A vulnerability in the management interface of MiVoice Business through 9.3 PR1 and MiVoice Business Express through 8.0 SP3 PR3 could allow an unauthenticated attacker (that has network access to the management interface) to conduct a buffer overflow attack due to insufficient validation of URL parameters. A successful exploit could allow arbitrary code execution.
