CVE-2022-31784
https://notcve.org/view.php?id=CVE-2022-31784
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. Una vulnerabilidad en la interfaz de administración de MiVoice Business versiones hasta 9.3 PR1 y MiVoice Business Express versiones hasta 8.0 SP3 PR3 podría permitir a un atacante no autenticado (que tenga acceso a la red de la interfaz de administración) conducir un ataque de desbordamiento del búfer debido a una comprobación insuficiente de los parámetros de la URL. Una explotación con éxito podría permitir la ejecución de código arbitrario • https://www.mitel.com/support/security-advisories https://www.mitel.com/support/security-advisories/mitel-product-security-advisory-22-0005 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2022-26143 – MiCollab, MiVoice Business Express Access Control Vulnerability
https://notcve.org/view.php?id=CVE-2022-26143
The TP-240 (aka tp240dvr) component in Mitel MiCollab before 9.4 SP1 FP1 and MiVoice Business Express through 8.1 allows remote attackers to obtain sensitive information and cause a denial of service (performance degradation and excessive outbound traffic). This was exploited in the wild in February and March 2022 for the TP240PhoneHome DDoS attack. El componente TP-240 (también conocido como tp240dvr) en Mitel MiCollab versiones anteriores a 9.4 SP1 FP1 y MiVoice Business Express versiones hasta 8.1, permite a atacantes remotos obtener información confidencial y causar una denegación de servicio (degradación del rendimiento y tráfico saliente excesivo). Esto fue explotado "in the wild" en febrero y marzo de 2022 para el ataque DDoS TP240PhoneHome A vulnerability has been identified in MiCollab and MiVoice Business Express that may allow a malicious actor to gain unauthorized access to sensitive information and services, cause performance degradations or a denial of service condition on the affected system. • https://arstechnica.com/information-technology/2022/03/ddosers-use-new-method-capable-of-amplifying-traffic-by-a-factor-of-4-billion https://blog.cloudflare.com/cve-2022-26143 https://news.ycombinator.com/item?id=30614073 https://team-cymru.com/blog/2022/03/08/record-breaking-ddos-potential-discovered-cve-2022-26143 https://www.akamai.com/blog/security/phone-home-ddos-attack-vector https://www.mitel.com/en-ca/support/security-advisories/mitel-product-security-advisory-22-0001 https://www.sha • CWE-306: Missing Authentication for Critical Function •
CVE-2018-18819
https://notcve.org/view.php?id=CVE-2018-18819
A vulnerability in the web conference chat component of MiCollab, versions 7.3 PR6 (7.3.0.601) and earlier, and 8.0 (8.0.0.40) through 8.0 SP2 FP2 (8.0.2.202), and MiVoice Business Express versions 7.3 PR3 (7.3.1.302) and earlier, and 8.0 (8.0.0.40) through 8.0 SP2 FP1 (8.0.2.202), could allow creation of unauthorized chat sessions, due to insufficient access controls. A successful exploit could allow execution of arbitrary commands. Una vulnerabilidad en el componente de chat de conferencia web de MiCollab, versiones 7.3 PR6 (7.3.0.601) y anteriores, y versiones 8.0 (8.0.0.40) hasta 8.0 SP2 FP2 (8.0.2.202), y MiVoice Business Express versiones 7.3 PR3 (7.3.1.302 ) y anteriores, y versiones 8.0 (8.0.0.40) hasta 8.0 SP2 FP1 (8.0.2.202), podrían permitir la creación de sesiones de chat no autorizadas, debido a controles de acceso insuficientes.

CVE-2018-3639 – AMD / ARM / Intel - Speculative Execution Variant 4 Speculative Store Bypass
https://notcve.org/view.php?id=CVE-2018-3639
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. Los sistemas con microprocesadores que emplean la ejecución especulativa y que realizan la ejecución especulativa de lecturas de memoria antes de que se conozcan las direcciones de todas las anteriores escrituras de memoria podrían permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un análisis de canal lateral. Esto también se conoce como Speculative Store Bypass (SSB), Variant 4. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://www.exploit-db.com/exploits/44695 https://github.com/mmxsrup/CVE-2018-3639 https://github.com/Shuiliusheng/CVE-2018-3639-specter-v4- https://github.com/malindarathnayake/Intel-CVE-2018-3639-Mitigation_RegistryUpdate http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00007.html http://support.lenovo.com/us/en/solutions/LEN-2213 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
