CVE-2024-32631Network attack vector

Incorrect computations via ciCCIOTOPT out-of-bounds read

Published Apr 16, 2024 · Updated Aug 2, 2024

Out-of-bounds read in ASR Falcon/Crane firmware before CP01.057.067 allows remote authenticated users to cause incorrect computations. The ciCCIOTOPT routine reads beyond a buffer boundary during telephony processing, but ASR has not disclosed the specific unchecked field or boundary calculation. Exploitation requires high privileges and high-complexity network conditions; ASR reports incorrect computations but does not identify a specific crash or exposed data.
