Title: State-sponsored groups exploit bug in Microsoft Exchange servers

Description: The U.S. Department of Defense warned that multiple state-sponsored actors are exploiting a vulnerability in Microsoft Exchange servers. The bug was disclosed and patched in February, but many users out there have not updated their software. Attackers can send malicious, specially crafted requests to the Exchange control panel. The vulnerability allows adversaries to change serialized data to be unserialized, which allows them to run malicious code on the server's backend at the system level.

ID: CVE-2020-0688

Title: Microsoft Windows Installer Elevation of Privilege Vulnerability

Vendor: Microsoft

Description: An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links. An attacker who successfully exploited this vulnerability could bypass access restrictions to add or remove files.

CVSS v3 Base Score: 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

ID: CVE-2020-8597

Title: pppd EAP Processing Buffer Overflow Vulnerability ("Ghostcat")

Vendor: Multi-Vendor

Description: pppd (Point to Point Protocol Daemon) is vulnerable to buffer overflow due to a flaw in Extensible Authentication Protocol (EAP) packet processing in eap_request and eap_response subroutines. The vulnerability is in the logic of the eap parsing code. By sending an unsolicited EAP packet to a vulnerable ppp client or server, an unauthenticated remote attacker could cause memory corruption in the pppd process, which may allow for arbitrary code execution.
