Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4512578.
It is, therefore, affected by multiple vulnerabilities :

- An elevation of privilege vulnerability exists in Windows Text Service Framework (TSF) when the TSF server process does not validate the source of input or commands it receives. An attacker who successfully exploited this vulnerability could inject commands or read input sent through a malicious Input Method Editor (IME). This only affects systems that have installed an IME. (CVE-2019-1235)

- An information disclosure exists in the Windows Common Log File System (CLFS) driver when it fails to properly handle sandbox checks. An attacker who successfully exploited this vulnerability could potentially read data outside their expected limits. (CVE-2019-1282)

- An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2019-1274)

- An information disclosure vulnerability exists when Windows Hyper-V writes uninitialized memory to disk. An attacker could exploit the vulnerability by reading a file to recover kernel memory. (CVE-2019-1254)

- An elevation of privilege vulnerability exists when the Windows Update Delivery Optimization does not properly enforce file share permissions. An attacker who successfully exploited the vulnerability could overwrite files that require higher privileges than what the attacker already has. (CVE-2019-1289)

- An elevation of privilege vulnerability exists when the .NET Framework common language runtime (CLR) allows file creation in arbitrary locations. An attacker who successfully exploited this vulnerability could write files to folders that require higher privileges than what the attacker already has. (CVE-2019-1142)

- A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2019-1240, CVE-2019-1241, CVE-2019-1242, CVE-2019-1243, CVE-2019-1246, CVE-2019-1247, CVE-2019-1248, CVE-2019-1249, CVE-2019-1250)

- An elevation of privilege vulnerability exists in Windows store installer where WindowsApps directory is vulnerable to symbolic link attack. An attacker who successfully exploited this vulnerability could bypass access restrictions to add or remove files.
(CVE-2019-1270)

- An elevation of privilege vulnerability exists in Microsoft Compatibility Appraiser where a configuration file, with local privileges, is vulnerable to symbolic link and hard link attacks. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. (CVE-2019-1267)

- An elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC). An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2019-1269, CVE-2019-1272)

- A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2019-1280)

- An information disclosure vulnerability exists in Windows when the Windows SMB Client kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could potentially disclose contents of System memory.
(CVE-2019-1293)

- A cross-site-scripting (XSS) vulnerability exists when Active Directory Federation Services (ADFS) does not properly sanitize certain error messages. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected ADFS server. The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run scripts in the security context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim's identity to take actions on the ADFS site on behalf of the user, such as change permissions and delete content, and inject malicious content in the browser of the user. The security update addresses the vulnerability by helping to ensure that ADFS error handling properly sanitizes error messages. (CVE-2019-1273)

- An elevation of privilege vulnerability exists in Windows Audio Service when a malformed parameter is processed. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges when used in conjunction with another vulnerability. (CVE-2019-1277)

- An elevation of privilege vulnerability exists when the Diagnostics Hub Standard Collector Service improperly impersonates certain file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges. An attacker with unprivileged access to a vulnerable system could exploit this vulnerability. The security update addresses the vulnerability by ensuring the Diagnostics Hub Standard Collector Service properly impersonates file operations.
(CVE-2019-1232)

- An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs;
view, change, or delete data; or create new accounts with full user rights. (CVE-2019-1256, CVE-2019-1285)

- An elevation of privilege vulnerability exists when the Windows AppX Deployment Server improperly handles junctions. (CVE-2019-1253, CVE-2019-1303)

- A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-1208, CVE-2019-1236)

- An elevation of privilege vulnerability exists in the way that the Windows Network Connectivity Assistant handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2019-1287)

- A remote code execution vulnerability exists in the Windows Remote Desktop Client when a user connects to a malicious server. An attacker who successfully exploited this vulnerability could execute arbitrary code on the computer of the connecting client. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2019-1290, CVE-2019-1291)

- A security feature bypass vulnerability exists when Microsoft Browsers fail to validate the correct Security Zone of requests for specific URLs. This could allow an attacker to cause a user to access a URL in a less restricted Internet Security Zone than intended.
(CVE-2019-1220)
