Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

A vulnerability in the conferencing component of Mitel MiVoice Connect, versions R1707-PREM SP1 (21.84.5535.0) and earlier, and Mitel ST 14.2, versions GA27 (19.49.5200.0) and earlier, could allow an unauthenticated attacker to conduct an SQL injection attack due to insufficient input validation for the signin interface. A successful exploit could allow an attacker to extract sensitive information from the database.

A vulnerability in the conferencing component of Mitel MiVoice Connect, versions R1707-PREM SP1 (21.84.5535.0) and earlier, and Mitel ST 14.2, versions GA27 (19.49.5200.0) and earlier, could allow an unauthenticated attacker to conduct a reflected cross-site scripting (XSS) attack due to insufficient validation for the launch_presenter.php page. A successful exploit could allow an attacker to execute arbitrary scripts.
