CVE-2023-3261Network attack vector

Service interruption via librta.so buffer overflow

Published Aug 14, 2023 · Updated Oct 9, 2024

Buffer overflow in librta.so.0.0.0 in Dataprobe iBoot PDU 1.43.03312023 and earlier allows remote attackers to interrupt service. The public record names the shared library but does not disclose the input path, function, or unchecked memory operation that overruns the buffer. Unauthenticated network access is sufficient; exploitation can disrupt every interaction that depends on the binary, including web login.
