alteration of data and a limited service interruption.
